ISO 27017 Details
What It Is
ISO/IEC 27017:2015 is a code of practice extending ISO/IEC 27002 for cloud services. It provides implementation guidance for information security controls in cloud environments, focusing on public, private, and hybrid deployments across IaaS, PaaS, and SaaS. Its risk-based approach integrates with ISO 27001 ISMS, adding cloud-specific adaptations.
Key Components
- Guidance on 37 ISO 27002 controls tailored for cloud.
- Seven additional CLD controls (e.g., shared responsibilities, VM segregation, asset removal).
- Domains mirror ISO 27002: access control, operations, supplier relationships.
- No standalone certification; assessed within ISO 27001 audits.
Why Organizations Use It
Enhances cloud risk management, clarifies CSP-CSC responsibilities, supports GDPR/CCPA compliance. Builds trust with stakeholders, aids procurement, differentiates CSPs in competitive markets.
Implementation Overview
Integrate into existing ISO 27001 ISMS via risk assessment, control mapping, and documentation updates. Applies to CSPs, CSCs across sizes/industries; involves configuration hardening, monitoring setup. Joint audits take 9-12 months.
CIS Controls Details
What It Is
CIS Critical Security Controls v8 is a community-driven, prescriptive cybersecurity framework of prioritized best practices to reduce cyber risks and enhance resilience. It focuses on 18 controls with 153 actionable safeguards, using an offense-informed, risk-prioritized approach scalable via Implementation Groups (IG1–IG3).
Key Components
- 18 Controls covering asset inventory, data protection, vulnerability management, incident response, and more.
- 153 Safeguards decomposed into testable tasks.
- Built on real-world attack data; maps to NIST, ISO 27001, HIPAA.
- No formal certification; self-assessed compliance via tools like CIS Navigator.
Why Organizations Use It
- Mitigates 85% of common attacks; accelerates regulatory compliance.
- Delivers ROI via reduced breaches, operational efficiency, insurance discounts.
- Builds trust with partners, regulators; competitive edge in procurement.
Implementation Overview
- Phased roadmap: governance, discovery, foundational controls (IG1), expansion (IG2/IG3).
- Applies to all sizes/industries; automation-heavy for scalability.
- Metrics-driven with KPIs; ongoing audits, no mandatory certification. (178 words)
