We evaluated the Department of Homeland Security’s (DHS) enterprise-wide security program for Top Secret/Sensitive Compartmented Information intelligence systems. Pursuant to the Federal Information Security anagement Act, we reviewed the Department’s security program including its policies, procedures, and system security controls for enterprise-wide intelligence systems. In doing so, we assessed the Department’s continuous monitoring, configuration management, identity and access management, incident response and reporting, risk management, security training, plans of actions and milestones, remote access, contingency planning, contractor systems and security capital planning. The United States Coast Guard (USCG) has migrated the Coast Guard Intelligence Support System into a new system that is supported by DHS, the Defense ntelligence Agency and USCG.
