ASD Codenames/Covernames and Suggested Use/Implementation

This page contains a listing of covernames associated with the Australian Signals Directorate (ASD), which was previous named the Defense Signals Directorate (DSD). ASD is responsible for providing signals intelligence (SIGINT) and information assurance services to the government and assistance to other Australian government agencies.

I have produced similar lists for Communications Security Establishment (CSE)Government Communications Headquarters (GCHQ), Government Communications Security Bureau (GCSB), and National Security Agency (NSA). You may also want to visit, which has also developed lists of covernames for some of the above mentioned agencies.

In some cases, you may find that covernames are listed across different agencies. This results from how covernames lists have often been created, which involved close reading of documents that were associated with different agencies and then listing covernames under the agency which authored the documents. In all cases, I would suggest you search across agency covername lists when researching a given covername.

All material provided below is derived from publicly available documents, books, and other resources. Descriptions of what the covernames mean or refer to are done on a best-effort basis; if you believe there is additional publicly referenced material derived from ASD documents which could supplement descriptions please let me know.

As of writing, no reviewed Snowden document explicitly discloses an ASD cover name.
