Department of Homeland Security[]

The Department of Homeland Security (DHS) Office of Inspector General (OIG) was established by the Homeland Security Act of 2002,[1] by an amendment to the Inspector General Act of 1978.


The Inspector General Act created independent audit and investigative units, called the Office of Inspector General (OIG). The mission of the OIG, as spelled out in the Act, is to:

  • Conduct and supervise independent and objective audits and investigations relating to agency programs and operations.
  • Promote economy, effectiveness, and efficiency within the agency.
  • Prevent and detect fraud, waste, and abuse in agency programs and operations.
  • Review and make recommendations regarding existing and proposed legislation and regulations relating to agency programs and operations.
  • Keep the agency head and the Congress fully and currently informed of problems in agency programs and operations.

To ensure objectivity, the IG Act empowers the IG with:

  • Independence to determine what reviews to perform.
  • Access to all information necessary for the reviews.
  • Authority to publish findings and recommendations based on the reviews.
