Australia’s Cyber Incident Management Arrangements (CIMA) outlines the inter-jurisdictional coordination arrangements and principles for Australian governments’ cooperation in response to national cyber incidents.
The CIMA bridges the current gap between a localised cyber security incident handled by an individual state, and Australia’s national crisis management arrangements. If a national cyber incident reaches a crisis level, the CIMA will operate in support of jurisdictions’ respective crisis management arrangements.
The CIMA categorises cyber incidents under National Cyber Security Arrangements (NCSA) from Level 5 to Level 1:
Level 5: Normal Conditions
Level 4: Lean Forward
Level 3: Alert
Level 2: National Cyber Incident
Level 1: National Cyber Crisis
