Mr.
Chairman and Members of the Committee:
I
am pleased to be here today to discuss our analysis of the information security
controls over unclassified systems of the Department of Commerce (Commerce).
Dramatic increases in computer interconnectivity, especially in the use of the
Internet, are revolutionizing the way our government, our nation, and much of
the world communicate and conduct business, bringing vast amounts of information
and myriad resources and activities literally at our fingertips. However, along
with the enormous benefits it brings, this widespread interconnectivity poses
significant risks to our computer systems, and more important, to the critical
operations and infrastructures they support.
As
with other organizations, Commerce relies extensively on computerized systems
and electronic data to support its mission. Moreover, Commerce generates and
disseminates some of the nation's most important economic information that is of
paramount interest to U.S. businesses, policymakers, and researchers.
Accordingly, the security of its systems and data is essential to avoiding
disruption in critical operations, data tampering, fraud, and inappropriate
disclosure of sensitive information. Further, there has be a dramatic rise in
the number and sophistication of cyberattacks on federal information systems. My
testimony today specifically focuses on the effectiveness of Commerce’s (1)
logical access controls and other information system controls over its
computerized data,
(2) incident detection and response capabilities,and (3) information security management program and
related procedures. We
reviewed Commerce’s information security controls and currently have a draft
report at Commerce for comment.
At
the seven Commerce organizations we reviewed,
significant and pervasive computer security weaknesses exist that place
sensitive Commerce systems
at serious risk. Using readily available software and common techniques, we
demonstrated the ability to penetrate sensitive Commerce systems from both
inside Commerce and remotely, such as through the Internet. Individuals, both
within and outside Commerce, could gain unauthorized access to these systems and
read, copy, modify, and delete sensitive economic, financial, personnel, and
confidential business data. Moreover, intruders could disrupt the operations of
systems that are critical to the mission of the department. Additionally,
unauthorized access to sensitive systems may not be detected in time to prevent
or minimize damage. The underlying cause for the numerous weaknesses we
identified was the lack of an effective program to manage information security.
We
identified vulnerabilities in four key areas in the bureaus we reviewed:
·
First, controls intended to protect information
systems and critical data from unauthorized access are ineffectively
implemented, leaving sensitive systems highly susceptible to intrusions or
disruptions. Specifically,
-
Systems were either not configured to require
passwords—including powerful systems administrator accounts—or, if passwords
were required, they were relatively easy to guess, such as the word
“password” or commonly known default passwords supplied by vendors. Further,
(1) a significant number of passwords never expired, (2) individuals had
unlimited attempts to guess passwords, and (3) unencrypted passwords, including
those having powerful system administrator functions, could be widely viewed.
Commerce bureaus also granted excessive system administration privileges to
employees who did not require them, including 20 individuals who had powerful
system privileges that should be used only in exceptional circumstances, such as
recovery from a power failure.
-
The configuration of Commerce operating systems
exposed excessive amounts of system information to anyone, without the need for
authentication, allowing potential attackers to collect systems information that
could be used to circumvent security controls and gain unauthorized access. In
addition, Commerce did not properly configure operating systems to ensure that
they would be available to support bureau missions or prevent the corruption of
important data. For example, in a large computer system affecting several
bureaus, thousands of important programs had not been assigned unique names,
which could result in unintended programs being inadvertently run, potentially
corrupting data or disrupting system operations. In this same system, because
critical parts of the operating system were shared by the test and production
systems, changes in either system could corrupt or shut down the other system.
Additionally, unnecessary and poorly configured system functions existed on
important computer systems in all bureaus we reviewed, allowing us to gain
access from the Internet.
-
None of the Commerce bureaus reviewed had effective
external and internal network security controls. Our testing demonstrated that
individuals, both within and outside Commerce, could compromise external and
internal security controls to gain extensive unauthorized access to the
department’s networks and systems. We obtained such access as a result of
weakly configured external control devices, poorly controlled dial-up modems,
and ineffective internal network controls.
·
Second, we found other control weaknesses, including
inadequate
(1) segregation of computer duties of the staff to mitigate the risk of errors
or fraud, (2) control of software changes to ensure that only authorized and fully tested software is placed in operation,
and
(3) development of comprehensive and completed recovery plans to ensure the
continuity of service in the event of a service disruption.
·
Third, Commerce is not adequately (1) preventing
intrusions before they occur, (2) detecting intrusions as they occur, (3)
responding to successful intrusions, or (4) reporting intrusions to staff and
management. Thus, there is little assurance that unauthorized attempts to access
sensitive information will be identified and appropriate actions taken in time
to prevent or minimize damage. For example, Commerce has not instituted key
measures to prevent incidents, such as acquiring software updates to correct
known vulnerabilities. During our testing we discovered 20 systems with known
vulnerabilities for which patches were available but not installed. As a result
of ineffective detection capabilities, the tested bureaus were generally unable
to detect our extensive intrusion activities (only two of the bureaus had
installed intrusion detection systems). Also, only one of the bureaus has
established incident response procedures; in two instances when our activity was
detected, Commerce employees who detected our testing inappropriately responded
by launching attacks against our systems. Moreover, these two incidents were
never reported to the bureaus’ security officer.
·
Fourth, and most important, Commerce does not have
an effective departmentwide information security management program to ensure
that sensitive data and critical operations are adequately addressed and that
appropriate security controls are in place to protect them. Key issues include
-
Lack
of a strong centralized management function to oversee and coordinate
departmentwide security-related activities. At the time of our
review, Commerce's CIO, who had broad responsibility for information security
throughout the department, said that he believed that he did not have sufficient
resources or the authority to implement this program. This lack of a centralized
approach to managing security is particularly risky considering the widespread
interconnectivity of Commerce's systems.
-
Widespread
lack of risk assessment. Commerce is doing little to understand and
manage risks to its systems. For example, as of March 2001, of the bureaus' 94
sensitive systems we reviewed, 91 did not have documented risk assessments, 87
had no security plans, and none were authorized[6]
for processing by Commerce management. Consequently, most of
the bureaus' systems are being operated without considering the risks associated
with their immediate environment. Moreover, several bureau officials
acknowledged that they had not considered how vulnerabilities in systems that
interconnected with theirs could undermine the security of their own systems.
-
Significantly
outdated and incomplete information security policies. Commerce's
information security policy, developed in 1993 and partially revised in 1995,
does not reflect current federal requirements for managing computer security on
a continuing basis, developing security plans, authorizing processing, providing
security awareness training, or performing system reviews. Moreover, Commerce
has not updated its policy to reflect the risks of Internet use and has no
policies establishing baseline security requirements for all systems. For
example, there is no policy specifying required attributes for passwords, such
as minimum length and the inclusion of special characters.
-
Inadequately
promoted security awareness and training. Although each of the seven
bureaus reviewed have informal programs in place, none have documented computer
security training procedures that meet federal requirements for ensuring that
security risks and responsibilities are understood by all managers, users, and
system administrators.
-
Lack
of an ongoing program to test and evaluate security controls. No
oversight reviews of the Commerce bureaus’ systems have been performed by the
staff of Commerce’s information security program. Furthermore, the bureaus we
reviewed do not monitor the effectiveness of their information security. Only
one of the bureaus has performed isolated tests of its systems.
The
lack of an effective information security program is exacerbated by Commerce's
highly interconnected computing environment in which the vulnerabilities of
individual systems affect the security of systems in the entire department. A
compromise in a single poorly secured system can undermine the security of the
multiple systems that connect to it.
In
the last 2 years, the Commerce CIO introduced several initiatives to improve the
security posture of the department, including a summary evaluation of
information security based on bureau self-assessments and related follow-up.
Also, in June 2001, after our fieldwork was completed, the Secretary of Commerce
approved a high-level Commerce information technology (IT) restructuring plan.
