How can organizations secure OT system updates without disrupting operations?

Organizations can secure Operational Technology (OT) system updates without disrupting operations by following these best practices:

1. Scheduled Maintenance Windows: Organizations can plan system updates during off-peak hours or scheduled maintenance windows to minimize disruptions to operations.

2. Testing in a Controlled Environment: Before deploying updates to live systems, organizations should thoroughly test them in a controlled environment to ensure compatibility and reduce the risk of issues.

3. Backup Systems: It’s essential to have backup systems in place so that in case an update causes issues, operations can smoothly transition to the backup systems while the problem is being resolved.

4. Segmentation of OT Networks: Segregating OT networks from other networks, such as IT networks, can isolate the impact of updates within the OT environment and prevent disruptions spreading to other parts of the organization.

5. Change Management Processes: Implementing robust change management processes ensures that updates are carefully planned, tracked, and communicated to relevant stakeholders, minimizing the chances of unexpected disruptions.

6. Monitoring and Response Plans: Continuous monitoring of OT systems helps identify any issues post-update quickly. Developing response plans for potential disruptions ensures a swift and effective resolution if any issues arise.

By following these guidelines, organizations can enhance the security of OT system updates while minimizing disruptions to their operations.
