The Information Security Manual (ISM) is the Australian Government’s authoritative cyber security framework. It defines the principles and guidelines that organisations should follow to govern, protect, detect, respond to, and recover from cyber threats. The ISM covers technology, people, processes, and suppliers, recognising that cyber security failures rarely stem from a single technical weakness alone.
The core purpose of the Information Security Manual is to provide risk-based, defensible guidance for managing cyber security across systems, applications, suppliers, and data throughout their lifecycle. The ISM does not aim to eliminate risk entirely. Instead, it focuses on helping organisations understand cyber threats, implement proportionate controls, and make informed decisions about residual risk.
The primary audience includes executives, directors, risk owners, cyber security leaders, and technology teams. Importantly, the ISM is designed to support accountability at the leadership level. It requires clear ownership of cyber risk, documented risk acceptance, and ongoing assurance that controls remain effective as threats and technologies evolve.
For executives and boards, the ISM provides a common language for discussing cyber security in terms of risk, impact, and governance, rather than tools or technical detail. This makes it easier to integrate cyber security into broader enterprise risk management and strategic planning.
Why ISM/ Benefits
- Governance and risk: Clear accountability, defined risk appetite, documented risk acceptance, and regular reporting to leadership. This ensures cyber security decisions are visible, deliberate, and defensible.
- Identity and access: Strong authentication, privileged access management, and least-privilege principles. Identity remains one of the most common paths used by threat actors, making this a critical control area.
- System hardening and patching: Secure configurations, timely patching, and application controls reduce exposure to known vulnerabilities that are frequently exploited.
- Monitoring and detection: Centralised logging, alerting, and analysis enable early detection of cyber threats and faster response when incidents occur.
- Incident response and recovery: Documented and tested response plans, reliable backups, and clearly defined recovery objectives support operational resilience and minimise downtime.
- Supplier assurance
- Managed services, cloud providers, and third parties are assessed and monitored to ensure they meet ISM expectations, reducing supply chain risk.
- Together, these components help organisations move from reactive security to predictable, repeatable cyber risk management.
