Key Lessons From CrowdStrike’s Digital Outage

Friday, July 19, 2024, marked a date to remember for the digital collapse that paralyzed millions of users worldwide. A faulty update from the cybersecurity platform CrowdStrike led to a widespread blackout on Microsoft Azure, impacting millions of devices worldwide. This incident not only revealed the fragility of interconnected systems but also highlighted the crucial need for companies to be prepared for unexpected crises.

For many businesses, this event was a wake-up call, revealing gaps in their crisis response strategies. Beyond the immediate fallout, the situation presented a valuable opportunity to learn and enhance cybersecurity incident recovery strategies.

Chief information security officers (CISOs) have traditionally focused on threat detection and prevention, employing advanced technologies like XDR solutions and next-generation firewalls. However, the CrowdStrike-induced blackout served as a stark reminder of the importance of prioritizing recovery strategies as well.

Rethinking Recovery Strategies

In the aftermath of July's digital blackout, organizations began to reevaluate their recovery strategies. A key takeaway was the need for regular drills and testing of contingency plans. Simply having documented protocols is insufficient; they must be rigorously followed when it matters most. Companies must ensure that their employees are trained and ready to act according to these plans during a crisis.

Another critical lesson involved reviewing agreements with hardware and software providers. Relying solely on a single provider poses significant risks. It is essential to diversify and have multiple backup options to support the company in case of a failure. The principle of not putting “all your eggs” in one basket is especially pertinent in the context of disaster recovery.

Similarly, companies are beginning to more strictly evaluate their suppliers, particularly those who are part of the IT supply chain. Cybersecurity incidents in recent years have demonstrated that the supply chain is one of the main attack vectors. Therefore, it is essential for organizations to regularly verify and audit their suppliers to ensure they meet the necessary security controls.

It is also crucial to classify suppliers based on their criticality and apply appropriate security measures accordingly. Critical suppliers must comply with all security controls, while less critical ones might be subject to more relaxed requirements. This segmentation enables more efficient and targeted management of security resources.

Commitment and Communication

Senior management, including the board of directors and C-level executives, play a vital role in risk management and the implementation of recovery plans. Without strong commitment from top leadership, making substantial progress in incident preparedness and recovery is challenging. It is imperative that these leaders are aware of the risks and support the necessary measures to mitigate them.

Communication during a crisis is another aspect that is often overlooked. The CrowdStrike incident demonstrated the importance of managing both internal and external communication effectively. Clients and suppliers must be informed clearly and promptly to maintain trust and prevent panic. Well-managed communication can mean the difference between a controlled crisis and a significant loss of reputation.

Additionally, the experience with the CrowdStrike incident underscores the importance of learning from past mistakes. Companies must review previous incidents and assess their responses. This analysis helps establish a baseline of knowledge, which is crucial for dealing with future events. Continuous improvement through learning from experience is key to better preparedness for unforeseen challenges.

In Mexico, as in many other countries, disaster recovery in cybersecurity has not received sufficient attention. While there have been investments in detecting and protecting against incidents over the years, recovery efforts have lagged. This global event should serve as a reminder of the urgent need to develop and strengthen recovery plans.

The cybersecurity incident triggered by CrowdStrike has undoubtedly provided valuable lessons that Minsait considers fundamental. Beyond threat detection and protection, it emphasizes the importance of being prepared to recover quickly when security incidents materialize.

From Minsait's perspective, diversification and supplier control, rigorous supply chain evaluations, effective and timely communication, and robust support from senior management are essential pillars of an effective recovery strategy. Ultimately, the ability to recover and resume operations swiftly after an interruption, regardless of the cause, is what truly matters.
