Which office is responsible for overseeing the implementation of security policies regarding national security information?

The Information Security Oversight Office (ISOO) holds the primary responsibility for overseeing the implementation of security policies related to national security information. Established under the National Archives and Records Administration, the ISOO provides guidance, oversight, and recommendations for the protection of classified information across federal agencies. Its functions include monitoring compliance with security policies, conducting reviews, and ensuring effective handling of classified national security information.

In contrast, while the other offices may focus on various aspects of security related to intelligence or department-specific policies, they do not have the broad mandate or authority that is assigned to the ISOO for national security information. For example, the Security Programs Division is typically concerned with security within a specific organization, rather than overseeing national standards. The Intelligence Community Security Office deals with the security of the intelligence community specifically, and the Department of Defense Security Office primarily focuses on security matters within the Department of Defense. Thus, the ISOO is uniquely positioned to address national security information across all federal agencies comprehensively.
