Hearing on Veterans Benefits Administration Data Security
June 20, 2006
Chairman Miller, Chairman Boozman, and
Members of the Subcommittees, thank you for the opportunity to testify
today concerning the Office of Inspector General’s (OIG) reports
addressing information security weaknesses in the Department of Veterans
Affairs (VA) and data security practices and policies in the Veterans
Benefits Administration (VBA). I will provide a general overview of our
work in this area and then focus on specific issues involving VBA. In
preparing this testimony, we drew on previous reports related to VA’s
Consolidated Financial Statements (CFS) audits since fiscal year (FY)
1997, Federal Information Security Management Act (FISMA) reviews since
FY 2001, and security weaknesses and vulnerabilities at VA regional
offices where security issues were evaluated during our Combined
Assessment Program (CAP) reviews since FY 2000. All of these findings
impact on VBA.
EXECUTIVE SUMMARY
For many years, significant concerns have been raised about VBA’s
information security. As part of the CFS audit, information technology
(IT) security controls have been reported as a material weakness. We
have reported that program and financial data are at risk due to serious
problems related to control and oversight of access to information
systems. We have reported segregation of duties, service continuity, and
change controls need to be strengthened. Our FISMA reviews highlight
specific vulnerabilities that can be exploited, but the recurring themes
in these reports are the need for centralization, remediation, and
accountability in VA information security. Since the FY 2001 report, we
reported weaknesses in physical security, electronic security, and FISMA
reporting, and since 2002, we also reported weaknesses in wireless
security and personnel security. In addition to our CFS audits and FISMA
reviews, our CAP reviews disclosed IT and security deficiencies at 37
(67 percent) of 55 VBA facilities reviewed. To ensure that security
issues identified during audits and reviews were adequately addressed,
we recommended that VA pursue a more centralized approach, apply
appropriate resources, and establish a clear chain of command and
accountability structure to implement and enforce IT internal controls.
Consolidated Financial Statement Audits Continue to Report
Information Security as a Material Weakness
Pursuant to the Chief Financial Officers Act of 1990, the VA
consolidated financial statements are audited annually. We contract with
an independent public accounting firm to perform this audit. The
contractor follows Government Accountability Office methodology to
assess the effectiveness of computer controls at VA’s three information
technology centers (ITCs) and selected regional offices and medical
centers.
As part of the CFS audit, IT security controls have been reported as a
material weakness for many years. A material weakness is defined as a
weakness in internal control that could have a material effect on the
financial statements and not be detected by employees in the normal
course of their business. We have reported that VA’s program and
financial data are at risk due to serious problems related to VA’s
control and oversight of access to its information systems. For example,
by not controlling and monitoring employee access, not restricting users
to only need-to-know data, and not timely terminating accounts upon
employee departure, VA has not mitigated the potential risk. These
conditions place sensitive information, including financial data and
sensitive veteran medical and benefit information, at risk, possibly
without detection of inadvertent or deliberate misuse, fraudulent use,
improper disclosure, or destruction.
As a result of these vulnerabilities, we recommended that VA pursue a
more centralized approach, apply appropriate resources, and establish a
clear chain of command and accountability structure to implement and
enforce IT internal controls. We also recommended that VA continue its
efforts to accomplish the following key tasks:
• Improve access control policies and procedures for configuring
security settings on operating systems, improve administration of user
access, and detect and resolve potential access violations.
• Evaluate user functional access needs and system access privileges to
support proper segregation of duties within financial applications.
Assign, communicate, and coordinate responsibility for enforcing and
monitoring such controls consistently throughout VA.
• Develop a service continuity plan at the departmental level that will
facilitate effective communication and implementation of overall
guidance and standards, and provide coordination of VA’s service
continuity effort. Schedule and adequately test IT disaster recovery
plans to ensure continuity of operations in the event of a disruption of
service.
• Develop a change control framework and, within that framework,
implement application specific change control procedures for mission
critical systems.
