What is the primary objective of **ISO 27017**?

**ISO 27017 provides implementation guidance for applying **ISO 27002** controls in cloud environments and introduces **seven additional cloud-specific controls** (identified as CLD controls).** Published in 2015, it addresses shared responsibilities between **cloud service providers (CSPs)** and **cloud service customers (CSCs)**, focusing on multi-tenancy, virtual machine configuration, segregation, asset return/termination, and customer monitoring of cloud activities.

Who is legally or professionally required to comply with **ISO 27017**?

**No organization is legally required to comply with **ISO 27017**, as it is a voluntary code of practice, not a mandatory regulation.** Professionally, it applies to **CSPs** operating cloud services and **CSCs** using public, private, or hybrid clouds across IaaS, PaaS, and SaaS models, particularly those integrating it into an **ISO 27001** ISMS to demonstrate cloud security maturity.

Does **ISO 27017** require an external audit or third-party certification?

**ISO 27017 does not support standalone third-party certification or require a separate external audit.** It is implemented within an **ISO 27001** ISMS, where auditors assess its **37 extended controls** from **ISO 27002** and **seven CLD controls** during **ISO 27001** Stage 1 and Stage 2 audits, often noted as an extension on the certificate.

How often should an assessment for **ISO 27017** be performed?

**Assessments for **ISO 27017** controls occur as part of **ISO 27001** surveillance audits, typically annually.** Re-certification audits, including **ISO 27017** evaluation, are required every three years, with continuous monitoring of cloud configurations recommended to maintain control effectiveness.

What are the consequences of non-compliance with **ISO 27017**?

**Non-compliance with **ISO 27017** carries no direct legal penalties, as it is not enforceable law.** Indirect consequences include increased cloud security risks (e.g., multi-tenant breaches), failure to meet customer procurement demands, regulatory scrutiny under data protection laws, and loss of **ISO 27001** certification if cloud controls are inadequately addressed.

Can **ISO 27017** be mapped to other international frameworks?

**Yes, **ISO 27017** controls can be mapped to frameworks like NIST SP 800-53 and CSA STAR for cross-compliance.** Its **37 guidance controls** from **ISO 27002** and **seven CLD controls** align with shared-responsibility models in FedRAMP and PCI-DSS cloud requirements, enabling unified evidence collection.

What is the first step to begin implementing **ISO 27017**?

**The first step to implement **ISO 27017** is to conduct a cloud-specific risk assessment within your **ISO 27001** ISMS scope.** Identify cloud risks (e.g., shared responsibilities via CLD.6.3.1), then update the Statement of Applicability to select relevant **ISO 27002** controls and the **seven CLD controls**.

What is the primary objective of **ITIL**?

**The primary objective of ITIL is to align IT services with business objectives through its Service Value System (SVS), enabling value co-creation via 34 practices, guiding principles, governance, and continual improvement.** ITIL 4 (2019) emphasizes the four dimensions—organizations & people, information & technology, partners & suppliers, value streams & processes—to deliver services that are fit for purpose (utility) and fit for use (warranty), optimizing resource utilization and service quality.

Who is legally or professionally required to comply with **ITIL**?

**No organizations are legally required to comply with ITIL, as it is a voluntary set of best-practice guidelines for IT Service Management (ITSM), not a mandatory regulation.** Professionally, IT leaders, service managers, and ITSM practitioners in enterprises adopt it voluntarily, with 87% global IT organizations using it for alignment; certifications via PeopleCert (Foundation to Strategic Leader) are recommended for roles like Service Owner and Process Owner.

Does **ITIL** require an external audit or third-party certification?

**ITIL does not require external audits or third-party certification, as it is a framework of best practices without formal certification mandates.** Organizations may pursue voluntary ISO/IEC 20000 certification, which aligns with ITIL practices, but ITIL itself focuses on internal adoption of its 34 practices and SVS; PeopleCert manages practitioner certifications, not organizational audits.

How often should an assessment for **ITIL** be performed?

**ITIL assessments should be performed continuously as part of the Continual Improvement practice within the SVS, with formal gap analyses conducted during initial implementation and periodically thereafter.** The ten-step roadmap recommends an initial ITIL-Assessment (Step 4) for baseline, followed by iterative reviews using the seven-step improvement process to measure KPIs like incident resolution times and change success rates.

What are the consequences of non-compliance with **ITIL**?

**There are no legal consequences for non-compliance with ITIL, since it is a non-mandatory framework; potential business impacts include suboptimal service delivery, higher costs, and increased downtime.** Adopters missing its practices risk inefficiencies like unaligned IT-business objectives or failure to leverage 34 practices for risk mitigation, but no fines or penalties apply.

Can **ITIL** be mapped to other international frameworks?

**Yes, ITIL can be mapped to other international frameworks, with its practices and SVS designed for integration with models like Agile, DevOps, Lean, and standards such as ISO/IEC 20000.** The 34 practices (14 general, 17 service, 3 technical) align via shared processes like incident management and continual improvement, enabling hybrid adoption without prescriptive conflicts.

What is the first step to begin implementing **ITIL**?

**The first step to begin implementing ITIL is Project Preparation, securing executive sponsorship and defining scope as outlined in the ten-step roadmap.** This involves developing a business case to quantify benefits like ROI (e.g., up to 38:1), followed by role definition for practices like Change Enablement and Service Desk.
