The US Department of Homeland Security is developing a new system that will centralise data on potential insider threats.A 26 February public notice published on, noted that the system will allow the Department of Homeland Security to manage insider threat inquiries, investigations, and other activities associated with complaints, inquiries, and investigations regarding the unauthorized disclosure of classified national security information.Interestingly, the the Department of Homeland Security will also be issuing a “Notice of Proposed Rulemaking” to exempt this system of records from certain provisions of the Privacy Act elsewhere in this Federal Register.The plan notes that threats include attempted or actual espionage, subversion, sabotage, terrorism, or extremist activities directed against DHS and its personnel, facilities, resources, and activities; unauthorized use of or intrusion into automated information systems.Biometric data is part of the information that should be protected from insider threats.
