AU-6(8) Full Text Analysis of Privileged Commands

Enhancement of: AU-6

High-Level Description

Family: Audit and Accountability (AU) Framework: NIST SP 800-53 Rev 5

Full text analysis of privileged commands requires a distinct environment for the analysis of audit record information related to privileged users without compromising such information on the system where the users have elevated privileges, including the capability to execute privileged commands. Full text analysis refers to analysis that considers the full text of privileged commands (i.e., commands and parameters) as opposed to analysis that considers only the name of the command. Full text analysis includes the use of pattern matching and heuristics.

What to Check

Verify AU-6(8) Full Text Analysis of Privileged Commands is documented in SSP
Confirm control is operating effectively
Review evidence of continuous monitoring for AU-6(8)
Verify enhancement builds upon base control AU-6

How to Test

Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for AU-6(8) implementation details. Verify the organization has documented how this control is satisfied.

Step 2: Validate Implementation

# For cloud environments, use cloud-audit-mcp tools
# For on-premises, review system configurations directly

# Example: Check if account management policies exist
grep -r "account.management\|access.control" /etc/security/ 2>/dev/null

Step 3: Test Operating Effectiveness

Verify the control is actively functioning, not just documented. Check logs, configurations, and operational evidence.

Tools

Tool	Purpose	Usage
cloud-audit-mcp	Check logging configuration	`cloud_audit_logging`
AWS CLI	Review CloudTrail/CloudWatch	`aws cloudtrail describe-trails`
