Government Accountability Office, Critical Infrastructure Protection: DHS Action Needed to Enhance Integration and Coordination of Vulnerability Assessment Efforts (GAO-14-507) (Sept. 15, 2014) (full-text).
This report examines the extent to which DHS is positioned to (1) integrate DHS vulnerability assessments to identify priorities, (2) identify duplication and gaps within its coverage, and (3) manage an integrated and coordinated government-wide assessment approach.
The Department of Homeland Security]] (DHS) used 10 different assessment tools and methods from FY2011 through FY2013 to assess critical infrastructure vulnerabilities. Four of the 10 assessments did not include cybersecurity. The differences in the assessment tools and methods mean DHS is not positioned to integrate its findings in identifying priorities.
