How to Minimize Software Update Risks: Lessons from the CrowdStrike Incident

In: All, Article

The recent CrowdStrike incident, caused by a faulty update, affected over 8.5 million computers worldwide, underscoring the critical need for robust software update processes. While no software is entirely free from bugs, a well-structured update release system can significantly reduce the risk of large-scale failures.

Multi-Level Testing for Minimizing Software Update Risks

Effective update management starts with multi-level testing. At our company, updates undergo rigorous checks, including testing for false positives against a vast database of legitimate files and behaviors. This ensures that new detection rules or functionality changes do not mistakenly classify safe software as harmful.

Updates are also tested on virtual machines with various configurations to simulate real-world scenarios, ensuring the update doesn’t negatively impact system performance or stability. We even test compatibility with industrial software like SCADA systems to prevent disruptions in critical operations.

Phased Update Releases: A Proactive Approach

To further minimize risks, updates are rolled out in phases. Initially, updates are tested internally, then gradually released to a small group of users. This phased approach allows us to catch any unforeseen issues before they reach a larger audience.

Automatic Anomaly Monitoring

Even with thorough testing, issues can still arise. That’s why we monitor updates in real-time using anonymized data. If a problem is detected, the update distribution is halted immediately, limiting the impact to a small number of users.

Client-Side Testing: Adding an Extra Layer of Security

We also provide tools for clients to test updates in isolated environments before deploying them company-wide. This extra layer of testing helps ensure updates won’t disrupt business operations.

Continuous Improvement

Our commitment to minimizing update risks involves ongoing analysis of any issues, proactive risk assessment, and systematic improvements to our processes. This multi-level system has proven effective, preventing major incidents for over a decade.

By sharing our best practices, we hope to contribute to a more resilient cybersecurity industry. Open collaboration is essential for building stronger defenses against cyber threats.
