The Information Security Registered Assessors Program (IRAP), established by the Australian Signals Directorate (ASD), helps Australian government agencies and organisations safeguard their information and communications technology (ICT) systems against cyber threats.

ASD-endorsed assessors, trained in the Australian Government Information Security Manual (ISM) and IRAP procedures, conduct evaluations to ensure ICT systems comply with ISM security requirements.

IRAP assessment offers several advantages for organisations, particularly those handling sensitive information or working with Australian government agencies:

• Enhanced Security – Helps identify vulnerabilities and strengthen cybersecurity measures.

• Regulatory Compliance – Demonstrates alignment with the Australian Government’s Information Security Manual (ISM).

• Increased Credibility – Signals a commitment to high security standards, boosting trust with clients and stakeholders.

• Competitive Advantage – Essential for securing government contracts and partnerships.

• Improved Risk Management – Provides a structured approach to assessing and mitigating security risks.

The ACSC created the ISM to guide executive personnel, mainly CISOs and CIOs, through cybersecurity processes and information security developments. Organisations are only directly required to comply with the ISM if they work with the government or another organisation that requires compliance.

The ISM provides guidelines similar to the National Institute of Standards and Technology (NIST) in the United States.

The ISM provides guidelines for the following areas of security:

• Personnel roles and clearances

• Incident response

• Cyber Vendor Risk Management

• Documentation

• Physical security

• Personnel security

• System management

• Cryptography

• Communications infrastructure

The exact timeline for an organisation to gain IRAP assessment will depend on the size and complexity of an organisation and the current health of the organisation’s security posture. Overall, IRAP assessment can take a few months to over a few years. Organisations that already maintain excellent cyber hygiene will have an easier time achieving certification than those that need to install extensive corrections to patch weaknesses.

Before pursuing an IRAP assessment, organisations should take several preparatory steps to ensure a smooth assessment process:

• Understand ISM Requirements – Familiarise yourself with the Australian Government’s Information Security Manual (ISM) to align security practices with compliance standards.

• Conduct a Gap Analysis – Identify areas where your current security posture may fall short of ISM requirements and address vulnerabilities.

• Implement Security Controls – Strengthen cybersecurity measures, including access controls, encryption, and incident response protocols.

• Train Staff – Ensure employees understand security policies and compliance obligations to maintain a strong security culture.

• Engage an IRAP Assessor Early – Consulting with an ASD-endorsed assessor before the formal assessment can help clarify expectations and improve readiness.
