From the Introduction: "Our Independent Review of the Washington Navy Yard Shooting has identified structural gaps and weaknesses in Department of Defense (DoD) security programs, policies and procedures. Fixing these flaws is essential to prevent future tragedies, and to ensure that those who died on September 16, 2013 did not perish in vain. The changes we recommend are fundamental and far-reaching, and reflect the need to replace the underlying premise of installation and personnel security. For decades, DoD has framed installation security as a perimeter problem: Defend the perimeter, and installations can keep threats at bay. This paradigm is outdated. Threats to our personnel and classified information increasingly lie within our installations, and come from DoD employees and contractors who are trusted insiders. The Department of Defense needs to strengthen security from within, and reframe its policies and programs to counter insider threats. The current official definition of insider threats focuses on those who use their 'authorized access, wittingly or unwittingly, to do harm to the security of the United States.' The definition goes on to include 'espionage, terrorism, or unauthorized disclosure' as examples. Although acts of workplace violence are not specifically mentioned, we found that many security gaps and weaknesses are common to all such insider challenges. Our report seeks to improve security against the full range of threats within DoD facilities, from severely troubled employees to those who knowingly serve America's adversaries."