The acting CIO stated that Commerce is developing a more detailedrestructuring
implementationplan plan. Regardless of its particular approach, we have made
recommendations that Commerce needs to implement in order to address the
weaknesses in its information security controls.
In
the rest of my statement today, I will discuss in more detail the results of our
review of Commerce’s information security controls; these results are included
in our draft report, which also contains more detailed recommendations.
Information
security is an important consideration for any organization that depends on
information systems to carry out its mission. The dramatic expansion in computer
interconnectivity and the exponential increase in the use of the Internet are
changing the way our government, the nation, and much of the world communicate
and conduct business. However, risks are significant, and they are growing. The
number of computer security incidents reported to the CERT Coordination Centerâ
(CERT/CC)
rose from 9,859 in 1999 to 21,756 in 2000. For the first 6 months of 2001, the
number reported was 15,476.
As
the number of individuals with computer skills has increased, more intrusion or
“hacking” tools have become readily available and relatively easy to use. A
potential hacker can literally download tools from the Internet and "point
and click" to start a hack. According to a recent National Institute of Standards and Technology (NIST) publication,
hackers post 30 to 40 new tools to hacking sites on the Internet every month.
The successful cyber attacks against such well-known U.S. e-commerce Internet
sites as eBay, Amazon.com, and CNN.com by a 15-year old "script kiddie"
in February 2000 illustrate the risks. Without proper safeguards, these
developments make it easier for individuals and groups with malicious intentions
to gain unauthorized access to systems and use their access to obtain sensitive
information, commit fraud, disrupt operations, or launch attacks against other
organizations’ sites.
|
Federal
Systems Are At Risk
|
Government
officials are increasingly concerned about federal computer systems, which
process, store, and transmit enormous amounts of sensitive data and are
indispensable to many federal operations. The federal government’s systems are
riddled with weaknesses that continue to put critical operations at risk. Since
October 1998, the Federal Computer Incident Response Center's (FedCIRC)
records have shown an increasing trend in the number of attacks targeting
government systems. In 1998 FedCIRC documented 376 incidents affecting 2,732 federal civilian systems and 86 military
systems. In
2000, the number of attacks rose to 586 incidents affecting 575,568 federal
systems and 148 of their military counterparts. Moreover, according to FedCIRC,
these numbers reflect only reported incidents, which it estimates do not include
as many as 80 percent of actual security incidents. According to FedCIRC, 155 of
the incidents reported in 2000, which occurred at 32 agencies, resulted in what
is known as a “root compromise.”
For at least five of the root compromises, government officials were able to
verify that access to sensitive information had been obtained.
How
well federal agencies are addressing these risks is a topic of increasing
interest in the executive and legislative branches. In January 2000, President
Clinton issued a National
Plan for Information Systems Protection
and designated computer security and critical infrastructure protection a
priority management objective in his fiscal year 2001 budget. The new
administration, federal agencies, and private industry have collaboratively
begun to prepare a new version of the national plan that will outline an
integrated approach to computer security and critical infrastructure protection.
The
Congress, too, is increasingly interested in computer security, as evidenced by
important hearings held during 1999, 2000, and 2001 on ways to strengthen
information security practices throughout the federal government and on progress
at specific agencies in addressing known vulnerabilities. Furthermore, in
October 2000, the Congress included government information security reform
provisions in the fiscal year 2001 National Defense Authorization Act. These
provisions seek to ensure proper management and security for federal information
systems by calling for agencies to adopt risk management practices that are
consistent with those summarized in our 1998 Executive
Guide.
The provisions also require annual agency program reviews and Inspector General
(IG) evaluations that must be reported to the Office of Management and Budget
(OMB) as part of the budget process.
The
federal CIO Council and others have also initiated several projects that are
intended to promote and support security improvements to federal information
systems. Over the past year, the CIO Council, working with NIST, OMB, and us,
developed the Federal Information Technology Security Assessment Framework.
The framework provides agencies with a self-assessment methodology to determine
the current status of their security programs and to establish targets for
improvement. OMB has instructed agencies to use the framework to fulfill their
annual assessment and reporting obligations.
Since
1996, our analyses of information security at major federal agencies have shown
that systems are not being adequately protected. Our previous reports, and those
of agency IGs, describe persistent computer security weaknesses that place a
variety of critical federal operations at risk of inappropriate disclosures,
fraud, and disruption.
This body of audit evidence has led us, since 1997, to designate computer
security as a governmentwide high-risk area.
Our
most recent summary analysis of federal information systems found that
significant computer security weaknesses had been identified in 24 of the
largest federal agencies, including Commerce.
During December 2000 and January 2001, Commerce's IG also reported significant
computer security weaknesses in several of the department's bureaus and, in
February 2001, reported information security as a material weakness affecting
the department's ability to produce accurate data for financial statements.
The report stated that there were weaknesses in several areas, including
entitywide security management, access controls, software change controls,
segregation of duties, and service continuity planning. Moreover, a recent IG
assessment of the department's information security program found fundamental
weaknesses in the areas of policy and oversight.
Also, the IG designated information security as one of the top ten management
challenges for the department.
Commerce's
missions are among the most diverse of the federal government's cabinet
departments, covering a wide range of responsibilities that include observing
and managing natural resources and the environment; promoting commerce, regional
development, and scientific research; and collecting, analyzing, and
disseminating statistical information. Commerce employs about 40,000 people in
fourteen operating bureaus with numerous offices in the U.S. and overseas, each
pursuing disparate programs and activities.
|
Commerce
Missions
Are Diverse
|
IT
is a critical tool for Commerce to support these missions. The department spends
significant resources—reportedly over $1.5 billion in fiscal year 2000—on IT
systems and services. As a percentage of total agency expenditures on IT,
Commerce ranks among the top agencies in the federal government, with 17 percent
of its $9-billion fiscal year 2000 budget reported as spent on IT.
A
primary mission of Commerce is to promote job creation and improved living
standards for all Americans by furthering U.S. economic growth, and the seven
bureaus we reviewed support this mission through a wide array of programs and
services. Commerce uses IT to generate and disseminate some of the nation’s
most important economic information. The International Trade Administration (ITA)
promotes the export of U.S. goods and services—which amounted to approximately
$1.1 trillion in fiscal year 2000. Millions of American jobs depend on exports,
and with 96 percent of the world's consumers living outside U.S. borders,
international trade is increasingly important to supporting this mission. The
Economics and Statistics Administration (ESA) develops, prepares, analyzes, and
disseminates important indicators of the U.S. that present basic information on
such key issues as economic growth, regional development, and the U.S. role in
the world economy. This information is of paramount interest to researchers,
business, and policymakers.
The
Bureau of Export Administration (BXA), whose efforts supported sales of
approximately $4.2 billion in fiscal year 1999, assists in stimulating the
growth of U.S. exports while protecting national security interests by helping
to stop the proliferation of weapons of mass destruction. Sensitive data such as
that relating to national security, nuclear proliferation, missile technology,
and chemical and biological warfare reside in this bureau's systems.
Commerce's
ability to fulfill its mission depends on the confidentiality, integrity, and
availability of this sensitive information. For example, export data residing in
the BXA systems reflect technologies that have both civil and military
applications; the misuse, modification, or deletion of these data could threaten
our national security or public safety and affect foreign policy. Much of these
data are also business proprietary. If it were compromised, the business could
not only lose its market share, but dangerous technologies might end up in the
hands of renegade nations who threaten our national security or that of other
nations.
|
Commerce’s
IT
Infrastructure Is
Decentralized
|
Commerce's
IT infrastructure is decentralized. Although the Commerce IT Review Board
approves major acquisitions, most bureaus have their own IT budgets and act
independently to acquire, develop, operate, and maintain their own
infrastructure. For example, Commerce has 14 different data centers, diverse
hardware platforms and software environments, and 20 independently managed
e-mail systems. The bureaus also develop and control their own individual
networks to serve their specific needs. These networks vary greatly in size and
complexity. For example, one bureau has as many as 155 local area networks and
3,000 users spread over 50 states and 80 countries. Some of these networks are
owned, operated, and managed by individual programs within the same bureau.
