DoD Installations: Monitoring Use of Physical Access Control Systems Could Reduce Risks to Personnel and Assets

In November 2009, an Army officer killed or wounded 45 people at Fort Hood, Texas; 4 years later in September 2013, a Navy contractor killed or wounded 16 people at the Washington Navy Yard in Washington, D.C. Independent reviews conducted in the aftermath of these shootings identified physical access control weaknesses at DOD installations. The conference report accompanying the National Defense Authorization Act for Fiscal Year 2018 contained a provision for GAO to assess DOD's installation access control efforts. GAO (1) described actions DOD has taken to develop guidance on physical access to domestic installations and to field PACS at these installations, (2) evaluated the extent to which DOD has monitored the use of fielded PACS at these installations, and (3) evaluated the extent to which DOD has implemented an approach for addressing PACS technical issues and assessing associated performance. GAO analyzed DOD guidance on physical access control requirements, and visited installations to discuss with installation command and security force officials their experiences using PACS. This is a public version of a sensitive report that GAO issued in May 2019. Information that DOD deemed sensitive has been omitted.
