Extending to Other Standards

Extending to Other Standards

ISO 27001 is often the foundation for broader compliance strategy.

Common Standards

Information Security: ISO 27001, SOC 2, ISO 27017/27018

Privacy: GDPR, CCPA, ISO 27701

Industry: PCI DSS, HIPAA, FedRAMP, HITRUST

General: ISO 9001, ISO 14001, NIST CSF

ISO Management System Family

Common High-Level Structure (Annex SL): All ISO management systems share common framework (10 clauses).

Benefit: If you have ISO 27001, you're 60-70% toward other ISO management systems.

Natural Extensions:

• ISO 27002: Control implementation guidance
• ISO 27017: Cloud services security
• ISO 27018: Cloud PII protection
• ISO 27701: Privacy management (PIMS)

Integration Strategies

Strategy 1: Sequential

• Year 1: ISO 27001
• Year 2: SOC 2
• Year 3: ISO 27701
• Best for moderate resources

Strategy 2: Parallel

• ISO 27001 + SOC 2 together
• Faster but resource intensive

Strategy 3: Modular

• Core: ISO 27001
• Add modules as needed
• Flexible timing

Unified Control Framework

Create control matrix mapping standards:

• Single policy per control area
• Reference all applicable standards
• Shared evidence repository
• Tag evidence by standard

Practical Extensions

ISO 27001 → ISO 27701 (Privacy)

• Add: PII risk assessment, data subject rights, PIAs
• Effort: 2-4 months
• Audit add-on: 1-2 days

ISO 27001 → SOC 2

• Add: Detailed testing, system description, continuous evidence
• Effort: 3-6 months
• Annual audit: 3-5 days

ISO 27001 → PCI DSS

• Add: Card data controls, quarterly scans, pen testing
• Effort: 4-8 months

ISO 27001 → FedRAMP

• Add: NIST 800-53 controls, continuous monitoring
• Effort: 12-24 months (significant)

Resource Planning

Staffing:

• 1 framework: 0.5-1.0 FTE
• 2 frameworks: 1.0-2.0 FTE
• 3+ frameworks: 1.5-3.0 FTE + specialists

Budget:

• Audit costs: Variable per framework
• Tools: $15K-$75K/year (multi-framework GRC)
• Consulting: $10K-$30K per gap assessment

Avoiding Framework Fatigue

Prevention:

1. Prioritize strategically
2. Sequence appropriately
3. Resource adequately
4. Automate aggressively
5. Celebrate progress

Rule: Add max one major framework per year

Decision Framework

Evaluate new standard:

1. Customer demand?
2. Market access?
3. Regulatory requirement?
4. Overlap with existing?
5. Resource capacity?
6. ROI?
7. Timeline urgency?

Start with ISO 27001 as foundation, add strategically based on business needs, integrate relentlessly.

Don't collect certifications like Pokemon: Right certifications maintained well > many done poorly.
