ISO 27032 Details
What It Is
ISO/IEC 27032:2023, titled Cybersecurity – Guidelines for Internet Security, is an international guidance standard providing non-certifiable recommendations for securing Internet ecosystems. Its primary purpose is to enhance cybersecurity through multi-stakeholder collaboration, addressing risks in interconnected digital environments. It uses a risk-based approach, linking Internet security to information, network security, and critical infrastructure protection.
Key Components
- Core elements include stakeholder roles, risk assessment, incident management, technical/organizational controls.
- Features Annex A mapping threats to ISO/IEC 27002 controls (93 total).
- Built on principles of collaboration, trust, PDCA cycle.
- No certification; integrates into ISO 27001 ISMS via Statement of Applicability.
Why Organizations Use It
Adoption reduces breach risks, improves resilience, and aligns with regulations like NIS2/GDPR. Benefits include operational efficiency, stakeholder trust, competitive differentiation, and insurance savings. It addresses ecosystem threats like DDoS/phishing.
Implementation Overview
Follow phased approach: scoping, gap analysis, controls deployment, monitoring. Suited for all sizes/industries with online presence. Key activities: stakeholder mapping, training, audits. No formal certification required.
ISO 27018 Details
What It Is
ISO/IEC 27018 is a code of practice extending ISO 27001 and ISO 27002 for protecting personally identifiable information (PII) in public clouds where providers act as PII processors. Its primary purpose is to provide privacy-specific controls addressing cloud challenges like multi-tenancy and cross-border data flows. It follows a risk-based approach, integrating ~25-30 additional controls into an Information Security Management System (ISMS).
Key Components
- Core areas: consent, purpose limitation, data minimization, transparency, accountability, subprocessor management, breach notification.
- Built on ISO 27001 Annex A (93 controls) with cloud-PII guidance.
- Principles: aligns with GDPR Article 28, OECD guidelines.
- Certification via ISO 27001 audits; no standalone certificate.
Why Organizations Use It
- Builds customer trust, accelerates procurement, supports regulatory compliance (GDPR, HIPAA).
- Reduces risk in cloud outsourcing, favors cyber insurance terms.
- Differentiates CSPs in competitive markets.
Implementation Overview
- Gap analysis against existing ISMS, policy updates, technical controls (encryption, logging).
- Applicable to CSPs of all sizes; annual audits post-certification.
- Focuses on processors; controllers map to contracts.
