ISO 27001 Details
What It Is
ISO/IEC 27001:2022 is the international certification standard for establishing, implementing, maintaining, and improving an Information Security Management System (ISMS). It provides a systematic, risk-based framework to manage information security risks across confidentiality, integrity, and availability.
Key Components
- **Clauses 4-10Mandatory requirements for context, leadership, planning, support, operation, evaluation, and improvement.
- **Annex A93 controls grouped into Organizational (37), People (8), Physical (14), and Technological (34) themes.
- Built on PDCA cycle and Annex SL for integration with ISO 9001/14001.
- Voluntary certification via accredited auditors with Stage 1/2 audits, surveillance, and 3-year recertification.
Why Organizations Use It
- Mitigates breaches, reduces costs (e.g., 30% fewer incidents), enables compliance (GDPR, NIS2).
- Builds trust, wins bids (20-30% more in finance/tech), provides insurance discounts.
- Strategic resilience across all sizes/industries.
Implementation Overview
Phased: initiation, risk assessment, control deployment (6-18 months). Scalable for SMEs/enterprises; requires leadership, audits, continual PDCA improvement.
AS9100 Details
What It Is
AS9100D (AS9100:2016) is the international quality management system (QMS) standard for aviation, space, and defense organizations. It builds on ISO 9001:2015 with over 100 aerospace-specific requirements, using a process-based, risk-based approach across 10 clauses aligned to Annex SL structure. Its primary purpose is ensuring product safety, configuration integrity, and supply chain reliability in high-consequence industries.
Key Components
- Core pillars: 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 risk (8.1.1), enhanced supplier controls.
- Built on ISO 9001 with PDCA cycle; certification via accredited third-party audits (Stage 1/2, surveillance).
Why Organizations Use It
- Market access: required by OEMs for supplier qualification.
- Risk reduction: prevents defects, safety events, counterfeit risks.
- Benefits: improved delivery, cost savings, OASIS visibility.
- Builds stakeholder trust through demonstrated integrity.
Implementation Overview
- Phased: gap analysis, process design, training, internal audits, certification.
- Applies to manufacturers, designers, MROs globally; 6-18 months typical.
- Evidence-driven audits ensure effectiveness.
