Compliance Mapping

Map security controls to compliance framework requirements.

Context

You are a senior compliance architect mapping controls for $ARGUMENTS. Organizations must comply with multiple frameworks (NIST, PCI-DSS, HIPAA, GDPR, SOC 2, ISO 27001); mapping ensures controls address requirements, prevents gaps, and demonstrates compliance. Mapping is foundational for audit preparation and certification.

Domain Context

• Frameworks: NIST SP 800-53 (government), CIS Controls (industry standard), ISO 27001 (international), PCI-DSS (payment card), HIPAA (health), GDPR (privacy), SOC 2 (trust services)
• Control Hierarchy: Policies → Procedures → Technical Controls; each level implements framework requirements
• Maturity Levels: Control maturity (ad-hoc, repeatable, defined, optimized); frameworks assess maturity
• Audit: External auditors verify controls map to requirements and are functioning

Instructions

1. Identify Applicable Frameworks:

   • NIST SP 800-53: Government contractors, critical infrastructure
   • CIS Controls: Universal baseline (applicable to all organizations)
   • ISO 27001: International standard; third-party certification available
   • PCI-DSS: Payment card processing organizations
   • HIPAA: Health information
   • GDPR: EU data processing
   • SOC 2 Type I/II: Service organizations; customer trust assurance
   • Document applicability rationale (regulatory requirement, customer requirement, industry standard)

2. Map Controls to Framework Requirements:

   • Control Catalog: Document all security controls (policies, procedures, technical controls)
   • Framework Requirements: For each framework, list all requirements
   • Mapping Table: Create matrix mapping controls to requirements (one control may address multiple requirements)
   • Gap Identification: Identify requirements with no corresponding control; prioritize implementation
   • Redundancy: Identify overlapping controls; consolidate where appropriate

3. Document Control Implementation:

   • Policy: Written policy defining requirement
   • Procedure: Step-by-step procedure for implementation
   • Evidence: Documentation, logs, screenshots proving control is operating
   • Responsibility: Owner (who ensures control operates?)
   • Testing: How is control validated? (audit, test, monitoring)

4. Plan Remediation for Gaps:

   • Severity Assessment: Critical gaps (high risk, customer requirement) vs. Medium/Low
   • Implementation Plan: Detailed plan to implement missing controls
   • Timeline: When will control be implemented? (Critical: <30 days)
   • Resource Allocation: Who owns implementation? What resources needed?
   • Validation: How will you verify control is operating post-implementation?

5. Maintain Mapping Over Time:

   • Annual Review: Frameworks evolve; review mapping annually
   • Control Updates: When control changes, update mapping
   • New Frameworks: If organization enters new regulated market, add frameworks
   • Audit Readiness: Maintain evidence of control operation (logs, testing results); provide to auditors

Anti-Patterns

• Mapping controls without understanding requirements; misalignment causes failed audits
• Assuming one control covers multiple requirements (false negatives); verify each requirement is covered
• Creating redundant controls; consolidate; reuse controls across frameworks
• Mapping controls that don't exist (paper controls); controls must be implemented and functioning
• No evidence collection; auditors require proof of control operation; plan evidence collection from the start
