Abstract
ISO/IEC 27002 "provides a reference set of generic information security controls including implementation guidance. [ISO/IEC 27002] is designed to be used by organisations: (a) within the context of an information security management system (ISMS) based on ISO/IEC27001; (b) for implementing information security controls based on internationally recognized best practices; [and] (c) for developing organisation-specific information security management guidelines.”
Introduction
ISO 27002 is a well-known standard around the world that lists all the best ways to control information security. ISO 27001 tells you what an Information Security Management System (ISMS) needs to do. ISO 27002, on the other hand, tells you how to put in place the security controls you need to keep sensitive information safe. Companies all over the world use ISO 27002 to improve their security, better manage risks, and make sure they follow the rules.
Scope of ISO 27002:2022
The standard includes a lot of different information security controls that can be used by businesses of all sizes and in all industries. It gives useful advice on how to put in place, keep up, and improve controls that keep information safe from unauthorized access, loss, or corruption. ISO/IEC 27002 covers policies, processes, and practices for human resources, physical security, access management, cryptography, and technology controls. This makes sure that organizations take a complete approach to information security.
Structure of the Standard
ISO 27002 organizes controls into multiple categories to simplify implementation. Key areas include:
- Organizational Controls – Governance, risk management, and security policies
- People Controls – Roles, responsibilities, training, and awareness
- Physical Controls – Facility security and equipment protection
- Technical Controls – Access management, encryption, and system hardening
This structured approach helps organizations align security controls with risk management strategies and ISMS requirements, ensuring consistency across all security activities.
Status
The first version of ISO 27002 came out in 2005, and there have been a few changes since then. The most recent major version came out in 2022. The 2022 edition gives new advice that takes into account today’s information security issues, such as cloud computing, cyber threats, and privacy concerns. It adds to ISO/IEC 27001 by giving detailed advice on how to put the controls in Annex A of ISO/IEC 27001 into action. This makes it an important resource for businesses that want to get or keep their certification.
Insights
When an organization puts ISO/IEC 27002 controls into place, its security posture can improve a lot. But there may be real-world problems, like figuring out how to use resources, training staff, and making controls fit the needs of the organization. Organizations should do regular assessments, put controls in order of risk, and add them to their ISMS for ongoing improvement. Businesses can lower security risks, follow the law, and build trust with stakeholders by following the advice in ISO/IEC 27002.
