ISO 17025 Details
What It Is
ISO/IEC 17025:2017 is the international standard specifying general requirements for the competence, impartiality, and consistent operation of testing and calibration laboratories. It is an accreditation framework (not certification) focused on technical validity of results through risk-based, performance-oriented controls.
Key Components
- Eight main clauses: general (impartiality/confidentiality), structural, resource, process, and management system requirements.
- Core elements include metrological traceability, measurement uncertainty, method validation, personnel competence, and proficiency testing.
- Built on risk-based thinking; Option A/B for management systems (standalone or ISO 9001-aligned).
- Accreditation by ILAC-recognized bodies attests to defined scope competence.
Why Organizations Use It
- Ensures market access, regulatory acceptance, and stakeholder trust in results.
- Mitigates risks of invalid data impacting safety, compliance, and trade.
- Provides competitive edge via global recognition; often contractually required.
Implementation Overview
- Phased PDCA approach: gap analysis, documentation, training, validation, audits.
- Applies to labs of all sizes in testing/calibration; 18-24 months typical.
- Involves accreditation assessments with witnessed activities and ongoing surveillance.
ISO 27017 Details
What It Is
ISO/IEC 27017:2015 is a code of practice extending ISO/IEC 27002 for information security controls in cloud services. It provides guidance for CSPs and CSCs, focusing on cloud-specific risks like multi-tenancy and shared responsibilities. Its risk-based approach integrates with ISO 27001 ISMS.
Key Components
- Guidance on 37 ISO 27002 controls adapted for cloud.
- 7 additional CLD controls (e.g., segregation, VM hardening, asset removal).
- Built on ISO 27001/27002; no standalone certification.
- Domains mirror ISO 27002: access, operations, supplier relationships.
Why Organizations Use It
- Addresses shared responsibility gaps in cloud.
- Meets procurement, regulatory demands (e.g., GDPR alignment).
- Enhances risk management, reduces incidents.
- Builds stakeholder trust, competitive edge for CSPs/CSCs.
Implementation Overview
- Integrate into ISO 27001 via risk assessment, SoA updates.
- Key activities: control mapping, configuration hardening, contracts.
- Applies to all sizes/industries using cloud; global scope.
- Audited as ISO 27001 extension (9-12 months joint).