Because
Commerce does not have a single, departmentwide common network infrastructure to
facilitate data communications across the department, the bureaus have
established their own access paths to the Internet, which they rely on to
communicate with one another. In April 2001, the department awarded a contract
for a $4 million project to consolidate the individual bureaus' local area
networks within its headquarters building onto a common network infrastructure.
However, until this project is completed, each of the bureaus is expected to
continue to configure, operate, and maintain its own unique networks.

Improvements
to
Information Security
Have Been Initiated
|
Recognizing
the importance of its data and operations, in September 1993 Commerce
established departmentwide information security policies that defined and
assigned a full set of security responsibilities, ranging from the department
level down to individual system owners and users within the bureaus. Since 1998,
the Commerce CIO position has been responsible for developing and implementing
the department’s information security program. An information security
manager, under the direction of the CIO's Office of Information Policy,
Planning, and Review, is tasked with carrying out the responsibilities of the
program. The CIO's responsibilities for the security of classified systems has
been delegated to the Office of Security.
In
the last 2 years, the CIO introduced several initiatives that are essential to
improving the security posture of the department. After a 1999 contracted
evaluation of the bureaus' security plans determined that 43 percent of
Commerce's most critical assets did not have current information system security
plans, the CIO issued a memorandum calling for the bureaus to prepare security
plans that comply with federal regulations. Also, in May 2000, the Office of the
CIO performed a summary evaluation of the status of all the bureaus' information
security based on the bureaus' own self-assessments. The results determined that
overall information security program compliance was minimal, that no formal
information security awareness and training programs were provided by the
bureaus, and that incident response capabilities were either absent or informal.
The Commerce IG indicated that subsequent meetings between the Office of the CIO
and the bureaus led to improvements. The Office of the CIO plans to conduct
another evaluation this year and, based on a comparison with last year's
results, measure the bureaus’ success in strengthening their security
postures.
Finally,
for the past year, the CIO attempted to restructure the department's IT
management to increase his span of control over information security within the
bureaus by enforcing his oversight authority and involvement in budgeting for IT
resources. However, this initiative was not approved before the CIO’s
resignation in 2001. In June 2001, after our fieldwork was completed, the
Secretary of Commerce approved a high-level Commerce IT restructuring plan. The
acting CIO stated that a task force is developing a more detailed implementation
plan.
|
Logical
Access Controls Were Inadequate
|
A
basic
management objective for any organization is the protection of its
information systems and critical data from unauthorized access. Organizations
accomplish this objective by establishing controls that limit access to only
authorized users, effectively configuring their operating systems, and securely
implementing networks. However, our tests identified weaknesses in each of these
control areas in all of the Commerce bureaus we reviewed. We demonstrated that
individuals, both external and internal to Commerce, could compromise security
controls to gain extensive unauthorized access to Commerce networks and systems.
These weaknesses place the bureaus’ information systems at risk of
unauthorized access, which could lead to the improper
disclosure, modification, or deletion of sensitive information and
the disruption of critical operations. As previously noted, because
of the sensitivity of specific weaknesses, we plan to issue a report designated
for "Limited Official Use," which describes in more detail each of the
computer security weaknesses identified and offers specific recommendations for
correcting them.
|
System
Access
Controls Were Weak
|
Effective
system access controls provide mechanisms that require users to identify
themselves and authenticate
their identity, limit the use of system administrator capabilities to authorized
individuals, and protect sensitive system and data files. As with many
organizations, passwords are Commerce’s primary means of authenticating user
identity. Because system administrator capabilities provide the ability to read,
modify, or delete any data or files on the system and modify the operating
system to create access paths into the system, such capabilities should be
limited to the minimum access levels necessary for systems personnel to perform
their duties. Also, information can be protected by using controls that limit an
individual’s ability to read, modify, or delete information stored in
sensitive system files.
User
ID and Password Management
Controls Were Not Effective
One
of the primary methods to prevent unauthorized access to information system
resources is through effective management of user IDs and passwords. To
accomplish this objective, organizations should establish controls that include
requirements to ensure that well-chosen passwords are required for user
authentication, passwords are changed periodically, the number of invalid
password attempts is limited to preclude password guessing, and the
confidentiality of passwords is maintained and protected.
All
Commerce bureaus reviewed were not effectively managing user IDs and passwords
to sufficiently reduce the risk that intruders
could gain unauthorized access to its information systems to (1) change
system access and other rules, (2) potentially read,
modify, and delete or redirect network traffic, and (3) read, modify, and delete
sensitive information. Specifically, systems
were either not configured to require passwords or, if passwords were required,
they were relatively easy to guess. For example,
·
powerful system administrator accounts did not
require passwords, allowing anyone who could connect to certain systems through
the network to log on as a system administrator without having to use a
password,
·
systems allowed users to change their passwords to a
blank password, completely circumventing the password control function,
·
passwords were easily guessed words, such as
"password,"
·
passwords were the same as the user's ID, and
·
commonly known default passwords set by vendors when
systems were originally shipped had never been changed.
Although
frequent password changes reduce the risk of continued unauthorized use of a
compromised password, systems in four of the bureaus reviewed had a significant
number of passwords that never required changing or did not have to be changed
for 273 years. Also, systems in six of the seven bureaus did not limit the
number of times an individual could try to log on to a user ID. Unlimited
attempts allow intruders to keep trying passwords until a correct password is
discovered.
Further,
all Commerce bureaus reviewed did not adequately protect the passwords of their
system users through measures such as encryption, as illustrated by the
following examples:
·
User
passwords were stored in readable text files that could be viewed by all users
on one bureau’s systems.
·
Files that store user passwords were not protected
from being copied by intruders, who could then take the copied password files
and decrypt user passwords. The decrypted passwords could then be used to gain
unauthorized access to systems by intruders masquerading as legitimate users.
·
Over 150 users of one system could read the
unencrypted password of a powerful system administrator's account.
Control
of System Administration
Functions Was Not Adequate
System
administrators perform important functions in support of the operations of
computer systems. These functions include defining security controls, granting
users access privileges, changing operating system configurations, and
monitoring system activity. In order to perform these functions, system
administrators have powerful privileges that enable them to manipulate operating
system and security controls. Privileges to perform these system administration
functions should be granted only to employees who require such privileges to
perform their responsibilities and who are specifically trained to understand
and exercise those privileges. Moreover, the level of privilege granted to
employees should not exceed the level required for them to perform their
assigned duties. Finally, systems should provide accountability for the actions
of system administrators on the systems.
However,
Commerce bureaus granted the use of excessive system administration privileges
to employees who did not require such privileges
to perform their responsibilities and who were not trained to
exercise them. For example, a very powerful system administration privilege that
should be used only in exceptional circumstances, such as recovery from a power
failure, was granted to 20 individuals.
These 20 individuals had the ability to access all of the information stored on
the system, change important system configurations that could affect the
system’s reliability, and run any program on the computer. Further, Commerce
management also acknowledged that not all staff with access to this
administrative privilege had been adequately trained.
On
other important systems in all seven bureaus, system administrators were sharing
user IDs
and passwords so that systems could not provide an audit trail of access by
system administrators, thereby limiting accountability. By not effectively
controlling the number of staff who exercise system administrator privileges,
restricting the level of such privileges granted to those required to perform
assigned duties, or ensuring that only well-trained staff have these privileges,
Commerce is increasing the
risk that unauthorized activity could occur and the security of
sensitive information be compromised.
