    2016

    Aerospace quality management standard extending ISO 9001 requirements

    VS

    ISO 27018

    Voluntary
    2019

    International code of practice for PII protection in public clouds.

    Quick Verdict

    AS9100 ensures aerospace quality, safety, and supply chain integrity for aviation firms, while ISO 27018 protects PII in public clouds for service providers. Aerospace suppliers adopt AS9100 for OEM contracts; cloud operators pursue ISO 27018 to build customer trust and meet privacy regulations.

    AS9100 Details

    What It Is

    AS9100D (AS9100:2016) is a certification standard for quality management systems (QMS) in aviation, space, and defense. It extends ISO 9001:2015 with over 100 aerospace-specific requirements, focusing on safety-critical integrity via a process-based, risk-oriented approach using Annex SL structure.

    Key Components

    • Core clauses 4-10 covering context, leadership, planning, support, operation, evaluation, improvement.
    • Aerospace additions: configuration management (8.1.2), product safety (8.1.3), counterfeit prevention (8.1.4), operational risks (8.1.1), enhanced supplier controls.
    • Built on PDCA cycle; requires third-party certification via Stage 1/2 audits, annual surveillance.

    Why Organizations Use It

    • Meets OEM contractual mandates for market access.
    • Reduces defects, escapes, costs; improves delivery, supplier performance.
    • Manages high-consequence risks like safety events, counterfeits.
    • Builds trust via IAQG OASIS visibility, enhances competitiveness.

    Implementation Overview

    • Phased: gap analysis, process design, training, internal audits, certification (6-18 months).
    • Applies to manufacturers, designers, MROs globally; complex for SMEs due to supply chain scope.
    • Involves documented processes, risk registers, competence programs.

    ISO 27018 Details

    What It Is

    ISO/IEC 27018:2025 is an international code of practice extending ISO/IEC 27001 and ISO/IEC 27002 for protecting personally identifiable information (PII) in public clouds where providers act as PII processors. Its scope targets cloud-specific privacy risks like multi-tenancy and cross-border flows, using a risk-based approach within an Information Security Management System (ISMS).

    Key Components

    • Adds ~25–30 privacy-specific controls across organizational, people, physical, and technological domains.
    • Core principles: consent/choice, purpose limitation, data minimization, accuracy, retention/disclosure limits, security safeguards, transparency, accountability.
    • Maps to ISO 27001 Annex A; assessed via Statement of Applicability during certification audits—no standalone certification.

    Why Organizations Use It

    • Drives customer trust, procurement acceleration, regulatory alignment (GDPR, HIPAA).
    • Mitigates PII risks, enables subprocessor transparency, supports cyber insurance.
    • Provides market differentiation for cloud service providers (CSPs).

    Implementation Overview

    • Conduct gap analysis, integrate controls into ISMS, update contracts/policies.
    • Involves training, technical measures (encryption, logging), annual audits.
    • Suits CSPs globally; requires ISO 27001 base, accredited third-party validation.
