Protection of Audit Information (03.03.08) Protection of Audit Information

High-Level Description

Family: Audit and Accountability Framework: NIST SP 800-171 Rev 3 Applicability: Systems processing, storing, or transmitting CUI

Protect audit information and audit logging tools from unauthorized access, modification, and deletion. Authorize access to management of audit logging functionality to only a subset of privileged users or roles.

What to Check

• Verify Protection of Audit Information (03.03.08) Protection of Audit Information is implemented for CUI systems
• Review SSP documentation for Protection of Audit Information (03.03.08)
• Validate CMMC Level 2 assessment objective for Protection of Audit Information (03.03.08)
• Confirm POA&M addresses any gaps for Protection of Audit Information (03.03.08)

How to Test

Step 1: Review System Security Plan

Examine the SSP for Protection of Audit Information (03.03.08) implementation description and responsible parties.

Step 2: Assess Implementation

# Verify security controls protecting CUI
# Check access controls, encryption, monitoring as applicable

# For Linux systems:
ls -la /etc/security/ 2>/dev/null
grep -r "CUI\|controlled" /etc/security/ 2>/dev/null

# For cloud:
# Use cloud-audit-mcp tools to assess posture

Step 3: CMMC Assessment Validation

Verify this requirement passes CMMC Level 2 assessment methodology per SP 800-171A Rev 3.

Requirement Statement

Protect audit information and audit logging tools from unauthorized access, modification, and deletion. Authorize access to management of audit logging functionality to only a subset of privileged users or roles.

Supplemental Guidance

Audit information includes the information needed to successfully audit system activity, such as audit records, audit log settings, audit reports, and personally identifiable information. Audit logging tools are programs and devices used to conduct audit and logging activities. The protection of audit information focuses on technical protection and limits the ability to access and execute audit logging tools to authorized individuals. The physical protection of audit information is addressed by media and physical protection requirements. Individuals or roles with privileged access to a system and who are also the subject of an audit by that system may affect the reliability of the audit information by inhibiting audit activities or modifying audit records. Requiring privileged access to be further defined between audit-related privileges and other privileges limits the number of users or roles with audit-related privileges.
