AC-12(1)_user-initiated-logouts
DevOps & SecurityAC-12(1)_user-initiated-logouts 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.
Provide a logout capability for user-initiated communications sessions whenever authentication is used to gain access to [organization-defined].
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-12(1)_user-initiated-logouts/SKILL.md and all supporting files. Report provenance, permissions, scripts, dependencies, and security risks. Propose an exact installation into .agents/skills/ac-12-1-user-initiated-logouts, but wait for my approval before writing files or running scripts.
Copying this prompt does not install or run the skill. Review third-party files before use.
AC-12(1) User-initiated Logouts
Enhancement of: AC-12
High-Level Description
Family: Access Control (AC) Framework: NIST SP 800-53 Rev 5
Information resources to which users gain access via authentication include local workstations, databases, and password-protected websites or web-based services.
What to Check
- Verify AC-12(1) User-initiated Logouts is documented in SSP
- Confirm control is operating effectively
- Review evidence of continuous monitoring for AC-12(1)
- Verify enhancement builds upon base control AC-12
How to Test
Step 1: Review Documentation
Examine the System Security Plan (SSP) and related artifacts for AC-12(1) 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.
