ISO 27017 Details
What It Is
ISO/IEC 27017:2015 is a code of practice extending ISO/IEC 27002 with cloud-specific information security controls. It provides implementation guidance for 37 existing controls and adds 7 new cloud-focused controls (CLD series), targeting public, private, and hybrid clouds across IaaS, PaaS, SaaS. Its risk-based approach integrates into ISO 27001 ISMS for CSPs and CSCs.
Key Components
- Domains mirror ISO 27002: policies, access, operations, supplier relationships.
- Core **CLD controlsshared responsibilities (CLD.6.3.1), VM segregation (CLD.9.5.1), hardening (CLD.9.5.2), admin ops, monitoring, asset removal.
- Built on ISO 27001/27002; no standalone certification—assessed via ISO 27001 audits.
Why Organizations Use It
Enhances cloud risk management, clarifies shared duties, meets procurement demands, supports GDPR/CCPA alignment. Builds trust, differentiates CSPs, reduces incidents from misconfigurations.
Implementation Overview
Integrate into existing ISO 27001 ISMS via risk assessment, control mapping, tooling for monitoring. Applies to all sizes with cloud use; joint audits take 9-12 months.
ISO 27701 Details
What It Is
ISO/IEC 27701:2025 is the international standard for establishing, implementing, maintaining, and improving a Privacy Information Management System (PIMS). It extends ISO 27001 with privacy-specific requirements for PII controllers and processors, using a risk-based, PDCA management system approach to manage privacy risks.
Key Components
- Clauses 4–10 for management system (context, leadership, planning, operation, evaluation, improvement)
- **Annex AControls for PII controllers (e.g., lawful basis, DSARs, retention)
- **Annex BControls for PII processors (e.g., contracts, sub-processors)
- Mappings to GDPR (Annex D), ISO 27002; ~50 privacy controls
- Certification via accredited bodies, 3-year cycle with surveillance audits
Why Organizations Use It
- Demonstrates accountability for global privacy laws (GDPR, CCPA)
- Reduces risks from breaches, fines; builds supply-chain trust
- Enables procurement differentiation, regulatory evidence
- Integrates privacy into security governance for efficiency
Implementation Overview
- Phased: scope PII flows, gap analysis, controls, audits
- Applies to all sizes/sectors handling PII; 6–18 months typical
- Requires RoPA, DPIAs, training; integrates with ISMS (184 words)
Key Differences
| Aspect | ISO 27017 | ISO 27701 |
|---|---|---|
| Scope | Cloud-specific security controls, shared responsibility | Privacy management system for PII controllers/processors |
| Industry | Cloud providers/customers, all sectors globally | PII-processing organizations worldwide, all sizes |
| Nature | Guidance code of practice, ISO 27001 extension | PIMS standard, certifiable with/without ISO 27001 |
| Testing | Assessed in ISO 27001 audits, no standalone cert | Integrated/standalone audits, 3-year cycle surveillance |
| Penalties | Loss of ISO 27001 certification, no direct fines | Certification loss, supports regulatory fine avoidance |
