The Australian Signals Directorate’s Australian Cyber Security Centre (ACSC) has developed prioritised mitigation strategies to help cyber security professionals in all organisations mitigate cyber security incidents caused by various cyber threats. This guidance addresses targeted cyber intrusions (i.e. those executed by advanced persistent threats such as foreign intelligence services), ransomware and external adversaries with destructive intent, malicious insiders, business email compromise, and industrial control systems. 

This guidance is informed by the ACSC’s experience in responding to cyber security incidents, performing vulnerability assessments and penetration testing Australian government organisations.
