ISO 27001:2022 Annex A 5.17 Checklist Guide

ISO 27001 A.5.17 Authentication Information Checklist

A.5.17 Authentication Information is a crucial control within the ISO 27001:2022 standard that emphasises the proper management and protection of authentication information used to verify the identity of users, systems, and processes.

This control ensures that authentication information, such as passwords, cryptographic keys, and tokens, is protected from unauthorised access and misuse, thereby maintaining the integrity and security of the information systems.

Purpose of Annex A.5.17

The main goal of A.5.17 is to secure authentication information, ensuring it is properly managed and protected to prevent unauthorised access, misuse, and potential data breaches. This involves implementing strong authentication mechanisms, ensuring secure storage and transmission, restricting access to authorised personnel, and maintaining a robust incident response plan.

Key Elements of A.5.17 Authentication Information

1. Authentication Policy: Establish and document a clear policy for managing authentication information, defining requirements for creating, storing, and handling authentication data.
2. Strong Authentication Mechanisms: Implement robust authentication mechanisms, including complex passwords, multi-factor authentication (MFA), and secure token management, to make bypassing authentication controls difficult.
3. Secure Storage: Ensure authentication information is stored securely using encryption or other appropriate methods to prevent unauthorised access.
4. Transmission Security: Protect authentication information during transmission across networks using secure communication protocols like HTTPS, TLS, and VPNs.
5. Access Control: Restrict access to authentication information to authorised personnel only, employing role-based access control (RBAC) to manage access rights.
6. Regular Updates and Review: Regularly update and review authentication information to ensure continued effectiveness, including periodic password changes, updating security keys, and reviewing access permissions.
7. Incident Response: Develop and implement procedures for responding to incidents involving compromised authentication information, including identifying breaches, notifying affected parties, and taking corrective actions.