VA has implemented some recommendations for specific locations
identified but has not made corrections VA-wide. For example, we found
violations of password policies which management immediately corrected,
but in following years, we found similar violations at other facilities.
We also found instances of terminated or separated employees with access
to critical systems identified at various locations which management
corrected, only to discover similar instances elsewhere.
Annual Evaluations of VA’s Information Security Program Have
Identified Vulnerabilities that Remain Uncorrected
FISMA requires us to annually review the progress of the information
technology and security program of the Department and report the results
to the Office of Management and Budget (OMB). As part of the FISMA
review, we conduct scanning and penetration tests of selected VA systems
to assess controls for monitoring and accessing systems, and reviews of
physical, personnel, and electronic security. We visit the three major
IT centers and selected regional offices and medical centers in addition
to IT work on financial statements.
In all four audits of the VA Information Security Program issued since
2001, we reported vulnerabilities that continue to need management
attention. These reports highlight specific vulnerabilities that can be
exploited, but the recurring themes in these reports are the need for
centralization, remediation, and accountability in VA information
security. Since the FY 2001 report, we reported weaknesses in physical
security, electronic security, and FISMA reporting, and since 2002, we
also reported weaknesses in wireless security and personnel security.
Additionally, we have reported significant issues with implementation of
security initiatives VA-wide. The status of unimplemented
recommendations was discussed in subsequent audits.
The FY 2004 audit also emphasized the need to centralize the IT security
program, implement security initiatives, and close security
vulnerabilities. We previously recognized that the Office of the
Assistant Secretary for Information and Technology/Chief Information
Officer’s (CIO’s) office needed to be fully staffed, and that funding
delays and resistance by offices to relinquish their own security
functions and activities delayed implementation of the fully centralized
CIO contemplated by our prior recommendations. The CIO’s comments to the
report referenced an April 2004 VA General Counsel opinion that held the
CIO lacked the authority to enforce compliance with the VA information
security program as one reason he could not address vulnerabilities. We
again recommended that VA fully implement and fund a centralized VA-wide
IT security program.
In total, the FY 2004 report included 16 recommendations: (1) centralize
IT security programs; (2) implement an effective patch management
program; (3) address security vulnerabilities of unauthorized access and
misuse of sensitive information and data throughout VA demonstrated
during OIG field testing; (4) ensure position descriptions contain
proper data access classification; (5) obtain timely, complete
background investigations; and complete the following security
initiatives on (6) intrusion detection systems, (7) infrastructure
protection actions, (8) data center contingency planning, (9)
certification and accreditation of systems, (10) upgrading/terminating
external connections, (11) improvement of configuration management, (12)
moving VA Central Office (VACO) data center, (13) improvement of
application program/operating system change controls, (14) limiting
physical access to computer rooms, (15) wireless devices, and (16)
electronic transmission of sensitive veteran data. As of June 19, 2006,
all recommendations from this report remain open.
CAP Reviews Show Information System Security Vulnerabilities Continue
to Exist
We continue to identify instances where out-based employees send
veterans’ medical information to the VA regional office via unencrypted
e-mail; system access for separated employees is not terminated;
monitoring remote network access and usage does not routinely occur; and
off duty users’ access to VA computer systems and sensitive information
is not restricted. We continue to make recommendations to improve
security and contingency plans, control access to information systems,
complete background investigations and annual security awareness
training, and improve physical security controls.
While individual and regional managers have concurred with these CAP
recommendations, and our follow-up process confirms actions to resolve
the specific conditions identified at these sites, we continue to find
that corrective actions are not applied to all facilities to correct
conditions nationwide. Consequently, we continue to find these systemic
conditions at other sites we visit. For example, between FYs 2000 to
2005, we identified IT and security deficiencies at 37 (67 percent) of
55 VBA facilities reviewed.
IT Security Remains a Major Management Challenge
The OIG annually summarizes the most serious management problems
identified during reviews. We have identified information security and
security of data and data systems in all major management challenge
reports issued since FY 2000. The major management challenges are
published in VA’s annual Performance and Accountability Report.
