CrowdStrike has improved content update deployment control for its Falcon sensor after a faulty update caused system crashes on 8.5M Windows devices. The company has made several changes following a root cause analysis, including new test procedures and validation checks. Independent security vendors are reviewing its technology, and CrowdStrike has taken decisive steps to prevent future incidents.
Takeaways from the meeting notes:
– CrowdStrike is planning to give customers more control over deploying content updates for its Falcon sensor endpoint security technology, following a recent incident that led to a faulty update causing crashes on over 8.5 million Windows systems worldwide.
– The security vendor has implemented new features and made changes to its platform to support this capability, with additional functionality planned for the future.
– Multiple changes have been introduced by CrowdStrike, including new content configuration system test procedures, additional deployment layers, acceptance checks for its content configuration system, and new validation checks for updates.
– CrowdStrike has engaged two independent third-party security vendors to review the code for its Falcon sensor technology and the company’s quality control and release processes.
– The root cause of the incident was identified as a parameter count mismatch in the July 19 content configuration update, with the update containing 21 input fields instead of the expected 20, leading to an out-of-bounds memory read and system crashes.
– The parameter count mismatch was not detected during build validation, testing, or initial deployments due to the use of a “wildcard matching criteria” that accepted any value or no value at all for the extra input field’s parameter.
– CrowdStrike is facing lawsuits, including class-action lawsuits, over the incident, and is taking decisive steps to prevent similar situations in the future.
