ISO 27001 Annex A 8.32Change management procedures for information systems
Official control statement
Changes to information processing facilities and information systems shall be subject to change management procedures.
Quoted as published. Everything else on this page is written by Control Stack.
In plain English
Ensure all system changes follow a formal, approved process to prevent issues.
What this means in practice
Change management is about having a plan for updating or modifying your computer systems in a way that keeps everything working smoothly. Without it, you might accidentally disrupt your business or expose sensitive information to risks. Think of it like making sure you have a proper plan in place before rearranging an office - it prevents chaos.

Why it matters
Uncontrolled system changes can cause outages, introduce vulnerabilities, and lead to unplanned downtime, negatively impacting business operations.
Operational notes
Review change logs weekly; ensure IT and security assess risk and obtain approvals before implementing changes.
Implementation tips
- The IT manager should set up a formal change management process. They can do this by creating a checklist that includes planning, assessing the impact, obtaining authorisation, testing, and communicating changes. Following the ISO 27002:2022 guidelines ensures all potential risks are managed.
- The executive team needs to assign responsibility for approving changes. This means choosing someone who understands both the business and technical sides to review every planned change and give the green light if it meets all security and operational requirements.
- IT staff should document each step in the change management process. By keeping detailed records of what changes were made, who approved them, and any testing results, you create a clear trail. This documentation helps ensure consistency and can protect against future issues if something goes wrong.
- Operations personnel need to communicate upcoming changes to everyone in the organisation. They should send out emails or hold meetings to explain upcoming changes, how they could affect work, and what the timeline is.
- The IT department should integrate all change management procedures with existing IT policies. This involves ensuring change management aligns with broader IT and cyber security frameworks like the ASD Essential Eight and ensures business continuity plans are updated as per ISO standards.
Audit / evidence tips
- AskRequest the change log or change management documentation.Look atCheck that the log includes entries for planning, authorisation, testing, communication, and implementation steps.GoodA complete and organised log with no missing sections, proving each step was followed and recorded.
- AskRequest records of change management meetings or communications.Look atLook for meeting minutes or emails that confirm changes were discussed and communicated to relevant parties.GoodDetailed records showing that each change was clearly communicated and that all stakeholders were informed ahead of implementation.
- AskAsk for test results documentation for implemented changes.Look atVerify that tests were conducted before changes went live and that results were analysed.GoodComprehensive test result documents showing that potential impacts were evaluated and confirmed successful before deployment.
- AskRequest the authorisation records for recent changes.Look atVerify that each entry includes a clear authorisation signature or record from management.GoodAll changes have a designated approver's sign-off, showing the decision-making process was appropriately followed.
- AskDemand evidence of updated operational documentation.Look atCheck if updates reflect recent system changes and align with the implementation guidelines.GoodUpdated guides or manuals that align with the most recent system changes, demonstrating that users have the latest instructions.
