Audit Record Content (03.03.02) Audit Record Content

High-Level Description

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

Include the following content in audit records: What type of event occurred When the event occurred Where the event occurred Source of the event Outcome of the event Identity of the individuals, subjects, objects, or entities associated with the event Provide additional information for audit records as needed.

What to Check

• Verify Audit Record Content (03.03.02) Audit Record Content is implemented for CUI systems
• Review SSP documentation for Audit Record Content (03.03.02)
• Validate CMMC Level 2 assessment objective for Audit Record Content (03.03.02)
• Confirm POA&M addresses any gaps for Audit Record Content (03.03.02)

How to Test

Step 1: Review System Security Plan

Examine the SSP for Audit Record Content (03.03.02) 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

Include the following content in audit records: What type of event occurred When the event occurred Where the event occurred Source of the event Outcome of the event Identity of the individuals, subjects, objects, or entities associated with the event Provide additional information for audit records as needed.

Supplemental Guidance

Audit record content that may be necessary to support the auditing function includes time stamps, source and destination addresses, user or process identifiers, event descriptions, file names, and the access control or flow control rules that are invoked. Event outcomes can include indicators of event success or failure and event-specific results (e.g., the security state of the system after the event occurred). Detailed information that organizations consider in audit records may include a full text recording of privileged commands or the individual identities of group account users.
