The Dangers of Overlooking Cybersecurity Basics

In the month of July, a widespread technological glitch caused chaos as 8 million Windows devices globally went offline due to a flawed software update released by CrowdStrike. This update, which contained a faulty content validator, had severe consequences across various sectors. Hospitals faced difficulties accessing essential patient records, disrupting crucial patient care services. Airlines were compelled to delay or cancel thousands of flights, causing inconvenience to countless travelers. Moreover, some payment platforms became unavailable, leading to delays in payments for many individuals. The Emergency Alert System in the United States also experienced disruptions, affecting 911 services in multiple states.

The root cause of this incident was attributed to an inadvertent systems failure aggravated by substandard patch management practices that violated third-party risk management policies and procedures. CrowdStrike’s quality control testing failed to identify the software bug prior to deployment, and there was no rollback mechanism in place to revert the update after installation. This scenario underscored the repercussions of neglecting basic IT protocols, emphasizing the critical importance of adhering to established guidelines to prevent such mishaps.

According to cybersecurity consultant Eric O’Neill, cloud-based endpoint detection and response (EDR) security tools like CrowdStrike’s solution rely on real-time intelligence processing from the cloud. He highlighted the significance of effective patch management and recommended a phased rollout approach for implementing patches to identify and resolve issues progressively. O’Neill emphasized the need for organizations to conduct thorough testing of patches before integrating them into their systems to mitigate potential risks.

As the affected customers of CrowdStrike predominantly opted for automatic security update installations rather than staged rollouts, the incident prompted a reevaluation of patch deployment practices. O’Neill anticipated substantial alterations in how organizations execute patch installations in the future to prevent similar disruptions. He deemed the decision to forego testing understandable given the absence of previous patch-related anomalies but emphasized the imperative of implementing robust testing protocols moving forward.

Consulting CISO John Young likened the impact of this unintentional outage to past cyberattacks on SolarWinds and Kaseya, albeit without malicious intent. He highlighted the significance of conducting thorough business risk and interruption analyses, emphasizing the importance of diversifying operational risks across multiple operating systems to reduce vulnerabilities. Young suggested deploying hot backup systems with varied operating systems to ensure continued service delivery in the event of disruptions, providing a buffer for organizations to recover from potential system failures.

The repercussions of the CrowdStrike outage also raised considerations regarding cyber insurance coverage. While the event was not a cyberattack, certain cyber insurance policies might encompass coverage for dependent systems failures unrelated to malicious activity. David Anderson, Vice President of Cyber Liability at Woodruff Sawyer, emphasized the importance of reviewing insurance policies to determine coverage for system failures and highlighted the distinctions between system failure events and malicious attacks within insurance coverage frameworks. The incident prompted organizations to reassess their existing insurance policies to ensure comprehensive coverage for unforeseen events.

In conclusion, the CrowdStrike outage served as a wake-up call for organizations to prioritize robust IT management practices, emphasizing the importance of proactive risk mitigation strategies and meticulous patch deployment procedures. The incident underscored the critical need for comprehensive cybersecurity measures and thorough planning to prevent similar disruptions in the future.
