ISO 27001 Details
What It Is
ISO/IEC 27001:2022 is an international certification standard for establishing, implementing, maintaining, and improving an Information Security Management System (ISMS). It uses a risk-based approach to manage information assets' confidentiality, integrity, and availability across any organization.
Key Components
- **Clauses 4-10Mandatory requirements for context, leadership, planning, support, operation, evaluation, and improvement.
- **Annex A93 controls in four themes (Organizational: 37, People: 8, Physical: 14, Technological: 34).
- Built on PDCA cycle for continual improvement.
- Statement of Applicability (SoA) justifies control selection.
Why Organizations Use It
- Enhances resilience against breaches, reduces costs (e.g., 30% fewer incidents).
- Meets regulatory/contractual needs (e.g., GDPR alignment).
- Builds trust, wins bids (20-30% more in finance/tech).
- Provides competitive edge via certification.
Implementation Overview
- Phased: initiation, risk assessment, deployment, certification (6-18 months).
- Applies to all sizes/industries; voluntary but strategic.
- Requires audits: Stage 1 (docs), Stage 2 (effectiveness), annual surveillance.
TOGAF Details
What It Is
The TOGAF® Standard (The Open Group Architecture Framework) is a vendor-neutral enterprise architecture framework for designing, planning, implementing, and governing business-IT alignment. Its primary scope spans enterprise-wide change, using an iterative Architecture Development Method (ADM) as the core methodology.
Key Components
Key pillars include the ADM (10 phases: Preliminary to Change Management, plus Requirements Management); Content Framework (deliverables, artifacts like catalogs/matrices/diagrams, building blocks); Enterprise Continuum for asset classification/reuse; Reference Models (TRM, SIB, III-RM); and Architecture Capability Framework (governance, skills, maturity). Built on reusable, traceable metamodels; offers practitioner certification.
Why Organizations Use It
TOGAF drives strategy-IT alignment, cost reduction via reuse, ROI improvement, risk mitigation, and vendor neutrality. It meets no legal mandates but enables governance, compliance (e.g., via traceability), agility, and stakeholder trust in complex environments.
Implementation Overview
Tailored, phased ADM rollout: maturity assessment, governance setup (Architecture Board), pilots, scaling. Suited for large enterprises across industries globally; involves training, repository buildout. Voluntary, no org certification.
