  • •CI Fortify initiative launched to enhance resilience in critical infrastructure.
  • •Operators must prepare for attacks by isolating operational technology systems.
  • •Recent attacks on U.S. water systems underscore the urgency of these measures.

The CI Fortify initiative, launched by CISA and the Australian Cyber Security Centre, emphasizes the need for critical infrastructure operators to prepare for cyber attacks by isolating operational technology (OT) systems. This shift comes after state-linked cyber threats, including recent attacks on U.S. water systems attributed to Iranian hackers, highlighted vulnerabilities in essential services. The guidance outlines steps for mapping critical assets, building separation points, and developing isolation plans to maintain operations during cyber incidents. The initiative aims to enhance resilience against attacks that may already have access to systems. While many vulnerabilities remain familiar, the focus is now on containment and recovery rather than solely prevention. The initiative's recommendations are critical for safeguarding essential services against increasingly sophisticated threats.
