AU.L2-3.3.8 Audit Protection: Securing Your Compliance Records

What this means

This control ensures that audit logs, audit trails, and the tools used to generate them are protected from tampering. Unauthorized users cannot view, change, or erase audit records. This protection applies both to the logs themselves and to audit management systems. The goal is maintaining the integrity and availability of evidence that demonstrates your security posture and incident response.

How to comply

1. 1.Implement access controls restricting audit log and tool access to authorized personnel only, using role-based access control (RBAC).
2. 2.Enable audit log immutability or write-once, read-many (WORM) storage to prevent modification or deletion after creation.
3. 3.Encrypt audit logs both in transit and at rest to protect confidentiality and detect tampering.
4. 4.Store audit logs on separate systems from production environments to isolate them from compromise.
5. 5.Configure audit tools to prevent unauthorized configuration changes, such as disabling logging or altering retention policies.
6. 6.Maintain regular backups of audit logs in a secure, segregated location separate from primary audit systems.
7. 7.Monitor and log all access attempts to audit information and audit tools, including successful and failed access.
8. 8.Establish a retention policy that complies with regulatory requirements and prevents premature deletion of audit records.

Evidence auditors look for

• Access control matrix showing role-based permissions for audit log systems
• Screenshots of RBAC configuration in your audit management platform
• Documentation of immutability settings in log storage systems
• Encryption certificates and encryption configuration documentation
• Network segmentation diagrams showing audit systems isolated from production
• Audit tool configuration settings showing change-protection controls
• Backup verification logs and restoration test results
• Access logs showing monitoring of who accessed audit systems and when
• Log retention policy documentation with regulatory justification
• Comparison of audit logs before and after protection measures to demonstrate integrity
