Surprising Insights Gained From the CrowdStrike Event

The recent global IT issues caused by a defect in a content update for CrowdStrike’s Falcon sensor have sent shockwaves through the business world, prompting organizations to implement their business continuity plans and focus on recovery efforts. The incident, which affected 8.5 million PCs across various sectors and organizational sizes, served as a wake-up call for all businesses, regardless of their size or industry.

Even non-CrowdStrike customers felt the impact, with disrupted flights, halted transactions at gas stations and grocery stores, and delays in critical services like police and fire dispatch. The scale of the disruption highlighted the importance of preparedness and response capabilities in the face of cyberattacks.

One of the key takeaways from this event is the importance of detection in responding to cyber incidents. The clear and immediate nature of the CrowdStrike event served as a reminder of the critical role of quick detection in mitigating the impact of cyber threats. Organizations need to assess their ability to detect outages promptly and identify root causes to effectively respond to ransomware attacks.

The response phase of the incident also shed light on the challenges many organizations face when trying to recover from cyber incidents. Incomplete asset inventories, difficulties in prioritizing recovery activities, and obstacles in scaling operations quickly were common issues encountered during the response to the CrowdStrike event. These challenges mirror those organizations face during ransomware incidents, emphasizing the need for robust response plans and asset management.

Business continuity planning emerged as a crucial area for improvement, as organizations struggled to restore mission-critical functions during the incident. Many organizations were unable to differentiate between business continuity plans and disaster recovery plans, leading to difficulties in executing critical functions. The importance of conducting a business impact analysis and integrating the results into comprehensive BCPs cannot be overstated in preparing for ransomware incidents.

The event also highlighted the risks associated with supply chain and vendor relationships in the face of cyber disruptions. The downtime experienced by Kronos due to a ransomware event serves as a stark reminder of the importance of supply chain diversification and contingency planning. Organizations need to consider and plan for cyber incidents affecting their supply chains to ensure business continuity.

As organizations reflect on the lessons learned from the CrowdStrike incident, there is a unique opportunity to improve resilience and preparedness for future cyber threats. Whether directly affected by the incident or indirectly impacted through supply chain partners, organizations need to focus on enhancing their response capabilities, improving asset management, and prioritizing business continuity planning. The key takeaway from this event is the need for continuous improvement in cybersecurity practices to mitigate the impact of cyber incidents in the future.
