ISO 27001 - IT Asset Register Template
IT Asset Register as the Foundation of ISMS Risk Management
Required to support ISO/IEC 27001:2022 Clauses 5 & 6 - examined during every certification and surveillance audit.
The IT Asset Register is a core ISMS record under ISO/IEC 27001:2022. It enables organisations to identify information assets, assign ownership, and establish risk context aligned to business objectives.
Auditors review the asset register during Stage 1 and Stage 2 audits to verify ISMS scope, asset completeness, ownership accountability, and alignment with risk assessment and treatment. Incomplete or poorly maintained registers frequently result in audit findings, rework, or certification delays.
This template delivers a structured, defensible, auditor-ready IT Asset Register, designed to integrate seamlessly with your ISO 27001 risk management and control framework.

The IT Asset Register is one essential component of a complete ISO 27001 Information Security Management System (ISMS).
