How to use this skill
Bring this guide into your coding agent with a prompt tailored to the tool you use.
- Open your project in Codex.
- Copy and paste the prompt below.
- Review files and risks before approving any action.
Inspect the Agent Skill at https://github.com/CyberStrikeus/CyberStrike/blob/HEAD/.cyberstrike/skill/NIST/SP800-53_rev5/AU_audit-and-accountability/AU-12(3)_changes-by-authorized-individuals/SKILL.md and all supporting files. Report provenance, permissions, scripts, dependencies, and security risks. Propose an exact installation into .agents/skills/au-12-3-changes-by-authorized-individuals, but wait for my approval before writing files or running scripts.

AU-12(3) Changes by Authorized Individuals
Enhancement of: AU-12
High-Level Description
Family: Audit and Accountability (AU) Framework: NIST SP 800-53 Rev 5
Permitting authorized individuals to make changes to system logging enables organizations to extend or limit logging as necessary to meet organizational requirements. Logging that is limited to conserve system resources may be extended (either temporarily or permanently) to address certain threat situations. In addition, logging may be limited to a specific set of event types to facilitate audit reduction, analysis, and reporting. Organizations can establish time thresholds in which logging actions are changed (e.g., near real-time, within minutes, or within hours).
What to Check
- Verify AU-12(3) Changes by Authorized Individuals is documented in SSP
- Confirm control is operating effectively
- Review evidence of continuous monitoring for AU-12(3)
- Verify enhancement builds upon base control AU-12
How to Test
Step 1: Review Documentation
Examine the System Security Plan (SSP) and related artifacts for AU-12(3) 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.