Access
to Critical Systems
and Sensitive Data Files
Was Not Adequately Restricted
Access
privileges to individual critical systems and sensitive data files should be
restricted to authorized users. Not only does this restriction protect files
that may contain sensitive information from unauthorized access, but it also
provides another layer of protection against intruders who may have successfully
penetrated one system from significantly extending their unauthorized access and
activities to other systems. Examples of access privileges
are the capabilities to read, modify,
or delete a file. Privileges can be granted to individual users, to groups of
users, or to everyone who accesses the system.
Six
of the seven bureaus' systems were not configured to appropriately
restrict access to sensitive system and/or data files. For example, critical
system files could be modified by all users to allow them to bypass security
controls. Also, excessive access privileges to sensitive data files such as
export license applications were granted. Systems configured with excessive
file access privileges are extremely vulnerable to compromise
because such configurations could enable an intruder to read, modify, or delete
sensitive system and data files, or to disrupt the availability and integrity of
the system.
|
Operating
Systems
Were Ineffectively
Secured
|
Operating
system controls are essential to ensure that the computer systems and security
controls function as intended. Operating systems are relied on by all the
software and hardware in a computer system. Additionally, all users depend on
the proper operation of the operating system to provide a consistent and
reliable processing environment, which is essential to the availability and
reliability of the information stored and processed by the system.
Operating
system controls should limit the extent of information that systems provide to
facilitate system interconnectivity. Operating systems should be configured to
help ensure that systems are available and that information stored and processed
is not corrupted. Controls should also limit the functions
of the computer system to prevent insecure system configurations or the
existence of functions not needed to support the operations of the system. If
functions are not properly controlled, they can be used by intruders to
circumvent security controls.
Excessive
System
Information Was Exposed
To
facilitate interconnectivity between computer systems, operating systems are
configured to provide descriptive and technical information, such as version
numbers and system names, to other computer systems and individuals when
connections are being established. At the same time, however, systems should be
configured to limit the amount of information that is made available to other
systems and unidentified individuals because this information can be misused by
potential intruders to learn the characteristics and vulnerabilities of that
system to assist in intrusions.
Systems
in all bureaus reviewed were not configured to control excessive system
information from exposure to potential attackers. The configuration of Commerce
systems provided excessive amounts of information to anyone, including external
users, without the need for authentication. Our testing demonstrated that
potential attackers could collect information about systems, such as computer
names, types of operating systems, functions, version numbers, user information,
and other information that could be useful to circumvent security controls and
gain unauthorized access.
Operating
Systems Were
Poorly Configured
The
proper configuration of operating systems is important to ensuring the reliable
operation of computers and the continuous availability and integrity
of critical
information. Operating systems should be configured so that the security
controls throughout the system function effectively and the system can be
depended on to support the organization’s mission.
Commerce
bureaus did not properly configure operating systems to ensure that systems
would be available to support bureau missions or prevent the corruption of the
information relied on by management and the public. For example, in a large
computer system affecting several bureaus, there were thousands of important
programs that had not been assigned unique names. In some instances, as many as
six different programs all shared the same name, many of which were different
versions of the same program. Although typically the complexity of such a system
may require the installation of some programs that are identically named and
authorized programs must be able to bypass security in order to operate, there
were an excessive number of such programs installed on this system, many of
which were capable of bypassing security controls.
Because these
different programs are identically named, unintended programs could be
inadvertently run, potentially resulting in the corruption of data or disruption
of system operations. Also, because these powerful programs are duplicated,
there is an increased likelihood that they could be misused to bypass security
controls.
In
this same system, critical parts of the operating system were shared by the test
and production systems used to process U.S. export information. Because critical
parts were shared, as changes are made in the test system, these changes could
also affect the production system. Consequently, changes could be made in the
test system that would cause the production system to stop operating normally
and shut down. Changes in the test system could also cause important Commerce
data in the production system to become corrupted. Commerce management
acknowledged that the isolation between these two systems needed to be
strengthened to mitigate these risks.
Systems
Had Unnecessary and
Poorly Configured Functions
Operating
system functions should be limited to support only the capabilities needed by
each specific computer system. Moreover, these functions should be appropriately
configured. Unnecessary operating system functions can be used to gain
unauthorized access to a system and target that system for a denial-of-service
attack.
Poorly configured operating system functions can allow individuals to bypass
security controls and access sensitive information without requiring proper
identification and authentication.
Unnecessary
and poorly configured system functions existed on important computer systems in
all the bureaus we reviewed.
For example, unnecessary functions allowed us to gain access to a system from
the Internet. Through such access and other identified weaknesses, we were able
to gain system
administration privileges on that system and subsequently gain access to other
systems within other Commerce bureaus.
Also, poorly configured functions would have allowed users to
bypass security controls and gain unrestricted access to all programs and data.
|
Network
Security
Was Ineffective
|
Networks
are a series of interconnected information technology devices and software that
allow groups of individuals to share data, printers, communications systems,
electronic mail, and other resources. They provide the entry point for access to
electronic information assets and provide users with access to the information
technologies they need to satisfy the organization’s mission. Controls should
restrict access to networks from sources external to the network. Controls
should also limit the use of systems from sources internal to the network to
authorized users for authorized purposes.
External
threats include individuals outside an organization attempting to gain
unauthorized access to an organization’s networks using the Internet, other
networks, or dial-up modems. Another form of external threat is flooding a
network with large volumes of access requests so that the network is unable to
respond to legitimate requests, one type of denial-of-service attack. External
threats can be countered by implementing security controls on the perimeters of
the network, such as firewalls,
that limit user access and data interchange between systems and users within the
organization’s network and systems and users outside the network, especially
on the Internet. An example of perimeter defenses is only allowing pre-approved
computer systems from outside the network to exchange certain types of data with
computer systems inside the network. External network controls should guard the
perimeter of the network from connections with other systems and access by
individuals who are not authorized to connect with and use the network.
Internal
threats come from sources that are within an organization’s networks, such as
a disgruntled employee with access privileges who attempts to perform
unauthorized activities. Also, an intruder who has successfully penetrated a
network’s perimeter defenses becomes an internal threat when the intruder
attempts to compromise other parts of an organization’s network security as a
result of gaining access to one system within the network. For example, at
Commerce, users of one bureau who have no business need to access export license
information on another bureau’s network should not have had network
connections to that system.
External
network security controls should prevent unauthorized access from outside
threats, but if those controls fail, internal network security controls should
also prevent the intruder from gaining unauthorized access to other computer
systems within the network.
None
of the Commerce bureaus reviewed had effective external and internal network
security controls. Individuals, both within and outside Commerce, could
compromise external and internal security controls to gain extensive
unauthorized access to Commerce networks and systems. Bureaus employed a series
of external control
devices, such as firewalls, in some, but not all, of the access paths to their
networks. However, these controls did not effectively prevent unauthorized
access to Commerce networks from the Internet or through poorly controlled
dial-up modems that bypass external controls. For example,
four bureaus
had not configured their firewalls to adequately protect their information
systems from intruders on the Internet. Also, six dial-up modems were installed
so that anyone could connect to their network without having to use a password,
thereby circumventing the security controls provided by existing firewalls.
Our
testing demonstrated that, once access was gained by an unauthorized user on the
Internet or through a dial-up modem to one bureau’s networks, that intruder
could circumvent ineffective internal network controls to gain unauthorized
access to other networks within Commerce. Such weak internal network controls
could allow an unauthorized intruder or authorized user on one bureau’s
network to change the configuration of other bureaus’ network controls so that
the user could observe network traffic, including passwords and sensitive
information that Commerce transmits in readable clear text, and disrupt network
operations.
