ISO/IEC 27001:2022 – Information Security Management System (ISMS)

1. Definition

ISO/IEC 27001:2022 is the international standard for Information Security Management Systems (ISMS).
It provides a systematic framework for establishing, implementing, maintaining, and continually improving information security within an organization.

The 2022 revision modernizes the control structure and integrates with digital transformation, cloud computing, and cybersecurity trends, replacing ISO/IEC 27001:2013.

2. Purpose and Scope

The primary objectives of ISO/IEC 27001:2022 are to:

  • Protect confidentiality, integrity, and availability of information.

  • Ensure compliance with legal, contractual, and regulatory obligations.

  • Manage risks associated with cyber threats, data breaches, and unauthorized access.

  • Promote trust and resilience across digital and physical information assets.

The standard applies to all types of organizations handling data — from government agencies and financial institutions to manufacturing firms and IT service providers.
