CISA/Australia guidance on isolating OT systems during cyberattacks

  • Engineer — Plan: Review the guidance and map your OT/IT network segmentation against CISA’s isolation playbook; identify which systems have manual fallback modes and document runbooks for emergency isolation this quarter.
  • SOC/IR — Plan: Use this guidance to pressure-test your IR playbooks for OT environments — specifically, ensure you have documented procedures for triggering OT isolation and know who owns that call.
  • Leader — Learn: Joint US/Australian guidance signals regulatory direction for critical infrastructure operators; useful context for board-level resilience discussions but no immediate action required absent a specific deadline or incident.
