The Information Security Registered Assessors Program (iRAP) is an Australian Signals Directorate (ASD) initiative to provide high-quality information and communications technology (ICT) services to the government in support of Australia's security. iRAP provides the framework to endorse individuals from the private and public sectors to provide cyber security assessment services to Australian governments. Endorsed iRAP Assessors can provide an independent assessment of ICT security, suggest mitigations, and highlight residual risks. iRAP Assessors may provide assessment up to the TOP SECRET level for cloud services and others.

While no set of mitigation strategies are guaranteed to protect against all cyber threats, organisations are recommended to implement eight essential mitigation strategies from the ACSC’s Strategies to Mitigate Cyber Security Incidents as a baseline. This baseline, known as the Essential Eight, makes it much harder for adversaries to compromise systems.