STATUS OF CURRENT FISMA RECOMMENDATIONS
We have recently issued an advance copy our of FY 2005 FISMA draft
report to the Department. We restructured the draft report to respond to
the Department’s comments and announced reorganization actions designed
to implement centralization in the CIO’s office. While the OIG does not
release draft reports, because of the extensive public interest in these
issues resulting from the recent data loss incident involving the
burglary of a VA data analyst’s home, I would like to summarize the
findings and recommendations of this report.
VA is still in the process of addressing recommendations made during
prior FISMA audits to improve IT operations and controls. We have one
additional recommendation for an existing area that needs to be elevated
for priority attention. VA has made progress during FY 2005 to improve
IT controls and to implement some recommendations. For example, after
the FY 2005 testing was finished, VA informed us that certification and
accreditation reviews have been completed and the deployment of
intrusion detection systems (IDS) has been accomplished. We will
validate implementation in future annual FISMA audits.
I will discuss in greater detail the 16 issues and discuss 1 new issue,
as well as our recommendations for corrective actions.
Issue 1: Implementation of a Centralized Agency-wide IT Security Program
The CIO is VA’s focal point for IT topics. Although the CIO is
responsible for VA’s information systems, operational controls were
decentralized among each administration within VA. The operational
control has been vested with the Veterans Health Administration (VHA),
VBA, the National Cemetery Administration (NCA), and other program
offices in VA. The CIO provided guidance and the tools to support the
activities with operational control to secure VA systems, but the CIO
did not have the ability to enforce or hold officials accountable for
non-compliance. The CIO was responsible for the general management of
all VA IT resources, including policy guidance, budgetary review, and
general oversight. However, the implementation of the information
security program was accomplished by VA personnel who were not under the
direct supervision or control of the CIO.
Recently, Congress gave VA and the CIO a unique opportunity to
centralize IT operational and maintenance activities, and to establish
and implement policies designed to standardize IT functionality within
the Department. For example, the House in November 2005 passed H.R.
4061, known as the “Department of Veterans Affairs Information
Technology Management Improvement Act of 2005.” This bill would give the
VA CIO the authority to centralize IT operations and activities
consistent with one of our open recommendations.
VA informed Congress that it plans to move towards a “federated IT
system” to realign department-wide IT operations and maintenance
responsibilities under the direct authority of the CIO. The main feature
of the realignment will place VA’s IT budget, along with IT
professionals involved in operation and maintenance work, directly under
the authority of the Assistant Secretary for Information and
Technology/CIO. However, IT employees involved in system development
will remain under their respective administrations and staff offices
(e.g., VHA, VBA, NCA, and some program offices). Given that the planned
realignment has just begun, VA’s “federated IT system” implementation
plans will need further study. For example, we will need to review
whether existing IT systems and operations under the purview of the CIO
will efficiently and effectively communicate with newly designed
applications implemented by these system development offices. Failure to
implement sound policies and procedures could introduce a significant
amount of risk into the production environment if the access controls
given to development staffs are not adequately developed and enforced.
Issue 2: Implementation of a Patch Management Program
VA continues to review and address patch management issues to find
long-term solutions. We previously identified a number of critical
patches that were either not installed or not appropriately implemented
at the VA facilities reviewed. VA did not have an enterprise-wide
solution that could directly connect to over 250,000 points within VA,
including VBA desktops on which VBA employees ran e-mail. During our FY
2005 review, VA continued to evaluate solutions to remediate this
condition. VA was still in the process of developing and fully deploying
a patch management program.
VA’s CIO identified roles and responsibilities to address VA Enterprise
Patch Management processes and standard operating procedures. A January
7, 2005, memorandum, Enterprise Patch Management, signed by the CIO,
details patch management roles, responsibilities, and special
considerations. We are continuing to follow up on the efforts taken by
VA to implement this recommendation in future audits.
