GAO said Tuesday TSA developed a comprehensive risk assessment of perimeter and access control security in May 2013 after the agency assessed potential threats, vulnerabilities and consequence components of airport and access control risks.
The government watchdog added that TSA failed to update the assessment method with new information based on the current airport security risk environment involving insider threat.
âUpdating the risk assessment of airport security with information that reflects this current threat, among other things, would better ensure that TSA bases its risk management decisions on current information and focuses its limited resources on the highest-priority risks to airport security,â GAO said.
TSA also lacked a comprehensive assessment of the vulnerability related to TSA-regulated airports system due to budget constraints, according to GAO.
GAO also recommends TSA perform a system-wide assessment of airport vulnerability and update its strategy for airport perimeter and access control security.
