AU-12(1)_system-wide-and-time-correlated-audit-trail
DevOps & SecurityAU-12(1)_system-wide-and-time-correlated-audit-trail 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.
Compile audit records from [organization-defined] into a system-wide (logical or physical) audit trail that is time-correlated to within [organization
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(1)_system-wide-and-time-correlated-audit-trail/SKILL.md and all supporting files. Report provenance, permissions, scripts, dependencies, and security risks. Propose an exact installation into .agents/skills/au-12-1-system-wide-and-time-correlated-audit-trail, but wait for my approval before writing files or running scripts.

AU-12(1) System-wide and Time-correlated Audit Trail
Enhancement of: AU-12
High-Level Description
Family: Audit and Accountability (AU) Framework: NIST SP 800-53 Rev 5
Audit trails are time-correlated if the time stamps in the individual audit records can be reliably related to the time stamps in other audit records to achieve a time ordering of the records within organizational tolerances.
What to Check
- Verify AU-12(1) System-wide and Time-correlated Audit Trail is documented in SSP
- Confirm control is operating effectively
- Review evidence of continuous monitoring for AU-12(1)
- 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(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.

Implementation Guidance
Audit trails are time-correlated if the time stamps in the individual audit records can be reliably related to the time stamps in other audit records to achieve a time ordering of the records within organizational tolerances.
