AU-12(4)_query-parameter-audits-of-personally-identifiable-informatio
DevOps & SecurityAU-12(4)_query-parameter-audits-of-personally-identifiable-informatio 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 and implement the capability for auditing the parameters of user query events for data sets containing personally identifiable information.
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(4)_query-parameter-audits-of-personally-identifiable-informatio/SKILL.md and all supporting files. Report provenance, permissions, scripts, dependencies, and security risks. Propose an exact installation into .agents/skills/au-12-4-query-parameter-audits-of-personally-identifiable-informatio, but wait for my approval before writing files or running scripts.

AU-12(4) Query Parameter Audits of Personally Identifiable Information
Enhancement of: AU-12
High-Level Description
Family: Audit and Accountability (AU) Framework: NIST SP 800-53 Rev 5
Query parameters are explicit criteria that an individual or automated system submits to a system to retrieve data. Auditing of query parameters for datasets that contain personally identifiable information augments the capability of an organization to track and understand the access, usage, or sharing of personally identifiable information by authorized personnel.
What to Check
- Verify AU-12(4) Query Parameter Audits of Personally Identifiable Information is documented in SSP
- Confirm control is operating effectively
- Review evidence of continuous monitoring for AU-12(4)
- 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(4) 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.
