What you'll learn

On July 19 2024, CrowdStrike pushed an update to security sensors on customer networks. The update contained “problematic content” on Windows devices that wasn’t identified by its internal testing processes. This led to a Windows ‘Stop Error’, or Blue Screen of Death (BSOD), on any device that received the update. Companies worldwide ground to a halt - airports halted flights and hospitals postponed medical procedures. But why? In this course you’ll learn what went wrong, why the impact was so widespread, and how it was fixed. You’ll also understand why a relatively small update had such a significant impact, and what we can learn from this type of incident.
