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-2(7)_privileged-user-accounts/SKILL.md and all supporting files. Report provenance, permissions, scripts, dependencies, and security risks. Propose an exact installation into .agents/skills/ac-2-7-privileged-user-accounts, but wait for my approval before writing files or running scripts.

AC-2(7) Privileged User Accounts
Enhancement of: AC-2
High-Level Description
Family: Access Control (AC) Framework: NIST SP 800-53 Rev 5
Privileged roles are organization-defined roles assigned to individuals that allow those individuals to perform certain security-relevant functions that ordinary users are not authorized to perform. Privileged roles include key management, account management, database administration, system and network administration, and web administration. A role-based access scheme organizes permitted system access and privileges into roles. In contrast, an attribute-based access scheme specifies allowed system access and privileges based on attributes.
What to Check
- Verify AC-2(7) Privileged User Accounts is documented in SSP
- Validate all 4 control requirements are implemented
- Confirm control is operating effectively
- Review evidence of continuous monitoring for AC-2(7)
- Verify enhancement builds upon base control AC-2
How to Test
Step 1: Review Documentation
Examine the System Security Plan (SSP) and related artifacts for AC-2(7) 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.

Remediation Guide
Control Statement
Establish and administer privileged user accounts in accordance with [organization-defined]; Monitor privileged role or attribute assignments; Monitor changes to roles or attributes; and Revoke access when privileged role or attribute assignments are no longer appropriate.
Implementation Guidance

Privileged roles include key management, account management, database administration, system and network administration, and web administration. A role-based access scheme organizes permitted system access and privileges into roles.
