The Homeland Security Information Network (HSIN) is maintained by the Department of Homeland Security (DHS), Office of Operations, Coordination and Planning (OPS) on the Sensitive but Unclassified (SBU) network. HSIN is designed to facilitate the secure integration and interoperability of information-sharing resources between federal, state, local, tribal, territorial, private sector, international, and other non-governmental partners involved in identifying and preventing terrorism as well as in undertaking incident management activities. HSIN is a user-driven, web-based, information-sharing platform that connects all homeland security mission partners within a wide spectrum of homeland security mission areas. HSIN contains personally identifiable information (PII) about the homeland security enterprise, HSIN users, and members of the public who are the subject of documents, reports, or bulletins contained in the HSIN collaboration spaces. This Privacy Impact Assessment (PIA) only covers the substantive material posted and shared within the HSIN collaboration spaces, and not the individual user accounts. Federal records contained within HSIN are governed by the source system of records notice (SORN) and Freedom of Information Act (FOIA). Non-federal records contained in HSIN are governed by the laws and regulations applicable to the relevant foreign, state, or local agencies who participate in HSIN.