The
external and internal security controls of the different
Commerce
bureau networks
did not provide a consistent level of security in part because bureaus
independently configured and operated their networks as their own individual
networks. For example, four of the bureaus we reviewed had their own
independently controlled access points to the Internet.
Because
the different bureaus' networks
are actually logically interconnected and perform as one large interconnected
network, the ineffective network security
controls of one
bureau jeopardize the security of other bureaus’ networks. Weaknesses in the
external and internal network controls of the individual bureaus heighten the
risk that outside intruders with no prior knowledge of bureau user IDs or
passwords, as well as Commerce employees with malicious intent, could exploit
the other security weaknesses in access and operating system controls discussed
above to misuse, improperly disclose, or destroy sensitive information.
|
Other
Information
System Controls Were
Not Adequate
|
In
addition to logical access controls, other important controls should be in place
to ensure the confidentiality, integrity, and reliability of an organization's
data. These information system controls include policies, procedures, and
techniques to provide appropriate segregation of duties among computer
personnel, prevent unauthorized changes to application programs, and ensure the
continuation of computer processing operations in case of unexpected
interruption. The Commerce bureaus had weaknesses in each of these areas that
heightened the risks already created by their lack of effective access controls.
|
Computer
Duties Were Not
Properly Segregated
|
A
fundamental technique for safeguarding programs and data is to segregate the
duties and responsibilities of computer personnel to reduce the risk that errors
or fraud will occur and go undetected. OMB A-130, Appendix III, requires that
roles and responsibilities be divided so that a single individual cannot subvert
a critical process. Once policies and job descriptions that support the
principles of segregation of duties have been established, access controls can
then be implemented to ensure that employees perform only compatible functions.
None
of the seven bureaus in our review had specific policies documented to identify
and segregate incompatible duties, and bureaus had assigned incompatible duties
to staff. For example, staff were performing incompatible computer operations
and security duties. In another instance, the bureau's security officer had the
dual role of also being the bureau's network administrator. These two functions
are not compatible since the individual's familiarity with system security could
then allow him or her to bypass security controls either to facilitate
performing administrative duties or for malicious purposes.
Furthermore,
none of the bureaus reviewed had implemented processes and procedures to
mitigate the increased risks of personnel with incompatible duties.
Specifically, none of the bureaus had a monitoring process to ensure appropriate
segregation of duties, and management did not review access activity. Until
Commerce restricts individuals from performing incompatible duties and
implements compensating access controls, such as supervision and review,
Commerce’s sensitive information will face increased risks of improper
disclosure, inadvertent or deliberate misuse, and deletion, all of which could
occur without detection.
Software
Changes Were Not Adequately Controlled
|
Also
important for an organization's information security is ensuring that only
authorized and fully tested software is placed in operation. To make certain
that software changes are needed, work as intended, and do not result in the
loss of data and program integrity, such changes should be documented,
authorized, tested, and independently reviewed. Federal guidelines emphasize the
importance of establishing controls to monitor the installation of and changes
to software to ensure that software functions as expected and that a historical
record is maintained of all changes.
We
have previously reported on Commerce's lack of policies on software change
controls.
Specific key controls not addressed were (1) operating system software changes,
monitoring, and access and (2) controls over application software libraries
including access to code, movement of software programs, and inventories of
software. Moreover, implementation was delegated to the individual bureaus,
which had not established written policies or procedures for managing software
changes.
Only
three of the seven bureaus we reviewed mentioned software change controls in
their system security plans, while none of the bureaus had policies or
procedures for controlling the installation of software. Such policies are
important in order to ensure that software changes do not adversely affect
operations or the integrity of the data on the system. Without proper software
change controls, there are risks that security features could be inadvertently
or deliberately omitted or rendered inoperable, processing irregularities could
occur, or malicious code could be introduced.
|
Service
Continuity Planning Was Incomplete
|
Organizations
must take steps to ensure that they are adequately prepared to cope with a loss
of operational capability due to earthquakes, fires, sabotage, or other
disruptions. An essential element in preparing for such catastrophes is an
up-to-date, detailed, and fully tested recovery plan that covers all key
computer operations. Such a plan is critical for helping to ensure that
information system operations and data can be promptly restored in the event of
a service disruption. OMB Circular A-130, Appendix III, requires that agency
security plans assure that there is an ability to restore service sufficient to
meet the minimal needs of users. Commerce policy also requires a backup or
alternate operations strategy.
The
Commerce bureaus we reviewed had not developed comprehensive plans to ensure the
continuity of service in the event of a service disruption. Described below are
examples of service continuity weaknesses we identified at the seven Commerce
bureaus.
·
None of the seven bureaus had completed recovery
plans for all of their sensitive systems.
·
Although one bureau had developed two recovery
plans, one for its data center and another for its software development
installation center, the bureau did not have plans to cover disruptions to the
rest of its critical systems, including its local area network.
·
Systems at six of the seven bureaus did not have
documented backup procedures.
·
One bureau stated that it had an agreement with
another Commerce bureau to back it up in case of disruptions; however, this
agreement had not been documented.
·
One bureau stated in its backup strategy that tapes
used for system recovery are neither stored off-site nor protected from
destruction. For example, backup for its network file servers is kept in a file
cabinet in a bureau official's supply room, and backup tapes for a database and
web server are kept on the shelf above the server. In case of a destructive
event, the backups could be subject to the same damage as the primary files.
·
Two bureaus had no backup facilities for key network
devices such as firewalls.
Until
each of the Commerce bureaus develops and fully tests comprehensive recovery
plans for all of its sensitive systems, there is little assurance that in the
event of service interruptions, many functions of the organization will not
effectively cease and critical data will be lost.
|
Poor
Incident Detection and Response Capabilities Further Impair Security
|
As
our government becomes increasingly dependent on information systems to support
sensitive data and mission critical operations, it is essential that agencies
protect these resources from misuse and disruption. An important component of
such protective efforts is the capability to promptly identify and respond to
incidents of attempted system intrusions. Agencies can better protect their
information systems from intruders by developing formalized mechanisms that
integrate incident handling functions with the rest of the organizational
security infrastructure. Through such mechanisms, agencies can address how to
(1) prevent intrusions before they occur, (2) detect intrusions as they occur,
(3) respond to successful intrusions, and (4) report intrusions to staff and
management.
Although
essential to protecting resources, Commerce bureau incident handling
capabilities are inadequate in preventing, detecting, responding to, and
reporting incidents. Because the bureaus have not implemented comprehensive and
consistent incident handling capabilities, decision-making may be haphazard when
a suspected incident is detected, thereby impairing responses and reporting.
Thus, there is little assurance that unauthorized attempts to access sensitive
information will be identified and appropriate actions taken in time to prevent
or minimize damage. Until adequate incident detection and response capabilities
are established, there is a greater risk that intruders could be successful in
copying, modifying, or deleting sensitive data and disrupting essential
operations.
|
Incident
Handling Mechanisms Have Not Been Established or Implemented
|
Accounting
for and analyzing computer security incidents are effective ways for
organizations to better understand threats to their information systems. Such
analyses can also pinpoint vulnerabilities that need to be addressed so that
they will not be exploited again. OMB Circular A-130,
Appendix III, requires agencies to establish formal incident response mechanisms
dedicated to evaluating and responding to security incidents in a manner that
protects their own information and helps to protect the information of others
who might be affected by the incident. These formal incident response mechanisms
should also share information concerning common vulnerabilities and threats
within the organization as well as with other organizations. By establishing
such mechanisms, agencies help to ensure that they can more effectively
coordinate their activities when incidents occur.
