Homeland Security: Progress Has Been Made to Address the Vulnerabilities Exposed by 9/11, but Continued Federal Action Is Needed to Further Mitigate Security Risks, Full-text GAO-07-375, and Highlights, January 24, 2007.
“While much attention has been focused on mitigating the specific risks of 9/11, other critical assets ranging from passenger rail stations to power plants are also at risk of terrorist attack. Deciding how to address these risks–setting priorities, making trade-offs, allocating resources, and assessing social and economic costs–is essential. Thus, it remains vitally important for DHS to continue to develop and implement a risk-based framework to help target where and how the nation’s resources should be invested to strengthen security.”
