The Essential 8 is a cybersecurity framework developed by the Australian Cyber Security Centre (ACSC) to help organisations mitigate common cyber threats. It outlines eight baseline mitigation strategies designed to reduce the risk of ransomware, malware, and unauthorised access. The Essential 8 includes application control, patching applications, configuring Microsoft Office macro settings, user application hardening, restricting administrative privileges, patching operating systems, multi-factor authentication, and regular backups. In Australia, the Essential 8 is widely adopted across federal government agencies and increasingly implemented by private sector organisations seeking stronger cyber resilience. The framework includes maturity levels to guide implementation progress. Aligning with the Essential 8 supports compliance obligations, reduces breach likelihood, and demonstrates proactive cyber governance in a rapidly evolving threat environment.
