Why We Did This Review
We sought to assess the
security configurations of the
U.S. Environmental Protection
Agency's (EPA's) Region 1
wireless network infrastructure.
We also sought to conduct
network vulnerability testing of
the Region 1 Local Area
Network to identify resources
that contained commonly
known high-risk and medium-
risk vulnerabilities.
Background
We conducted this audit as part
of the annual review of EPA's
information security program
as required by the Federal
Information Security
Management Act. We
conducted network
vulnerability testing in
February 2012 to identify any
commonly known network
vulnerabilities and to present
the results to the appropriate
EPA officials, who can then
promptly remediate or
document planned actions to
resolve the weaknesses.
For further information, contact
our Office of Congressional and
Public Affairs at (202) 566-2391.

Results of Technical Network Vulnerability
Assessment: EPA's Region 1
What We Found
Our vulnerability assessments of Region l's wireless network infrastructure
found no security weaknesses. However, our vulnerability testing of networked
resources located at the Region 1 facility identified Internet Protocol addresses
with potentially 18 high-risk and 166 medium-risk vulnerabilities. Regional and
headquarter offices manage resources located in Region 1 that contain these
weaknesses. The Office of Inspector General (OIG) met with EPA information
security personnel from the respective offices to discuss the findings. EPA
information security personnel acknowledged the existence of the identified
security weaknesses and began immediate remediation of some of these issues.
If not resolved, these vulnerabilities could expose EPA's assets to unauthorized
access and potentially harm the Agency's network.
What We Recommend
We recommend that the Senior Information Officials within Region 1 and the
Office of Environmental Information:
	Provide the OIG a status update for all identified high-risk and medium-
risk vulnerability findings within 30 days of this report.
	Create plans of action and milestones in the Agency's Automated
Security Self-Evaluation and Remediation Tracking system for all
vulnerabilities according to Agency procedures within 30 days of this
report.
	Perform a technical vulnerability assessment test of assigned network
resources within 60 days to confirm completion of remediation activities.
The detailed testing results have already been provided to Agency
representatives. Due to the sensitive nature of the report's technical findings, the
technical details will not be made available to the public.
Planned Agency Corrective Actions
Region 1 remediated all high-risk vulnerabilities discovered by our vulnerability
testing of networked resources. Additionally, Region 1 acknowledged the
existence of the additional vulnerabilities that we identified and began mitigation
activities related to these risks.

MEMORANDUM
SUBJECT: Results of Technical Network Vulnerability Assessment:
EPA's Region 1
Report No. 12-P-0518
FROM: Arthur A. Elkins, Jr.

TO:
Fred Weeks
Acting Senior Information Official
Region 1
Renee Wynn
Principal Deputy Assistant Administrator and Senior Information Official
Office of Environmental Information
This is our final report on the above subject audit conducted by the Office of Inspector General
(OIG) of the U.S. Environmental Protection Agency (EPA). The site assessment was conducted
in conjunction with our annual audit of EPA's information security program as required by the
Federal Information Security Management Act. This report provides the summary of our security
testing of networked resources located at EPA's Region 1 office. Our test disclosed that network
resources at the Region 1 office contained potentially 18 high-risk and 166 medium-risk
vulnerabilities. Upon analysis of the testing results, we found that both regional and headquarters
offices are responsible for managing the resources located in Region 1 that contain these
weaknesses. We provided your office representatives with the technical results during our site
visit in order to facilitate immediate remediation actions. All 18 high-risk vulnerabilities were
remediated before the issuance of this report.
We performed this audit work from February through May 2012 at EPA's Region 1 offices in
Boston, Massachusetts. We performed this audit in accordance with generally accepted
government auditing standards. These standards require that we plan and perform the audit to
obtain sufficient and appropriate evidence to provide a reasonable basis for our findings and
conclusions based on the audit objectives. We believe the evidence obtained provides a
reasonable basis for our findings and conclusions.

-------
We conducted testing to identify the existence of commonly known vulnerabilities using a
commercially available network vulnerability assessment tool recognized by the National
Institute of Standards and Technology. We interviewed EPA personnel responsible for managing
the network resources located in Region 1. We reviewed relevant EPA policies to obtain an
understanding of the Agency's Automated Security Self-Evaluation and Remediation Tracking
(ASSERT) system used for recording identified weaknesses. We tested the Internet Protocol
addresses associated with network resources located in the Region 1 office. We used the risk
ratings provided by the vulnerability software to determine the level of harm a vulnerability
could cause to a networked resource and accepted the results from the software tool as the level
of risk to EPA's network. Upon follow-up with your office representatives, they acknowledged
the existence of the vulnerabilities and stated that some mitigation activities had already begun
related to these risks.
We also conducted testing of Region 1 's wireless infrastructure to identify any possible
configuration weaknesses using a commercially available wireless scanning tool. Specifically,
we tested to identify whether any unauthorized wireless devices existed on the region's network.
We also tested to determine whether the wireless encryption protocols being used on the region's
wireless local area network were sufficient to secure it. We found no weaknesses during either of
these tests.
Recommendations
We recommend that the Senior Information Officials within Region 1 and the Office of
Environmental Information:
1.	Provide the OIG a status update for all identified high-risk and medium-risk
vulnerability findings.
2.	Create plans of action and milestones in the Agency's Automated Security Self-
Evaluation and Remediation Tracking system for all vulnerabilities according to
Agency procedures.
3.	Perform a technical vulnerability assessment test of assigned network resources
within 60 days to confirm completion of remediation activities.
Action Required
Please provide written responses to this report within 30 calendar days. You should include a
corrective actions plan for agreed-upon actions, including milestone dates.
Due to the sensitive nature of the report's technical findings, the technical details are not
included in this report and will not be made available to the public. The OIG plans to post on the
OIG's public website the corrective action plans that you provide to us that do not contain
sensitive information. Therefore, we request that you provide the response to recommendation 1
in a separate document, and we will not make that response available to the public if it contains
sensitive information.

response to recommendation 1, which will not be posted if it contains sensitive information, your
responses should not contain data that you do not want to be released to the public; if those
responses contain such data, you should identify the data for redaction or removal.
If you or your staff have any questions regarding this report, please contact Patricia H. Hill,
