What is the primary objective of ISO 27017?

ISO 27017 provides cloud-specific implementation guidance for 37 ISO 27002 controls plus 7 additional cloud-focused controls (CLD.6.3.1, CLD.8.1.5, CLD.9.5.1, CLD.9.5.2, CLD.12.1.5, CLD.12.4.5, CLD.13.1.4). Published in 2015, it addresses shared responsibilities between cloud service providers (CSPs) and cloud service customers (CSCs), covering multi-tenancy segregation, virtual machine hardening, asset removal/return, administrative operations security, customer monitoring, and network alignment in public, private, or hybrid clouds.

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. Professionally, it applies to CSPs operating IaaS/PaaS/SaaS and CSCs with significant cloud footprints, especially in regulated sectors demanding cloud assurance; adoption demonstrates due diligence in RFPs and procurement.

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

ISO 27017 does not support standalone third-party certification or require external audits. Controls are implemented and assessed within an ISO 27001 ISMS audit; certification bodies evaluate ISO 27017 guidance as an extension during ISO 27001 Stage 1/2 audits, often noting conformity in the certificate annex.

How often should an assessment for ISO 27017 be performed?

ISO 27017 assessments occur as part of annual ISO 27001 surveillance audits and triennial re-certification. Organizations perform internal reviews during management reviews, with continuous monitoring of cloud controls like logging and configurations to ensure ongoing 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 mandatory. Risks include failed RFPs, customer distrust, heightened breach exposure from unaddressed cloud risks (e.g., multi-tenancy failures), and regulatory scrutiny under data protection laws where cloud controls are expected.

An ISO 27017 be mapped to other international frameworks?

Yes, ISO 27017 controls map directly to international frameworks via its extension of ISO 27002. The 37 guidance controls and 7 CLD controls align with updated ISO 27001:2022 Annex A (93 controls), enabling integrated compliance without separate systems.

What is the first step to begin implementing ISO 27017?

Conduct a cloud-specific risk assessment within your ISO 27001 ISMS to identify applicable controls. Define scope for cloud services, document shared CSP/CSC responsibilities per CLD.6.3.1, and update the Statement of Applicability to include the 7 CLD controls and 37 extended ISO 27002 controls.

What is the primary objective of AS9110C?

AS9110C's primary objective is to define quality management system requirements for aviation maintenance, repair, and overhaul (MRO) organizations to ensure consistent conformity to customer and regulatory requirements while enhancing safety and airworthiness. It builds on ISO 9001:2015 using the High Level Structure, embedding aerospace-specific controls for configuration management, counterfeit parts prevention, human factors, traceability, and risk-based thinking across Clauses 4-10.

Who is legally or professionally required to comply with AS9110C?

AS9110C applies to MRO organizations performing maintenance on commercial, private, and military aircraft, including repair stations and OEM MRO divisions. It targets entities needing to demonstrate QMS capability for OASIS listing, customer contracts, or alignment with EASA/FAA Part-145, regardless of size, where aviation risks demand enhanced controls beyond ISO 9001.

Does AS9110C require an external audit or third-party certification?

Yes, AS9110C requires third-party certification through accredited registrars following Stage 1 (documentation review) and Stage 2 (on-site effectiveness audit). Internal audits and management review with 3+ months of operational data are prerequisites; certification is listed in IAQG OASIS for supply-chain recognition.

How often should an assessment for AS9110C be performed?

AS9110C assessments include annual surveillance audits post-certification and recertification every 3 years. Internal audits occur based on process risk (higher frequency for critical maintenance like configuration control); management reviews align with business cycles, using performance data from audits and KPIs.

What are the consequences of non-compliance with AS9110C?

Non-compliance with AS9110C risks loss of certification, exclusion from contracts, regulatory sanctions under FAA/EASA Part-145, and operational shutdowns. It leads to audit nonconformities, supply-chain rejection via OASIS, rework costs, safety incidents, fines up to $100k/day, and liability from airworthiness failures.

An AS9110C be mapped to other international frameworks?

Yes, AS9110C maps directly to ISO 9001:2015, as it is built upon its High Level Structure and core requirements. It also aligns with aviation regulatory frameworks like FAA and EASA Part-145, with internal clause-process matrices linking requirements like Clause 8 operational controls to maintenance processes.

What is the first step to begin implementing AS9110C?

The first step for AS9110C implementation is a formal gap analysis using clause-mapping checklists against existing processes and regulatory mappings (e.g., EASA/FAA Part-145). Secure executive sponsorship, define QMS scope, and produce a prioritized gap register to initiate phased planning with SOW and RACI.