Issue 3: Electronic Security
Our reviews conducted at Hines and Philadelphia ITCs, the Chicago
Regional Office, and the Philadelphia Regional Office and Insurance
Center during FY 2005 found potential vulnerabilities that we previously
identified relating to password controls, remote access, and securing
critical files. Additionally, we continued to find security
vulnerabilities related to the lack of segregation of duties; unsecured
critical files, which could allow attackers access to password files;
and inappropriate access through remote access software.
Our field work at facilities previously visited in prior years—including
the Washington, D.C, Regional Office—found potential vulnerabilities
warranting management attention. The reviews indicate that while
managers at sites visited are addressing vulnerabilities identified
during these reviews, sites not visited in prior years have not been
advised that the vulnerabilities identified may be systemic in nature.
VA needs a consistent approach at all of its facilities to effectively
monitor networks and to use tools, such as electronic scanning, to
proactively identify and correct security vulnerabilities.
Issue 4: Personnel Security
In FY 2005, we continued to find previously identified weaknesses
related to position descriptions and training of VA employees and
contractors, including those in VBA. Sensitive position descriptions
needed better documentation. We found the sensitivity rating was
inaccurate for some employee positions at facilities reviewed and that
position descriptions needed to more specifically address the levels of
access relative to the positions’ duties and responsibilities. To ensure
the integrity of the benefits program, OIG recommended that VBA
employees disclose in writing their own and their relatives’ veteran
status. We continue to identify lack of compliance with this
requirement.
Issue 5: Background Investigations
VBA needs to ensure that employee and contractor background
investigation requirements are adequately identified and addressed. In
FY 2005, we identified instances where background investigations and
reinvestigations were not initiated in a timely manner on employees and
contractors, or were not initiated at all. We will follow up on this
issue in future FISMA audits.
Issue 6: Deployment and Installation of Intrusion Detection Systems
Although much has been done, the VA’s Office of Cyber and Information
Security (OCIS) still need to validate whether VA completed installation
of IDS at all sites, including VBA sites. Deploying and installing IDS
is a key step in the process of securing VA data systems on a national
basis. Implementation of IDS increases VA’s ability to detect
intrusions. OCIS advised us that an enterprise-wide IDS has been fully
implemented. In addition, OCIS is researching the benefits of moving to
Intrusion Prevention Systems in an effort to provide VA the capability
to detect and prevent “attacks.” We will be testing the effectiveness of
the IDS system in future FISMA audits.
Issue 7: Infrastructure Protection Actions
VA needs to complete infrastructure planning efforts. During our FY 2004
audit, we found examples where the physical infrastructure had
significant vulnerabilities and did not adequately protect data from
potential destruction, manipulation, and inappropriate disclosure.
During our FY 2005 field work, we found that VA was developing a
Critical Infrastructure Protection Plan, and completed an identification
and prioritization of critical information resources. We will review
VA’s progress in completing and implementing this plan in future FISMA
audits. Specific VBA vulnerabilities include perimeter security, old
hardware, and legacy applications.
Issue 8: Information Technology Centers’ Continuity of Operations Plans
VBA is making progress and had completed Continuity of Operations (COOP)
plans but full testing needs to be done. VA has issued an Emergency
Preparedness Directive/Handbook 0320 for the VACO’s COOP. VA was
developing a Master COOP for the entire VA, which will include all
elements in the Central Office COOP. National Institute of Standards and
Technology (NIST) 800-34, Contingency Planning Guide for Information
Technology Systems, dated June 2002, recommends COOP testing should be
accomplished at least annually. COOPs covering ITCs need to ensure
capabilities exist to provide necessary operational support in the event
of disasters.
