ISM (Information Security Manual)
How Scrutex Supports ISM Compliance
Executive Summary
The ISM is the Australian Government's primary information security guidance, mandatory for Commonwealth entities under the PSPF. It provides risk-based controls covering systems, networks, data, and communications across all classification levels. Scrutex supports ISM compliance across system security, vulnerability management, network monitoring, vendor oversight, and PSPF reporting obligations.
About ISM (Information Security Manual)
The ISM provides security control guidelines covering system security, communications, access control, media management, and personnel security. Controls are risk-based, selected according to information classification. Compliance is mandatory for Commonwealth agencies under the PSPF. Defence industry participants under DISP and many state governments also adopt the ISM.
Geographic and Sector Applicability
Mandatory for Australian Commonwealth agencies. Expected for DISP defence industry participants. Widely adopted by state governments and critical infrastructure operators aligning with government standards.
Who Should Care
Agency CISO
Owns ISM control implementation.
IT Security Adviser (ITSA)
Provides security advice on systems and accreditation.
Agency Head
Accountable under PSPF for protective security.
Key Risks of Non-Compliance
PSPF maturity assessment failures reported to the Attorney-General's Department.

Common Compliance Gaps
Incomplete External Asset Awareness
ISM system management guidelines require asset identification. Government agencies frequently have internet-facing systems not captured in formal registers.
Patching Compliance Gaps
The Essential Eight (ASD's priority mitigations) includes patching applications and operating systems. Many agencies struggle with timely patching of external-facing systems.
