Australian Government Information Security Manual (ISM)
Introduction
The ISM has been developed by the Defence Signals Directorate under their role to provide policies and standards for Australian Government agencies to assist in the protection of official government information that is processed, stored or communicated by Australian Government systems.
Authority
Australian Government agencies are required by the Australian Government Protective Security Manual (PSM) to comply with the ISM for the protection of official government information when it is processed, stored or communicated by Australian Government systems. Although requirements will be more stringent when national security classified information or non-national security classified information and systems are involved, even non-security classified information and systems should have some degree of protection if a reliable or accurate service is to be maintained.
Versions
As of the September 2009 release the complete ISM has been authorised for release into the public domain and covers all security classifications of information and systems.
