The ACSC Essential Eight is a cybersecurity mitigation framework developed by the Australian Cyber Security Centre (ACSC) to help organisations protect against common and high-impact cyber threats. It outlines eight practical security controls designed to reduce the risk of ransomware, data breaches, and unauthorised system access. The ACSC Essential Eight includes application control, patch management, multi-factor authentication, restriction of administrative privileges, and regular data backups, among other strategies. Widely adopted across Australian Government agencies and increasingly implemented by private sector organisations, the framework provides a structured and prioritised approach to improving cyber resilience. By aligning security programs with the ACSC Essential Eight, organisations can demonstrate proactive risk management, strengthen compliance posture, and significantly reduce their exposure to evolving cyber threats in the Australian threat landscape.
