What is ISO 27001 Monitoring, Review and Change Management of Supplier Services?
ISO 27001 Monitoring, Review and Change Management of Supplier Services is the process of keeping an eye on and making changes to services you get from other companies, ensuring they’re secure. It’s about making sure your suppliers are following the security rules you’ve set, and that any changes to their services don’t create new risks for your business.
Context
When you hire a supplier, like a cloud provider or a company that manages your website, you need to be sure they handle your data safely. This control is about having a plan to regularly check what they’re doing and to manage any changesthey make. For example, if a supplier decides to upgrade their system, you need to know how that might affect the security of your data. This helps you prevent problems before they happen.
Examples
- Regular checks: Every three months, you review your cloud provider’s security reports to make sure they’re meeting their promises.
- Change control: Your payroll provider wants to switch to a new software system. You ask for a security assessment of the new system before they make the change.
- Performance review: You hold a meeting with your IT support company every six months to discuss their performance and any new security risks.
