ISO 27001 vs ISO 27002

Who is this for?

If you’re a compliance or IT leader evaluating ISO standards for your security program, this guide will help you understand the difference between ISO 27001 and ISO 27002, so you can align your organization with the right frameworks, reduce risk, and stay ahead of regulatory requirements.

Understanding ISO 27001 and ISO 27002 

ISO 27001 

ISO 27001 serves as the cornerstone of the ISO 27000 series, outlining the requirements for an Information Security Management System (ISMS). This standard provides a framework for managing sensitive company information through risk assessments, mitigation strategies, and continual improvement processes.

ISO 27001 is certifiable, which means organizations can demonstrate their commitment to security by achieving certification. This not only boosts trust among stakeholders but also enhances market competitiveness. The standard's mandatory clauses (4-10) define key ISMS requirements, while its Annex A lists recommended security controls to safeguard information assets.

ISO 27002

While ISO 27001 sets the “what” and “why” of information security management, ISO 27002 focuses on the “how.” Acting as a supplementary guideline, ISO 27002 provides detailed guidance for implementing the controls listed in ISO 27001’s Annex A.

Differences Between ISO 2001 & ISO 27002 

Though they work in harmony, ISO 27001 and ISO 27002 have key differences that influence their application.

Certification and Compliance

One of the most significant differences is certification. ISO 27001 allows organizations to achieve certification, showcasing their compliance with internationally recognized security standards. ISO 27002, however, doesn’t offer certification—it’s a guide meant to support ISO 27001’s implementation.

Risk Assessment Focus

ISO 27001 requires organizations to perform risk assessments to identify potential security threats and prioritize controls. This risk-driven approach ensures that security efforts are aligned with organizational needs. ISO 27002, on the other hand, skips risk assessment and focuses exclusively on providing control implementation details.

Structural Differences 

Structurally, ISO 27001 includes mandatory clauses covering management systems and a list of security controls in Annex A. ISO 27002 takes a deeper dive into these controls, providing a full page of guidance for each one. This detailed approach makes ISO 27002 an indispensable resource for organizations already implementing ISO 27001.

Steps for Successful Implementation

1. Assemble a dedicated team: Ensure you have skilled personnel with clear roles and responsibilities.
2. Conduct a gap analysis: Identify areas where your organization doesn’t meet ISO 27001 or ISO 27002 requirements.
3. Document processes: Maintain detailed records of your ISMS and control implementations.
4. Regular audits: Conduct internal audits to measure progress and identify improvement areas.
5. Train employees: Increase awareness and ensure everyone understands their role in maintaining security.
