Recently, CrowdStrike faced an issue due to a small error in a software update that caused significant operational disruptions. This incident highlights the importance of careful patch management and thorough testing.

Understanding the Incident: The CrowdStrike incident was caused by a minor coding error in a software update that was incompatible with the Microsoft operating system. This defect, though easily rectified by deleting a single file, prevented affected computers from starting up. Such incidents underscore the critical need for rigorous testing and validation of updates before deployment.

Lessons for SMEs: For small and medium-sized enterprises (SMEs), this incident provides valuable lessons on avoiding similar issues. Here are key steps SMEs can take:

1. Implement a Robust Patch Management Strategy: Develop a comprehensive patch management policy that includes regular updates, prioritisation of critical patches, and a clear schedule for deployment.
2. Thorough Testing in a Staging Environment: Before rolling out patches to production systems, thoroughly test them in a staging environment. This helps identify potential incompatibilities and issues.
3. Backup Before Applying Patches: Always fully backup up systems before applying patches. This ensures that you can quickly restore functionality if something goes wrong.
4. Automate Patch Management: Utilise automated patch management tools to streamline the process, ensuring timely updates while minimising the risk of human error.
5. Monitor Systems Post-Deployment: Closely monitor systems after applying patches to detect and address any issues promptly. Automated monitoring tools can help identify and resolve problems quickly.
6. Maintain Vendor Communication: Keep open communication with software and hardware vendors to stay informed about the latest patches, known issues, and best practices for deployment.
7. Employee Training and Awareness: Train employees on the importance of patch management and how to report issues they may encounter after a patch is applied. An informed workforce can help quickly identify problems.
8. Develop an Incident Response Plan: Create and maintain an incident response plan that includes procedures for dealing with faulty patches. This plan should outline steps for rollback, communication, and resolution to minimise business impact.

Conclusion: The CrowdStrike incident serves as a reminder that even small errors in software updates can have significant consequences. By adopting a structured and cautious approach to patch management, SMEs can minimise the risk of operational disruptions and maintain smooth business operations.
