In the wake of recent challenges, the focus on software resiliency and testing has never been more critical. To prevent similar incidents from occurring in the future, several strategic measures are being implemented.
Enhancing Rapid Response Content Testing
Improving the rapid response content testing process involves utilizing various testing types:
- Local developer testing: Ensuring that content is thoroughly vetted at the developer level.
- Content update and rollback testing: Verifying that updates can be smoothly implemented and reverted if necessary.
- Stress testing, fuzzing, and fault injection: Pushing the system to its limits to identify potential weaknesses.
- Stability testing: Confirming that the system remains stable under various conditions.
- Content interface testing: Ensuring seamless interaction between different content components.
Additional validation checks are being added to the Content Validator for Rapid Response Content. A new check is currently in process to prevent problematic content from being deployed in the future. Moreover, existing error handling in the Content Interpreter is being enhanced to better manage unexpected issues.
Strategic Rapid Response Content Deployment
A staggered deployment strategy for Rapid Response Content is being implemented. This approach involves gradually deploying updates to larger portions of the sensor base, starting with a canary deployment. This method allows for early detection of issues before a full-scale rollout.
Monitoring for both sensor and system performance is being improved, with feedback collected during Rapid Response Content deployment to guide a phased rollout. Customers will also be given greater control over the delivery of these updates, allowing for granular selection of when and where updates are deployed. Additionally, content update details will be provided via release notes, which customers can subscribe to for timely information.
Ensuring Third-Party Validation
To further bolster confidence in the system, multiple independent third-party security code reviews will be conducted. These reviews will provide an unbiased assessment of the security measures in place. Furthermore, independent reviews of end-to-end quality processes from development through deployment will be carried out to ensure comprehensive oversight.
In addition to this preliminary post-incident review, CrowdStrike is committed to publicly releasing the full Root Cause Analysis once the investigation is complete. This transparency aims to foster trust and demonstrate a commitment to continuous improvement in software resiliency and testing.
