DevOps & SecurityAC-6(9)_log-use-of-privileged-functions is an Agent Skill for devops & security published in the CyberStrikeus/CyberStrike repository on GitHub: a SKILL.md instruction file an AI agent can load to do this task.
Log the execution of privileged functions.
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/AC_access-control/AC-6(9)_log-use-of-privileged-functions/SKILL.md and all supporting files. Report provenance, permissions, scripts, dependencies, and security risks. Propose an exact installation into .agents/skills/ac-6-9-log-use-of-privileged-functions, but wait for my approval before writing files or running scripts.

AC-6(9) Log Use of Privileged Functions
Enhancement of: AC-6
High-Level Description
Family: Access Control (AC) Framework: NIST SP 800-53 Rev 5
The misuse of privileged functions, either intentionally or unintentionally by authorized users or by unauthorized external entities that have compromised system accounts, is a serious and ongoing concern and can have significant adverse impacts on organizations. Logging and analyzing the use of privileged functions is one way to detect such misuse and, in doing so, help mitigate the risk from insider threats and the advanced persistent threat.
What to Check
- Verify AC-6(9) Log Use of Privileged Functions is documented in SSP
- Confirm control is operating effectively
- Review evidence of continuous monitoring for AC-6(9)
- Verify enhancement builds upon base control AC-6
How to Test
Step 1: Review Documentation
Examine the System Security Plan (SSP) and related artifacts for AC-6(9) 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.
