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 for managing information security risks across confidentiality, integrity, and availability.
Key Components
- **Clauses 4-10Mandatory requirements covering 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 for continual improvement.
- Certification model via accredited auditors with Stage 1/2 audits, surveillance, and recertification.
Why Organizations Use It
- Enhances resilience against breaches, reduces incident costs (avg. $4.45M).
- Meets regulatory/contractual needs (GDPR, NIS2 alignments).
- Builds trust, wins bids (20-30% more in finance/tech).
- Drives efficiency, culture shift, insurance savings.
Implementation Overview
Phased approach: initiation, risk assessment, control deployment, audits (6-18 months). Scalable for all sizes/industries; voluntary but strategic for global compliance.
