Information Security Registered Assessors Program (IRAP) Exam Mock Test

Overview of the IRAP Assessor Examination

The Information Security Registered Assessors Program (IRAP) is an Australian Signals Directorate (ASD) initiative managed by the Australian Cyber Security Centre (ACSC). The program provides high-quality ICT security assessment services to government and industry. An IRAP Assessor evaluates the implementation, appropriateness, and effectiveness of an organisation's cyber security controls against Australian Government requirements, principally the Protective Security Policy Framework (PSPF) and the Information Security Manual (ISM).

Securing endorsement as an ASD-recognised IRAP Assessor requires demonstrating deep technical knowledge, practical assessment experience, valid Australian government security clearance (typically NV1 or NV2), and successful completion of the official IRAP Assessor Examination. This practice examination is tailored for Australian cybersecurity consultants, enterprise security architects, and auditors preparing to sit the certification assessment.

Detailed Syllabus and Assessment Domains

The IRAP examination tests candidate expertise across several core domains essential for assessing Commonwealth and defence-sector systems:

1. Australian Government Governance and the PSPF

Candidates must understand how security governance operates across Australian Commonwealth entities. Key topics include:

• Core requirements of the Protective Security Policy Framework (PSPF), with specific focus on InfoSec policies (Policy 8: Sensitive and classified information, Policy 9: Access to information, and Policy 10: Safeguarding data from cyber threats).
• Australian privacy principles, the Privacy Act 1988, and compliance with the Archives Act.
• Classification systems: OFFICIAL, OFFICIAL: Sensitive, PROTECTED, SECRET, and TOP SECRET caveats and handling instructions.

2. The Information Security Manual (ISM) Principles & Controls

The ISM represents the cybersecurity cornerstone of Australian government systems. Assessed areas include:

• ISM cybersecurity principles: Govern, Protect, Detect, and Respond.
• Detailed control guidelines for enterprise networks, endpoints, identity and access management (IAM), hardware security, and system administration.
• Tailoring security controls using a threat-informed risk approach rather than tick-box compliance.

3. ASD Essential Eight and Maturity Models

Assessors must evaluate implementation against ASD's baseline mitigation strategies:

• Mitigation strategies against targeted cyber intrusions (Application control, Patch applications, Configure Microsoft Office macro settings, User application hardening, Restrict administrative privileges, Patch operating systems, Multi-factor authentication, and Regular backups).
• Assessing Essential Eight Maturity Levels (Maturity Level 1 through Maturity Level 3) and measuring effectiveness against realistic attacker tradecraft.

4. IRAP Assessment Methodology

The operational framework governing how assessments are conducted:

• Stage 1 (Design Review): System architecture examination, Security Risk Assessment (SRA), System Security Plan (SSP), Incident Response Plans, and Statement of Applicability (SOA).
• Stage 2 (Effectiveness Assessment): Practical testing, interviews, configuration reviews, physical security checks, and control validation in operational environments.
• Clarifying the distinction between an assessor's findings and the Authorising Officer's (accreditation authority) final risk acceptance.

5. Cloud Security and Outsourced Systems

• ACSC Cloud Security Assessment and Authorisation guidance.
• Shared responsibility models across IaaS, PaaS, and SaaS environments.
• Assessment of hyperscale cloud providers and ASD certified cloud environments hosting Australian government data.

Examination Format and Testing Rules

• Session Duration: 90 minutes allocated for completing all questions.
• Item Formats: Multiple-choice, multiple-response, and scenario-based questions evaluating practical auditor decision-making.
• Reference Material: Depending on the specific invigilation conditions, candidates may refer to unmodified digital copies of the Australian Government ISM and PSPF guidance.
• Identification: Test takers must present valid Australian Government photo ID (such as an Australian Driver Licence or Australian Passport) prior to starting.
• Integrity Policy: External communication, collaboration, screen recording, or unauthorized software usage is strictly prohibited. Violations result in immediate disqualification and potential reporting to credentialing bodies.

Scoring System and Passing Benchmarks

The IRAP Examination tests both factual recall and applied scenario analysis. The standard benchmark to achieve endorsement is an overall passing score of 75% or higher. Questions are scored neutrally; there is no negative marking or penalty for incorrect answers. Performance feedback typically details domain-level competency across the ISM controls, PSPF alignment, and assessment methodology.

Expert Preparation Strategies for Australian Practitioners

1. Internalise the ISM Framework: Rather than attempting to memorise all individual controls, learn the rationale, control objectives, and search navigation of the current ISM release published by the ACSC.
2. Understand PSPF and ISM Intersection: Master how PSPF Policy 8 and Policy 10 assign governance obligations to agency heads and how the ISM supplies the technical controls to meet those obligations.
3. Practice Drafting Assessment Findings: Prepare for questions asking how to write non-compliance observations and risk statements that clearly separate technical vulnerabilities from business operational risks.
4. Work Through Essential Eight Case Studies: Be ready to identify whether a given enterprise configuration satisfies Maturity Level 2 or Maturity Level 3 criteria, particularly regarding privileged access and application execution control.
5. Take Realistic Timed Mock Exams: Use our online mock test engine to simulate testing conditions, gauge pacing, and identify areas requiring further review before sitting the actual assessment.
