DHS/ALL/PIA-052 DHS Insider Threat Program

The Department of Homeland Security (DHS) Insider Threat Program (ITP) was established as a department-wide effort to manage insider threat matters within DHS. The Insider Threat Program was mandated by E.O. 13587, ‘‘Structural Reforms to Improve the Security of Classified Networks and the Responsible Sharing and Safeguarding of Classified Information,’’ issued October 7, 2011, which requires all federal agencies that operate or access classified computer networks, to establish an insider threat detection and prevention program covering all users of classified computer networks (including contractors and others who operate or access classified computer networks controlled by the Federal Government), to ensure the security of classified networks and the responsible sharing and safeguarding of classified information on those networks with appropriate protections for privacy and civil liberties.

Insider threats include: attempted or actual espionage, subversion, sabotage, terrorism, or extremist activities directed against the Department and its personnel, facilities, resources, and activities; unauthorized use of or intrusion into automated information systems; unauthorized disclosure of classified, controlled unclassified, sensitive, or proprietary information or technology; and indicators of potential insider threats.

The DHS ITP monitors activity on all three DHS networks: Unclassified (A-LAN), SECRET (B-LAN also known as the Homeland Secure Data Network), and TOP SECRET (C-LAN also known as the Joint Worldwide Intelligence Communications System) for attempted or actual espionage, subversion, sabotage, terrorism, or extremist activities directed against the Department and its personnel, facilities, resources, and activities; unauthorized use of or intrusion into automated information systems; unauthorized disclosure of classified, controlled unclassified, sensitive or proprietary information or technology; and indicators of potential insider threats by covered persons.

DHS is updating this Privacy Impact Assessment (PIA) to reflect the application of the insider threat program to all networks. March 2018
