Introduction
The Information Security Management System (ISMS) policy is a cornerstone document that guides an organization's information security initiatives.
According to ISO/IEC 27001:2022, particularly Clause 5.2, the ISMS policy must align with the standard's requirements to effectively support the organization's information security objectives.
This article outlines how to ensure that the ISMS policy is aligned with ISO/IEC 27001:2022, based on the guidelines provided in ISO/IEC 27003:2017.

An ISMS policy establishes the framework and principles for managing information security within an organization.
It communicates the management's commitment to information security, outlines the security objectives, and provides a high-level overview of how these objectives will be achieved.
A well-crafted ISMS policy ensures that the organization's approach to information security is coherent, comprehensive, and aligned with business goals.
