Change Management (CM)
Change Management in cybersecurity involves the systematic approach to dealing with change, both from the perspective of an organization and the individual. A well-designed change management plan can help prevent security lapses during the transition process.
Here are some best practices for Device Change Management:
- Configuration Benchmark: The use of configuration checklist provided by some of the frameworks can protect an organization from disruptions. Search for your device benchmark from CISECURITY and implement gradually, remember, all of the checklist cannot be installed right away.
- Document Changes: Keep a record of all changes made to the device configurations. This includes what was changed, why it was changed, who changed it, and when it was changed.
- Test Changes: Before implementing any changes in the live environment, test them in a controlled environment to understand their impact.
- Backup Configurations: Always backup device configurations before making changes. This will allow you to restore the previous state if something goes wrong.
- Approval Process: Implement a formal approval process for changes. This ensures that changes are reviewed and approved by the appropriate personnel before they are implemented.
- Monitor and Audit: Regularly monitor and audit device configurations to detect any unauthorized changes.
- Training: Ensure that the team responsible for device change management is adequately trained and understands the potential impact of the changes.
Device change management can help prevent downtime, improve system performance, and enhance security. It’s not a one-time project but an ongoing process that needs to be continually reassessed and updated to meet the evolving IT landscape.
