IACS Unified Requirements E26/E27 - Cyber Resilience of Ships and On-Board Systems

International (IACS — 12 classification societies)
v2024 (mandatory for new builds)
19 domains
19 controls

International Association of Classification Societies (IACS) Unified Requirements E26 (Cyber Resilience of Ships) and E27 (Cyber Resilience of On-Board Systems and Equipment), mandatory from 1 July 2024 for new ship construction contracts. E26 addresses ship-level cyber resilience requirements across the vessel lifecycle. E27 addresses equipment-level cyber security requirements for system integrators and equipment suppliers. Together they establish the first mandatory classification society cyber requirements for new builds. All 12 IACS member classification societies must implement these requirements (covering 90%+ of global tonnage). Aligned with IEC 62443 for industrial automation security.
