What is the Difference between ISO 27001 and 27002?

The ISO 27001 and ISO 27002 are both internationally recognized standards that deal with information security management. While these two standards are related, they have distinct differences in their scope and focus. In this article, we will explore the disparities between ISO 27001 and ISO 27002.

ISO 27001: Information Security Management System

ISO 27001 is a standard that outlines the requirements for establishing, implementing, maintaining, and continually improving an information security management system (ISMS). This standard provides a systematic approach to managing sensitive company information, ensuring its confidentiality, integrity, and availability.

ISO 27001 focuses on the overall management of information security within an organization. It provides guidelines for identifying risks, selecting appropriate security controls, and establishing processes to monitor, maintain, and improve information security.

Complying with ISO 27001 demonstrates an organization's commitment to protecting its information assets and reducing the risk of security breaches. Certification against ISO 27001 is proof that an organization has implemented best practices and controls to safeguard its sensitive information.

ISO 27002: Code of Practice for Information Security Controls

ISO 27002, previously known as ISO 17799, is a code of practice that provides detailed guidance for implementing specific security controls listed in ISO 27001. This standard helps organizations select and implement appropriate security measures to address identified risks.

ISO 27002 covers a wide range of security topics, including organizational security, human resource security, physical and environmental security, communications and operations management, access control, information systems acquisition, development, and maintenance, and more. It serves as a comprehensive guide for organizations looking to establish their information security controls.

While ISO 27001 is the standard for setting up an ISMS, ISO 27002 offers detailed control objectives and implementation guidance. Organizations can use ISO 27002 as a reference to ensure they have appropriate controls in place to manage their information security risks effectively.

The Relationship between ISO 27001 and ISO 27002

ISO 27001 and ISO 27002 are closely related and should be seen as complementary standards. ISO 27001 provides the framework for designing and implementing an effective information security management system, while ISO 27002 offers specific guidance on which controls to implement.

Organizations typically start by implementing ISO 27001, defining the scope, assessing risks, and establishing the necessary processes and controls. ISO 27002 can then be used to dive deeper into each control category, providing organizations with additional guidance on how to implement the controls effectively.

It's important to note that while compliance with ISO 27001 is auditable and certifiable, ISO 27002 is not certifiable as a standalone standard. However, organizations can undergo an audit against ISO 27001 and demonstrate compliance with ISO 27002 by implementing its recommended controls.

In conclusion, ISO 27001 focuses on the overall management of information security through the implementation of an ISMS, while ISO 27002 provides guidance on specific controls to be implemented within the ISMS framework. Both standards play a crucial role in helping organizations protect their valuable information assets from potential threats and vulnerabilities.
