Number: 2007-20-117 to the Internal
Revenue Service Chief Information Officer.
IMPACT ON TAXPAYERS
The Internal
Revenue Service (IRS) processes and maintains personally identifiable
information for more than 130 million taxpayers who file their income tax
returns with the IRS. While the IRS has
accomplished several noteworthy actions to protect this information, managers
and employees have not complied with established security procedures. As a result, personally identifiable
information is being unnecessarily exposed to unauthorized access and potential
identity theft.
WHY TIGTA DID THE AUDIT
This audit
was initiated as part of a statute that requires each agency’s Inspector
General to review the policies and procedures related to personally identifiable
information and conduct reviews at least every 2 years to ensure it is
adequately protected. The overall
objective of this review was to determine the progress the IRS has made in
ensuring the security and privacy of personally identifiable information it
maintains.
WHAT
TIGTA FOUND
The IRS has taken several noteworthy actions to protect
taxpayer data in its possession. For
example, it has established a Security Services and Privacy Executive Steering
Committee to serve as the primary governance body for all matters relating to
security and privacy issues in the IRS.
In addition, it has made steady progress each year in complying with the
requirements of the Federal Information Security Management Act.
However, TIGTA reviews during Fiscal Years 2003 to 2007 have
identified persistent computer security weaknesses that jeopardize the security
of personally identifiable information. TIGTA
continues to find that employees are not aware of the security risks inherent
in their positions. For example, TIGTA reviews
found that employees did not sufficiently safeguard laptop computers and did
not encrypt data on the computers; were susceptible to social engineering
techniques that hackers could use to gain access to their systems; and ignored
IRS policies on the use of email, which increased security vulnerabilities.
Even employees with key security responsibilities continue
to ignore standard security configurations, often for their own convenience. One TIGTA review found that managers provided
employees access to systems and data the employees did not need and were not
aware of the access capabilities of their employees. Other TIGTA reviews found that technical
controls in modernized systems and the security infrastructure were
inadequate. Although industry guidance
recommends that security controls be designed into new systems early in the
development process, security has not been at the forefront when new systems are
developed in the IRS. Waiting until
systems are implemented to address security controls will most likely cost
significantly more than if security controls were considered during the
development of the systems.
It is clear that some IRS executives are not holding
managers and employees accountable for carrying out their responsibilities and
for ensuring managers and employees are aware of the security risks associated
with their positions. For the IRS to
make greater strides in improving computer security and protecting personally
identifiable information, managers and employees must be aware of the security
risks inherent to their positions and consider security implications in their
day-to-day activities. Executives must
clearly communicate expectations that procedures will be followed and take
appropriate actions when procedures are not followed.
WHAT TIGTA RECOMMENDED
Because TIGTA had already made recommendations related to
the aforementioned issues in prior audit reports, no additional recommendations
were made. TIGTA will continue to
monitor the IRS’ overall strategy and ability to protect and secure personally
identifiable information in future security-related reviews.
In
their response to the report, IRS officials agreed that, while progress is
being made, more needs to be done to
ensure the privacy and security over personally identifiable information is a
fundamental and top priority. The IRS plans
to continue to update its systems, processes, and training so employees are
aware of the steps they must take to prevent taxpayer information from being
compromised.