Our field tests conducted in FY 2005 showed that the ITCs have completed
these contingency plans, but that testing these plans needed to be
jointly done among all program offices residing in the ITCs. After FY
2005 field work was completed, we learned that VBA-related hardware had
been procured at one ITC to back up data, and some independent testing
has been performed. For example, VBA informed us that they recently
conducted tests at their ITCs and performed disaster recovery exercises.
While this is a step forward, joint collaborative testing by all tenant
offices within the ITCs (VHA, VBA, NCA, and other offices) would serve
as a better gauge of determining the adequacy of responses. We will
follow up on this issue in future FISMA audits.
Issue 9: Certification and Accreditation Process
During FY 2005 field work, we found that VA had placed a priority on the
uncompleted Certification and Accreditation (C&A) process. The number of
VA systems and major applications decreased from 678 in FY 2004 to 585
in FY 2005, as a result of VA combining applications or by removing
previously reported systems that did not meet the NIST criteria. VBA has
96 of the 585 systems and major applications. At the end of our field
work in the summer of 2005, VA had not completed a C&A for all systems
and major applications. The former Secretary of Veterans Affairs had
made it a priority to complete all C&A work by the end of August 2005,
and in November 2005, VA reported to OMB that it had completed a C&A for
all VA systems and major applications. We will follow up in future FISMA
audits to ensure all C&A work has been done, that self-reported
deficiencies have been identified and actions are underway to address
them, and that there is documentation to support the C&A work.
Issue 10: Terminate/Upgrade External Connections
In prior audits, we reported security risks associated with the
operation of uncertified Internet gateways that affect the entire
Department, including VBA. As of FY 2005, VA took actions to mitigate
these risks by limiting the number of Internet gateways in order to
improve control over access to VA systems.
Field work conducted in FY 2005 found that VA is still unable to
determine if all extraneous external connections have been terminated.
We are currently unsure of the extent VA and its affiliated and
non-affiliated partners may be operating their own gateways.
We also found that the standard contract VA used to procure computers
included as a standard feature, modem devices, which if retained in
default settings could serve as access points for hackers attempting to
gain entry into VA systems. A January 2005 OIG report on procurement of
desktop modems prompted VA to amend its contract and to address the
modem security vulnerabilities with all facilities. We have left this
recommendation open and will be continuing to review this issue during
future FISMA audits.
Issue 11: Configuration Management
Prior year audits have found instances where VA networks relied on old
operating systems such as Windows 95 and Windows 98, which placed the VA
networks at risk due to the lack of vendor support to upgrade security
and other features. An unsupported operating system, whether desktop or
production mainframe, exposes VA to potential security and operational
risks, including operating system failure.
During FY 2005 field work, we found VBA had reduced the number of
personal computers running Windows 95, but other aged computers must
continue to operate due to special document scanners associated with The
Imaging Management System (known as “TIMS”). We were told that these
scanners and personal computers are expected to be replaced or retired
during FY 2006, if funds are available. The System Configuration and
Management Program continues to review this issue, however, actions are
still pending completion; therefore, we will follow up on future audits.
Issue 12: Movement and Consolidation of VACO’s Data Center
We previously reported that the VACO data center was located below
ground level and experienced water damage twice in the last 10 years.
This facility houses the hardware that supports the VBA headquarters
operation. VA reported the relocation of the VACO data center is in
progress. In the interim, VA placed equipment in multiple locations
throughout the Washington, D.C., metropolitan area until procurement and
construction is completed at a new location. Even though progress has
been made, our observations identified routers and switches that support
VACO network backbone critical to their operations remain below ground
level. We will follow up on this issue in future FISMA audits.
Issue 13: Application Program/Operating System Change Controls
VA change control policy does not provide uniform application
development and change guidance for a wide range of new and legacy
applications, including VBA systems. Nationwide policy is necessary to
facilitate consistent implementation and effective monitoring of system
change controls for mission critical systems.