Although
the Commerce CIO issued a July 1999 memorandum to all bureau CIOs outlining how
to prevent, detect, respond to, and report incidents, the guidance has been
inconsistently implemented. Six of
the seven bureaus we reviewed have only ad hoc processes and procedures for
handling incidents. None have established and implemented all of the
requirements of the memo. Furthermore, Commerce does not have a centralized
function to coordinate the handling of incidents on a
departmentwide
basis.
|
Incidents
Could Be Prevented
|
Two
preventive measures for deterring system intrusions are to install
(1) software updates to correct known vulnerabilities and (2) messages warning
intruders that their activities are punishable by law. First, federal guidance,
industry advisories, and best practices all stress the importance of installing
updated versions of operating system and the software that supports system
operations to protect against vulnerabilities that have been discovered in
previously released versions. If new versions have not yet been released,
“patches” that fix known flaws are often readily available and should be
installed in the interim. Updating operating systems and other software to
correct these vulnerabilities is important because once vulnerabilities are
discovered, technically sophisticated hackers write scripts to exploit them and
often post these scripts to the Internet for the widespread use of lesser
skilled hackers. Since these scripts are easy to use, many security breaches
happen when intruders take advantage of vulnerabilities for which patches are
available but system administrators have not applied the patches. Second, Public
Law 99-74 requires that a warning message be displayed upon access to all
federal computer systems notifying users that unauthorized use is punishable by
fines and imprisonment. Not only does the absence of a warning message fail to
deter potential intruders, but, according to the law, pursuing and prosecuting
intruders is more difficult if they have not been previously made fully aware of
the consequences of their actions.
Commerce has not fully instituted these two key measures to
prevent incidents. First, many bureau systems do not have system software that
has been updated to address known security exposures.
For example, during our review, we discovered 20 systems with known
vulnerabilities for which patches were available but not installed. Moreover,
all the bureaus we reviewed were still running older versions software used on
critical control devices that manage network connections. Newer versions of
software are available that correct the known security flaws of the versions
that were installed. Second, in performing our testing of network security, we
observed that warning messages had not been installed for several network paths
into Commerce systems that we tested.
Incident
Detection Capabilities Have Not Been Implemented
|
Even
though strong controls may not block all intrusions, organizations can reduce
the risks associated with such events if they take steps to detect intrusions
and the consequent misuse before significant damage can be
done. Federal guidance emphasizes the
importance of using detection systems to protect systems from the threats
associated with increasing network connectivity and reliance on information
systems. Additionally, federally funded activities, such as CERT/CC, the
Department of Energy's Computer Incident Advisory Capability, and FedCIRC are
available to assist organizations in detecting and responding to incidents.
Although
the CIO’s July memo directs Commerce bureaus to monitor their information
systems to detect unusual or suspicious activities, all the bureaus we reviewed
were either not using monitoring programs or had only partially implemented
their capabilities. For example, only two of the bureaus had installed intrusion
detection systems. Also, system and network logs frequently had not been
activated or were not reviewed to detect possible unauthorized activity.
Moreover, modifications
to critical operating system components were not logged, and security reports
detailing access to sensitive data and resources were not sent to data owners
for their review.
The
fact that bureaus we reviewed detected our activities only four times during the
2 months that we performed extensive external testing of Commerce networks,
which included probing over 1,000 system devices, indicates that, for the most
part, they are unaware of intrusions. For example, although we spent several
weeks probing one bureau's networks and obtained access to many of its systems,
our activities were never detected. Moreover, during testing we identified
evidence of hacker activity that Commerce had not previously detected. Without
monitoring their information systems, the bureaus cannot
·
know how, when,
and who performs specific computer activities,
·
be aware of
repeated attempts to bypass security, or
·
detect
suspicious patterns of behavior such as two users with the same ID and password
logged on simultaneously or users with system administrator privileges logged on
at an unexpected time of the day or night.
As
a result, the bureaus have little assurance that potential intrusions will be
detected in time to prevent or, at least, minimize damage.
|
Incident
Response
Procedures Have Not
Been Established
|
The
CIO's July memo also outlines how the bureaus are to respond to detected
incidents. Instructions include responses such as notifying appropriate
officials, deploying an on-site team to survey the situation, and isolating the
attack to learn how it was executed.
Only
one of the seven bureaus reviewed has documented response procedures.
Consequently, we experienced inconsistent responses when our testing was
detected. For example, one bureau responded to our scanning of their systems by scanning ours in
return.
In another bureau, a Commerce employee who detected our testing responded by
launching a software attack against our systems. In neither case was bureau
management previously consulted or informed of these responses.
The
lack of documented incident response procedures increases the risk of
inappropriate responses. For example, employees could
·
take no action,
·
take
insufficient actions that fail to limit potential damage,
·
take overzealous
actions that unnecessarily disrupt critical operations, or
·
take actions,
such as launching a retaliatory attack, that could be considered improper.
|
Bureaus
Have Not Been Reporting Incidents
|
The
CIO's July memo specifically requires bureau employees who suspect an incident
or violation to contact their supervisor and the bureau security officer, who
should report the incident to the department's information security manager.
Reporting detected incidents is important because this information provides
valuable input for risk assessments, helps in prioritizing security improvement
efforts, and demonstrates trends of threats to an organization as a whole.
The
bureaus we reviewed have not been reporting all detected incidents. During our
2-month testing period, 16 incidents were reported by the seven bureaus
collectively, 10 of which were generated to report computer viruses. Four of the
other six reported incidents related to our testing activities, one of which was
reported after our discovery of evidence of a successful intrusion that Commerce
had not previously detected and reported. However, we observed instances of
detected incidents that were not reported to bureau security officers or the
department's information security manager. For example, the Commerce employees
who responded to our testing by targeting our systems in the two instances
discussed above did not report either of the two incidents to their own bureau's
security officer.
By
not reporting incidents, the bureaus lack assurance that identified security
problems have been tracked and eliminated and the targeted system restored and
validated. Furthermore, information about incidents could be valuable to other
bureaus and assist the department as a whole to recognize and secure systems
against general patterns of intrusion.
|
Commerce
Does Not
Have An Effective Information
Security Management
Program
|
The
underlying cause for the numerous weaknesses we identified in bureau information
system controls is that Commerce does not have an effective departmentwide
information security management program in place to ensure that sensitive data
and critical operations receive adequate attention and that the appropriate
security controls are implemented to protect them. Our study of security
management best practices, as summarized in our 1998 Executive
Guide,
found that leading organizations manage their information security risks through
an ongoing cycle of risk management. This management process involves
(1) establishing a centralized management function to coordinate the continuous
cycle of activities while providing guidance and oversight for the security of
the organization as a whole, (2) identifying and assessing risks to determine
what security measures are needed, (3) establishing and implementing policies
and procedures that meet those needs,
(4) promoting security awareness so that users understand the risks and the
related policies and procedures in place to mitigate those risks, and
(5) instituting an ongoing monitoring program of tests and evaluations to ensure
that policies and procedures are appropriate and effective. However, Commerce's
information security management program is not effective in any of these key
elements.
|
Centralized
Management
Is Weak
|
Establishing
a central management function is the starting point of the information security
management cycle mentioned above. This function provides knowledge and expertise
on information security and coordinates organizationwide security-related
activities associated with the other four segments of the risk management cycle.
For example, the function researches potential threats and vulnerabilities,
develops and adjusts organizationwide policies and guidance, educates users
about current information security risks and the policies in place to mitigate
those risks, and provides oversight to review compliance with policies and to
test the effectiveness of controls. This central management function is
especially important to managing the increased risks associated with a highly
connected computing environment. By providing coordination and oversight of
information security activities organizationwide, such a function can help
ensure that weaknesses in one unit's systems do not place the entire
organization's information assets at undue risk.
