ISO/IEC 27001
The Global Standard for Information Security Management.
ISO 27001 is the premier international standard for managing information security. It provides a systematic approach for establishing, implementing, maintaining, and continually improving an Information Security Management System (ISMS).
An ISMS is a comprehensive approach to managing sensitive company information so that it remains secure. It includes people, processes and IT systems by applying a risk management process.
- Type: Security Framework
- Core Idea: Risk-based Information Security Management
- Key Elements: ISMS, Annex A Controls, Risk Assessment
Core Components
Understanding the structure of ISO 27001.
Applicability
Universal; any organization, regardless of size, industry, or location. Particularly valuable for international business.
Status
Voluntary, but often a contractual requirement for enterprise and government supply chains.
Core Requirement
A formal, documented risk assessment and treatment process, supported by a selection of 93 controls from Annex A.
Output
A pass/fail certification confirming the ISMS is compliant.
Perception
The international gold standard for a mature, holistic security program. Builds significant trust, especially in Europe and Asia.
Implementation & Strategy
Costs, timelines, and strategic considerations for adopting ISO 27001.
Estimated Project Costs
ISO 27001 certification costs can vary widely, depending on the size and complexity of the organization. A small organization might spend between $10,000 and $30,000, while a mid-sized organization could spend between $30,000 and $100,000. Large, enterprise-level organizations can exceed $100,000.
Implementation Strategy
A typical ISO 27001 implementation starts with a gap analysis to identify the organization's current security posture. From there, the organization can develop a risk treatment plan and implement the necessary controls. The final step is to undergo a formal audit by a certification body.
