Compliance Framework Alignment Skill

Purpose

This skill provides a unified cross-framework compliance alignment for the CIA platform, mapping controls between ISO 27001:2022, NIST CSF 2.0, CIS Controls v8, and GDPR. It enables developers and security teams to understand how a single implementation satisfies multiple compliance requirements simultaneously.

When to Use This Skill

Apply this skill when:

✅ Implementing security controls that must satisfy multiple frameworks
✅ Preparing for compliance audits
✅ Documenting control implementations
✅ Assessing compliance gaps
✅ Justifying security investments to stakeholders
✅ Reviewing architecture changes for compliance impact
✅ Updating ISMS documentation

Do NOT use for:

❌ Detailed control implementation (use framework-specific skills)
❌ Risk assessment methodology (use risk-assessment-methodology)
❌ Incident response procedures (use incident-response)

Decision Framework

Implementing a New Security Control
    │
    ├─→ Identify all applicable framework requirements
    │   └─→ Check ISO 27001, NIST CSF, CIS, GDPR mappings above
    │
    ├─→ Design control to satisfy ALL applicable frameworks
    │   └─→ One implementation, multiple compliance benefits
    │
    ├─→ Document control implementation
    │   └─→ Map to specific control IDs in each framework
    │
    ├─→ Collect evidence of implementation
    │   └─→ Automated where possible (CI/CD, logs, configs)
    │
    └─→ Verify control effectiveness
        └─→ Test, review, and audit periodically