According
to Commerce policy, broad program responsibility for information security
throughout the department is assigned to the CIO. Department of Commerce
Organization Order 15-23 of July 5, 2000, specifically tasks the CIO with
developing and implementing the department's information security program to
assure the confidentiality, integrity, and availability of information and IT
resources. These responsibilities include developing policies, procedures, and
directives for information security; providing mandatory periodic training in
computer security awareness and accepted practice; and identifying and
developing security plans for Commerce systems that contain sensitive
information. Furthermore, the CIO is also formally charged with carrying out the
Secretary's responsibilities for computer security under OMB Circular A-130,
Appendix III for all Commerce bureaus and the Office of the Secretary.
An
information security manager under the direction of the Office of the CIO is
tasked with carrying out the responsibilities of the security program. These
responsibilities, which are clearly defined in department policy, include
developing security policies, procedures, and guidance and assuring security
oversight through reviews, which include tracking the implementation of required
security controls.
Commerce
lacks an effective centralized function to facilitate the integrated management
of the security of its information system infrastructure. At the time of our
review, the CIO, who had no specific budget to fulfill security responsibilities
and exercised no direct control over the IT budgets of the Commerce bureaus,
stated that he believed that he did not have sufficient resources or the
authority to implement the department information security program. Until
February 2000, when additional staff positions were established to support the
information security manager’s responsibilities, the information security
manager had no staff to discharge these tasks. As of April 2001, the information
security program was supported by a staff of three.
Commerce
policy also requires each of its bureaus to implement an information security
program that includes a full range of security responsibilities. These include
appointing a bureauwide information security officer as well as security
officers for each of the bureau's systems.
However,
the Commerce bureaus we reviewed also
lack their own centralized functions to coordinate bureau security programs
with departmental policies and procedures and to implement effective programs
for the security of the bureaus' information systems infrastructure. For
example, four bureaus had staff assigned to security roles on a part-time basis
and whose security responsibilities were treated as collateral duties.
In
view of the widespread interconnectivity of Commerce's systems, the lack of a
centralized approach to the management of security is particularly risky since
there is no coordinated effort to ensure that minimal security controls are
implemented and effective across the department. As demonstrated by our testing,
intruders who succeeded in gaining access to a system in a bureau with weak
network security could then circumvent the stronger network security of other
bureaus. It is, therefore, unlikely that the security posture of the department
as a whole will significantly improve until a more integrated security
management approach is adopted and sufficient resources allotted to implement
and enforce essential security measures departmentwide.
As
outlined in our 1998 Executive Guide, understanding the risks associated with
information security is the second key element of the information security
management cycle. Identifying and assessing information security risks helps to
determine what controls are needed and what level of resources should be
expended on controls. Federal guidance requires all federal agencies to develop
comprehensive information security programs based on assessing and managing
risks.
Commerce policy regarding information security requires (1) all bureaus to
establish and implement a risk management process for all IT resources and (2)
system owners to conduct a periodic risk analysis for all sensitive systems
within each bureau.
Commerce
bureaus we reviewed are not conducting risk assessments for their sensitive
systems as required. Only 3 of the bureaus' 94 systems we reviewed
had documented risk assessments, one of which was still in draft. Consequently,
most of the bureaus' systems are being operated without consideration of the
risks associated with their immediate environment.
Moreover,
these bureaus are not considering risks outside their immediate environment that
affect the security of their systems, such as network interconnections with
other systems. Although OMB Circular A-130, Appendix III, specifically requires
that the risks of connecting to other systems be considered prior to doing so,
several bureau officials acknowledged that they had not considered how
vulnerabilities in systems that interconnected with theirs could undermine the
security of their own systems. Rather, the initial decision to interconnect
should have been made by management based on an assessment of the risk involved,
the controls in place to mitigate the risk, and the predetermined acceptable
level of risk. The widespread lack of risk assessments, as evidenced by the
serious access control weaknesses revealed during our testing, indicates that
Commerce is doing little to understand and manage risks to its systems.
Security
Plans Are Not Prepared
Once
risks have been assessed, OMB Circular A-130, Appendix III, requires agencies to
document plans to mitigate these risks through system security plans. These
plans should contain an overview of a system's security requirements; describe
the technical controls planned or in place for meeting those requirements;
include rules that delineate the responsibilities of managers and individuals
who access the system; and outline training needs, personnel controls, and
continuity plans. In summary, security plans should be updated regularly to
reflect significant changes to the system as well as the rapidly changing
technical environment and document that all aspects of security for a system
have been fully considered, including management, technical, and operational
controls.
None
of the bureaus we reviewed had security plans for all of their sensitive
systems. Of the 94 sensitive systems we reviewed, 87 had no security plans. Of
the seven systems that did have security plans, none had been approved by
management. Moreover, five of these seven plans did not include all the elements
required by OMB Circular A-130, Appendix III. Without comprehensive security
plans, the bureaus have no assurance that all aspects of security have been
considered in determining the security requirements of the system and that
adequate protection has been provided to meet those requirements.
Systems
Are Not Authorized
OMB
also requires management officials to formally authorize the use of a system
before it becomes operational, when a significant change occurs, and at least
every 3 years thereafter.
Authorization provides quality control in that it forces managers and technical
staff to find the best fit for security, given technical constraints,
operational constraints, and mission requirements. By formally authorizing a
system for operational use, a manager accepts responsibility for the risks
associated with it. Since the security plan establishes the system protection
requirements and documents the security controls in place, it should form the
basis for management's decision to authorize processing.
As
of March 2001, Commerce management had not authorized any of the 94 sensitive
systems that we identified. According to the more comprehensive data collected
by the Office of the CIO in March 2000, 92 percent of all the department's
sensitive systems had not been formally authorized. The lack of authorization
indicates that systems' managers had not reviewed and accepted responsibility
for the adequacy of the security controls implemented on their systems. As a
result, Commerce has no assurance that these systems are being adequately
protected.
|
Needed
Policies Have Not Been Established
|
The
third key element of computer security management, as identified during our
study of information security management practices at leading organizations, is
establishing and implementing policies. Security policies are important because
they are the primary mechanism by which management communicates its goals and
requirements. Federal guidelines require agencies to frequently update their
information security policies in order to assess and counter rapidly evolving
threats and vulnerabilities.
Commerce's
information security policies are significantly outdated and incomplete.
Developed in 1993 and partially revised in 1995, the department's information
security policies and procedures manual, Information
Technology Management Handbook, Chapter 10, “Information Technology
Security,” and attachment, “Information Technology Security” does not
comply with OMB’s February 1996 revision to Circular A-130, Appendix III, and
does not incorporate more recent NIST guidelines. For example, Commerce’s
information security policy does not reflect current federal requirements for
managing computer security risk on a continuing basis, authorizing processing,
providing security awareness training, or performing system reviews. Moreover,
because the policy was written before the explosive growth of the Internet and
Commerce’s extensive use of it, policies related to the risks of current
Internet usage are omitted. For example, Commerce has no departmentwide security
policies on World Wide Web sites, e-mail, or networking.
Further,
Commerce has no departmental policies establishing baseline security
requirements for all systems. For example, there is no departmental policy
specifying required attributes for passwords, such as minimum length and the
inclusion of special characters. Consequently, security settings differ both
among bureaus and from system to system within the same bureau. Furthermore,
Commerce lacks consistent policies establishing a standard minimum set of access
controls. Having these baseline agencywide policies could eliminate many of the
vulnerabilities discovered by our testing, such as configurations that provided
users with excessive access to critical system files and sensitive data and
expose excessive system information, all of which facilitate intrusions.
