Explanation
The standard definition of ISMS is a systematic approach for establishing, implementing, operating, monitoring, reviewing, maintaining and improving an organization's information security to achieve business objectives. This definition is given in clause 3.17 of ISO/IEC 27001:2022, and it describes the main components and purpose of an ISMS. An ISMS is not a project-based approach, as it is an ongoing process that requires continual improvement. An ISMS is not a company wide business objective, as it is a management system that supports the organization's objectives. An ISMS is not an information security systematic approach, as it is a broader concept that encompasses the organization's context, risks, controls, and performance.
