-  At a Glance
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.
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.

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
	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.
