The Australian Cyber Security Centre (ACSC) within the Australian Signals Directorate (ASD) produces the Australian Government Information Security Manual (ISM)


The ISM helps organisations use their risk management framework to protect information and systems from cyber threats. The cyber security guidelines within the ISM are based on the experience of the ACSC within ASD.

Intended audience

These guidelines are intended for Chief Information Security Officers (CISOs), Chief Information Officers (CIOs), cyber security professionals and information technology managers. As such, these guidelines discuss both governance and technical concepts in order to support the protection of organisations’ information and systems.
