The Australian Signals Directorate (ASD, formerly DSD) is an intelligence agency in the Australian Government Department of Defence, with its headquarters in Canberra.

Our mission, ‘Reveal their secrets, protect our own’, accurately summarises our role. ASD:

• collects and analyses foreign signals intelligence, known as Sigint
• provides advice and assistance on information and communications security, known as InfoSec.

This authority is not obliged to respond to your request under FOI, but we feel it should be.
