Reveal their secrets....Protect our own

Our mission tells a lot about what we do. DSD is the national agency responsible for collection, analysis and distribution of foreign signals intelligence (known as Sigint); and is the national authority on communications and computer security (Infosec).

As part of the Department of Defence, and sitting within the Australian Intelligence Community – DSD incorporates some of the most powerful leading edge technologies in a dynamic environment to support its objectives;

Combating International Crime, Weapons Proliferation and Terrorism

Supporting Military Operations

Protecting Australian Government Computer Networks

The work we perform is dynamic, unique, critical and incredibly rewarding.

DSD’s information security role is not classified and up to date information can be found by following the various links on the navigation bar at the top of this page.

While the Directorate’s intelligence – related activities and operations are classified in the interest of national security, we invite you to browse our website which contains general unclassified information about our organisation, its objectives and long standing history devoted to securing Australia and its interests.
