What is the difference between ISO 27001 and 27002

The International Organization for Standardization (ISO) has developed a set of standards to help organizations establish, implement, maintain, and continuously improve their information security management systems. Two widely known standards are ISO 27001 and ISO 27002. While these two standards are related, they serve different purposes. This article aims to provide a thorough understanding of the differences between ISO 27001 and ISO 27002.

ISO 27001: Information Security Management Systems (ISMS)

ISO 27001 sets out the criteria for an organization to establish, implement, operate, monitor, review, maintain, and continually improve an Information Security Management System (ISMS). It provides a structured framework for organizations to manage their information security risks systematically. Compliance with ISO 27001 demonstrates that an organization has adopted internationally recognized best practices for information security management. The standard covers a wide range of areas, including risk assessment and treatment, information security policy, asset management, access control, and incident management.

ISO 27002: Code of Practice for Information Security Controls

ISO 27002, on the other hand, provides guidance on implementing controls to address the risks identified in ISO 27001. It consists of a comprehensive list of security controls that organizations can choose to implement based on their specific needs and risk assessments. ISO 27002 covers various areas such as physical security, network security, human resource security, cryptography, and business continuity management. By adopting ISO 27002, organizations can ensure the confidentiality, integrity, and availability of their information assets.

Differences between ISO 27001 and ISO 27002

1. Focus: ISO 27001 focuses on the establishment and management of an information security management system, while ISO 27002 focuses on providing a set of best practice controls for implementing the necessary security measures.

2. Structure: ISO 27001 is a standard with specific requirements that organizations must meet to achieve certification. ISO 27002 is a code of practice that provides guidelines and recommendations for implementing security controls but does not offer certification.

3. Flexibility: ISO 27001 allows organizations to tailor their information security management system to fit their unique requirements and risk profile. ISO 27002 provides a framework of suggested controls that organizations can select from based on their specific needs and risk assessments.

4. Coverage: ISO 27001 covers all aspects of information security management, including the organizational context, risk assessment, compliance, and continual improvement. ISO 27002 focuses on the implementation of security controls, detailing specific measures for different areas of information security.

Conclusion

In conclusion, ISO 27001 and ISO 27002 are closely related standards that work together to establish robust information security management systems. While ISO 27001 sets the requirements for building an effective ISMS, ISO 27002 provides guidance on implementing controls to mitigate information security risks. By adopting these standards, organizations can protect their valuable information assets and demonstrate their commitment to maintaining high levels of information security.