The
Director of the Office of Information Policy, Planning, and Review and the
Information Security Manager stated that Commerce management recognizes the need
to update the department information security policy and will begin updating the
security sections of the Information
Technology Management Handbook in the immediate future.
|
Security
Awareness and
Training Are Not Adequately Promoted
|
The
fourth key element of the security management cycle involves promoting awareness
and conducting required training so that users understand the risks and the
related policies and controls in place to mitigate them. Computer intrusions and
security breakdowns often occur because computer users fail to take appropriate
security measures. For this reason, it is vital that employees who use computer
systems in their day-to-day operations are aware of the importance and
sensitivity of the information they handle, as well as the business and legal
reasons for maintaining its confidentiality, integrity, and availability.
OMB
Circular A-130, Appendix III, requires that employees be trained on how to
fulfill their security responsibilities before being allowed access to sensitive
systems. The Computer Security Act mandates that all federal employees and
contractors who are involved with the management, use, or operation of federal
computer systems be provided periodic training in information security awareness
and accepted information security practice. Specific training requirements are
outlined in NIST guidelines,
which establish a mandatory baseline of training in security concepts and
procedures and define additional structured training requirements for personnel
with security-sensitive responsibilities.
Overall,
none of the seven bureaus had documented computer security training procedures
and only one of the bureaus had documented its policy for such training. This
bureau also used a network user responsibility agreement, which requires that
all network users read and sign a one-page agreement describing the network
rules. Officials at another bureau stated that they were developing a security
awareness policy document.
Although
each of the seven bureaus had informal programs in place, such as a brief
overview as part of the one-time general security orientation for new employees,
these programs do not meet the requirements of OMB, the Computer Security Act,
or NIST Special Publication 800-16. Such brief overviews do not ensure that
security risks and responsibilities are understood by all managers, users, and
system administrators and operators. Shortcomings in the bureaus' security
awareness and training activities are illustrated by the following examples.
·
Officials at one bureau told us that they did not
see training as an integral part of its security program, and provided an
instructional handbook only to users of a specific bureau application.
·
Another bureau used a generic computer-based
training course distributed by the Department of Defense that described general
computer security concepts but was not specific to Commerce's computing
environment. Also, this bureau did not maintain records to document who had
participated.
·
Another bureau had limited awareness practices in
place such as distribution of a newsletter to staff, but had no regular training
program. Officials at this bureau told us that they were in the process of
assessing its training requirements.
Only
one Commerce bureau that we reviewed provided periodic refresher training. In
addition, staff directly responsible for information security do not receive
more extensive training than overviews since security is not considered to be a
full-time function requiring special skills and knowledge. Several of the
computer security weaknesses we discuss in this testimony indicate that Commerce
employees are either unaware of or insensitive to the need for important
information system controls.
|
Policies
and Controls Are
Not Monitored
|
The
final key element of the security management cycle is an ongoing program of
tests and evaluations to ensure that systems are in compliance with policies and
that policies and controls are both appropriate and effective. This type of
oversight is a fundamental element because it demonstrates management’s
commitment to the security program, reminds employees of their roles and
responsibilities, and identifies and corrects areas of noncompliance and
ineffectiveness. For these reasons, OMB Circular A-130, Appendix III, directs
that the security controls of major information systems be independently
reviewed or audited at least every 3 years. Commerce policy also requires
information security program oversight and tasks the program manager with
performing compliance reviews of the bureaus as well as verification reviews of
individual systems. The government information security reform provisions of the
fiscal year 2001 National Defense Authorization Act require annual independent
reviews of IT security in fiscal years 2001 and 2002.
No
oversight reviews of the Commerce bureaus' systems have been performed by the
staff of Commerce's departmentwide information security program. The information
security manager stated that he was not given the resources to perform these
functions. Furthermore, the bureaus we reviewed do not monitor the effectiveness
of their information security. Only one of the bureaus has performed isolated
tests of its systems. In lieu of independent reviews, in May 2000, the Office of
the CIO, using a draft of the CIO Council's Security Assessment Framework,
requested that all Commerce bureaus submit a self-assessment of the security of
their systems based on the existence of risk assessments, security plans, system
authorizations, awareness and training programs, service continuity plans, and
incident response capabilities. This self-assessment did not require testing or
evaluating whether systems were in compliance with policies or the effectiveness
of implemented controls. Nevertheless, the Office of the CIO’s analysis of the
self-assessments showed that 92 percent of Commerce's sensitive systems did not
comply with federal security requirements. Specifically, 63 percent of
Commerce's systems did not have security plans that comply with federal
guidelines, 73 percent had no risk assessments, 64 percent did not have recovery
plans, and 92 percent had not been authorized for operational use.
The
information security manager further stated that, because of the continued lack
of resources, the Office of the CIO would not be able to test and evaluate the
effectiveness of Commerce's information security controls to comply with the
government information security reform provisions requirement of the fiscal year
2001 National Defense Authorization Act. Instead, the information security
manager stated that he would again ask the bureaus to do another self-assessment
and would analyze the results. In future years, the information security manager
intends to perform hands-on reviews as resources permit.

In
conclusion, Mr. Chairman, the significant and pervasive weaknesses that we
discovered in the seven Commerce bureaus we tested place the data and operations
of these bureaus at serious risk. Sensitive economic, personnel, financial, and
business confidential information are exposed, allowing potential intruders to
read, copy, modify, or delete these data. Moreover, critical operations could
effectively cease in the event of accidental or malicious service disruptions.
Poor
detection and response capabilities exacerbate the bureaus' vulnerability to
intrusions. As demonstrated during our own testing, the bureaus' general
inability to notice our activities increases the likelihood that intrusions will
not be detected in time to prevent or minimize damage.
These
weaknesses are attributable to the lack of an effective information security
program, that is, lack of centralized management, a risk-based approach,
up-to-date security policies, security awareness and training, and continuous
monitoring of the bureaus' compliance with established policies and the
effectiveness of implemented controls. These weaknesses are exacerbated by
Commerce's highly interconnected computing environment in which the
vulnerabilities of individual systems affect the security of systems in the
entire department, since a compromise in a single poorly secured system can
undermine the security of the multiple systems that connect to it.
To
address these weaknesses, we are recommending that the Secretary
·
direct the Office of the CIO and the bureaus to
develop and implement an action plan for strengthening access controls for
Commerce's systems commensurate with the risk and magnitude of the harm
resulting from the loss, misuse, or modification of information resulting from
unauthorized access. Specifically, this action plan should address the logical
access control weaknesses and other information system weaknesses that are
summarized in our draft report,
·
direct the Office of the CIO to establish a
departmentwide incident handling function with formal procedures for preparing
for, detecting, responding to, and
reporting incidents, and
·
direct the Office of the CIO to develop and
implement an effective departmentwide security program.
Such a program should include establishing a central information security
function to manage an ongoing cycle of the following security activities:
-
assessing risks and evaluating needs,
-
updating the information security program policies,
-
developing and implementing a computer security
awareness and training program, and
-
developing and implementing a management oversight
process that includes periodic compliance reviews and tests of the effectiveness
of implemented controls.
We
also recommend that the Secretary of Commerce, the Office of the CIO, and the
bureau CIOs direct the appropriate resources and authority to fulfill the
security responsibilities that Commerce policy and directives task them with
performing and to implement these recommendations.
We
also recommend that the Secretary take advantage of the opportunity that the
installation of the new network infrastructure will provide to improve security.
Mr.
Chairman, this concludes my statement. I would be pleased to respond to any
questions that you or other members of the Committee may have at this time.

Firewalls are hardware and software components that protect
one set of system resources (e.g., computers and networks) from attack by
outside network users (e.g., Internet users) by blocking and checking all
incoming network traffic. Firewalls permit authorized users to access and
transmit privileged information and deny access to unauthorized users.
