ISO 27018 Details
What It Is
ISO/IEC 27018:2025 is an international 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 scope targets cloud-specific privacy risks like multi-tenancy and cross-border flows, using a risk-based approach integrated into an Information Security Management System (ISMS).
Key Components
- Privacy-specific controls (~25-30) on consent, transparency, data minimization, retention, and security.
- Aligned with principles: purpose limitation, accuracy, accountability.
- Assessed via ISO 27001 audits; no standalone certification.
- Maps to Annex A controls in organizational, people, physical, technological themes.
Why Organizations Use It
Enhances trust, accelerates procurement, aligns with GDPR Article 28, reduces cyber insurance friction. Offers competitive differentiation for CSPs, supports regulatory compliance, mitigates privacy risks in cloud outsourcing.
Implementation Overview
Conduct gap analysis against existing ISMS, update Statement of Applicability, implement transparency and breach procedures. Suitable for CSPs of all sizes; requires annual audits post-ISO 27001 certification. Focuses on contracts, subprocessors, data subject rights support.
ITIL Details
What It Is
ITIL (formerly Information Technology Infrastructure Library, now standalone since 2013) is a globally recognized best-practices framework for IT Service Management (ITSM). Its primary purpose is aligning IT services with business objectives through the full service lifecycle, emphasizing value co-creation. ITIL 4 (2019) uses a flexible, value-driven methodology via the Service Value System (SVS).
Key Components
The SVS includes guiding principles, governance, service value chain (6 activities), 34 practices (14 general, 17 service, 3 technical management), and continual improvement. Core elements encompass four dimensions (organizations & people, information & technology, partners & suppliers, value streams & processes) and 7 guiding principles (e.g., Focus on Value, Progress Iteratively). Certifications range from Foundation to Strategic Leader, managed by PeopleCert.
Why Organizations Use It
ITIL drives cost efficiencies, reduced downtime (e.g., 20% faster resolutions), 87% global adoption, risk mitigation (e.g., cyber resilience), and integration with DevOps/Agile. It boosts service quality, customer satisfaction, compliance (ISO 20000 alignment), and career growth, enhancing stakeholder trust and competitive edge.
Implementation Overview
Phased via **ten-step roadmappreparation, assessment, gap analysis, design, training. Tailorable for all organization sizes/industries; iterative pilots recommended. Voluntary certifications; no mandatory audits.