For example, we found changes to a mainframe operating system and
supporting hardware were not supported by local management
authorization. Additionally, we found instances where changes to the
production environment were not adequately documented or approved for
major applications and critical systems. Consequently, unauthorized
changes could have adversely affected the production environment or lead
to misuse without warning. We will continue to follow up on this issue
in future FISMA audits.
Issue 14: Physical Access Controls
At previous sites visited, VBA was attempting to make improvements to
ensure adequate measures were implemented to secure veterans’
information and provide a safe environment for employees and visitors.
However, our facility reviews at new locations showed physical access
controls still need improvement. For example, a number of facilities
granted access to computer rooms to employees who did not have a need to
be in the computer room to perform their job function, and some
contractors did not have an escort while in the computer room. We will
continue to follow up on this issue in future FISMA audits.
Issue 15: Wireless Security
VA is making progress in reducing wireless security vulnerabilities by
securing its network from outside intrusion. Actions were taken to
install an encryption wireless product that is designed to prohibit
unauthorized users from accessing the network. However, our contractor
penetration test showed some vulnerability in the wireless network could
be used to view transmissions, including location of veterans’ claims
folders, and to gain access to systems residing on VA’s internal
networks. Despite improvements, VA’s information systems remained at
risk for unauthorized access or misuse of sensitive information.
Issue 16: Encrypting Sensitive Information on VA Networks
VA has stated that it was taking interim steps to improve transmission
of protected and sensitive information over its networks as sensitive
data continues to be transmitted in clear text on VA networks. VA
informed us that installation of encryption capabilities on some of its
older platforms would render the systems inefficient. The OIG contractor
penetration team was able to access regional office files, create a
fictitious veteran, establish an award, and mail an award letter to a
real address as a trusted insider as a result of unencrypted
information. Our site work also showed that unencrypted protected
benefit information was vulnerable within VA.
Issue 17: FISMA Reporting Database
FISMA establishes security requirements and requires VA to annually
report vulnerabilities for systems and major applications. While VBA is
taking actions to address security vulnerabilities, we continue to
identify weaknesses that require a centralized and coordinated effort to
ensure corrective actions are taken to control access, to secure
computer rooms, and to ensure facilities accurately report their
security deficiencies that place VBA information and data at risk.
The FISMA database contains the self-assessment surveys of VBA’s major
applications and systems. System and application deficiencies, as well
as funded and unfunded remediation plans, are reported and stored in
this database. Consequently, this database needs to accurately
demonstrate the security posture of VBA’s systems and major
applications. Also, it should accurately depict the risk of loss of the
critical and sensitive information contained within these systems and
major applications.
Comparisons of the sites visited to the entries in the FISMA database
found that not all information was accurate or complete. Most
inaccuracies involved reporting of the five levels of IT security
program effectiveness outlined in the Federal Information Technology
Security Assessment Framework. Additionally, facilities were not held
accountable for information inaccuracies or incomplete data in the
database. For example, fields requiring information pertaining to the
amount of funding needed to correct deficiencies were incomplete. VBA
senior leadership needs this information to determine the costs to
correct the conditions identified. With inaccurate or incomplete
information in the FISMA database, VA senior leadership will not have a
complete picture of VA’s information security posture and the level of
resources and funding needed to remediate security deficiencies.
RECOMMENDATIONS
We recommended that the Acting Assistant Secretary for Information and
Technology/CIO, in conjunction with senior VA leadership, take actions
to fully address all 17 issues summarized above.
CLOSING
In closing, I would like the Subcommittees to know that reviews of VA’s
information security will remain a priority for the OIG until these
issues are resolved. We remain committed to following up and continuing
to assess the adequacy of IT controls with the resources that are
available, and we will remain dedicated to the goal of protecting our
Nation’s veterans. Our efforts will include protection of data
maintained by VBA as one of the major VA components.
Chairman Miller, Chairman Boozman, and Members of the Subcommittees,
thank you again for this opportunity to provide you the status of our
work. I am available to answer any questions.
