What is ISO 27001 Change Management?

ISO 27001 Annex A 8.32 Change Management is an ISO 27001 control that requires us to manage changes to both the information security management system (ISMS) and to the information processing facilities.

Purpose

ISO 27001 Annex A 8.32 is a preventive control to preserve information security when executing changes.

Definition

The ISO 27001 standard defines ISO 27001 Annex A 8.32 as:

Changes to information processing facilities and information systems should be subject to change management procedures.

Implementation Guide

Change management can be a profession in it’s own right and this control is no substitute for that. What we are going to do is manage our changes to the information processing facilities for in-scope products and services and we are going to manage changes to the information security management system.

Here we take a look at what the standard is wanting and how to implement it.

Change Management Policy

The first step is to create, or download, your change management policy. The ISO 27001 Change Management Policy set’s out what you do for change management It does not set out how you do it, as how you do it is covered in your processes.

The ISO 27001 Change Management Policy Template is the quickest way to do this but you can also take a look and write it yourself.
