NIST 800-171 Control 3.3.9: Audit Management & Logging Access
Control 3.3.9 requires organizations to limit audit logging administration to a restricted set of privileged users to prevent unauthorized tampering and ensure audit trail integrity. This protects your organization's ability to detect and investigate security incidents across critical systems. Implementing proper audit management controls is essential for maintaining compliance and defending against insider threats.
What this means
Audit management controls restrict who can access, modify, or delete audit logs. Only qualified privileged users—such as security administrators and compliance officers—should have permissions to configure logging, review audit trails, or manage log retention. This separation of duties prevents malicious actors or unauthorized personnel from concealing their activities or corrupting evidence needed for investigations.
How to comply
- 1.Identify and document all privileged users authorized to manage audit logs and logging systems
- 2.Implement role-based access controls (RBAC) limiting audit log administration to named individuals
- 3.Configure systems to log all audit management activities, including configuration changes and log deletions
- 4.Regularly review and validate that only authorized personnel retain audit management privileges
- 5.Establish a process for granting, modifying, and revoking audit management access based on job role changes
Evidence auditors look for
- Access control matrix showing which roles can administer audit logs
- System screenshots displaying RBAC configurations restricting audit log access
- Audit logs documenting who accessed or modified logging configurations
- Personnel records linking authorized administrators to their audit management roles
- Change management records for audit access permission modifications
- System administration procedures defining audit management responsibilities
