ISO 22301 Details
What It Is
ISO 22301:2019 is an international certification standard for Business Continuity Management Systems (BCMS). It provides requirements to protect against, reduce likelihood of, respond to, and recover from disruptions, ensuring critical operations continue. Built on a risk-based PDCA (Plan-Do-Check-Act) approach with Annex SL high-level structure for easy integration.
Key Components
- 10 clauses (4-10 core): context, leadership, planning (BIA/risk assessment), support, operation (strategies/testing), evaluation (audits/reviews), improvement.
- No prescriptive controls; flexible, organization-specific.
- Core principles: resilience, continual improvement.
- 3-year certification with annual surveillance audits.
Why Organizations Use It
Enhances resilience, minimizes downtime/financial losses, ensures regulatory compliance (e.g., NIS Directive), builds stakeholder trust/reputation, provides competitive edges like procurement advantages and lower insurance premiums.
Implementation Overview
Gap analysis, BIA, policy development, training, testing, audits. Applies to all sizes/sectors globally. Typical 60 days to 6 months with tools; two-stage certification process.
ISO 27017 Details
What It Is
ISO/IEC 27017:2015 is a code of practice extending ISO/IEC 27002 with cloud-specific guidance. It provides implementation advice for information security controls in cloud services, focusing on public, private, and hybrid models across IaaS, PaaS, and SaaS. Its risk-based approach clarifies shared responsibilities between cloud service providers (CSPs) and customers (CSCs).
Key Components
- Guidance on 37 existing ISO 27002 controls adapted for cloud.
- Seven additional CLD cloud-specific controls (e.g., segregation, VM hardening, asset removal).
- Built on ISO 27001 ISMS framework.
- Assessed via ISO 27001 audits with 27017 scope extension; no standalone certification.
Why Organizations Use It
- Addresses cloud risks like multi-tenancy and shared responsibility.
- Supports regulatory compliance (e.g., GDPR via alignment).
- Enhances risk management and procurement trust.
- Provides competitive differentiation for CSPs and assurance for CSCs.
Implementation Overview
- Integrate into existing ISO 27001 ISMS via risk assessment and control mapping.
- Key activities: define responsibilities, configure virtualization controls, enable monitoring.
- Applicable to CSPs, CSCs across sizes/industries; global scope.
- Joint audits typically 9-12 months. (178 words)
