IS18 — Information and Cyber Security Policy (IS18)

The IS18 is a mandatory policy for Queensland Government agencies aimed at ensuring a consistent, risk-based approach to information and cyber security. Agencies must implement an Information Security Management System (ISMS) aligned with ISO 27001, manage risks systematically, and meet defined minimum security requirements including compliance with the Essential Eight Strategies. The policy also requires annual security assurance attestations by accountable officers and incident reporting to the Queensland Government Cyber Security Unit. The scope covers all information systems, applications, technologies, and their associated risks, with guidance on operational technology and supply chain management. By adopting IS18, the government aims to align with international standards, reduce cybersecurity risks, and improve resilience.
