Systems Disruption: Exploiting Interconnected Vulnerabilities Continuing with John Robb's "Brave New War" which introduced a prescient concept that has become increasingly relevant in our interconnected world: systems disruption. Robb argued that in modern conflicts, targeting critical infrastructure could cause widespread chaos and undermine a state's ability to maintain control. This strategy, focusing on exploiting vulnerabilities in complex systems rather than engaging in direct combat, has proven remarkably accurate in predicting the nature of modern threats.
The core of Robb's insight lies in recognizing the inherent fragility of our interconnected systems. As societies have become more technologically advanced, they've also become more dependent on complex networks of infrastructure from power grids and water supplies to financial systems and communication networks. While these interconnected systems offer tremendous benefits in terms of efficiency and capability, they also present a significant vulnerability. A well-placed attack (or bad update in the case of Crowdstrike) on a critical node can have cascading effects, causing disruptions far beyond the initial point of impact. Robb's concept goes beyond traditional notions of sabotage or infrastructure attacks. He recognized that in a world of complex, interdependent systems, relatively small actions could have disproportionately large effects. This asymmetry is particularly appealing to non-state actors or smaller powers who lack the resources for conventional military confrontations. By targeting key vulnerabilities in critical systems, these actors can potentially cause widespread disruption and chaos without the need for large-scale military operations. The psychological aspect of systems disruption is another key element of Robb's analysis. He understood that beyond the immediate physical or economic impacts, successful attacks on critical infrastructure could erode public confidence in the state's ability to provide basic services and security. This loss of confidence can be as damaging as the physical disruption itself, potentially leading to social unrest or political instability. Robb's foresight in identifying the potential for systems disruption has been validated repeatedly in recent years. Cyber attacks on power grids, ransomware targeting healthcare systems, and disruptions to financial networks have all demonstrated the vulnerability of our interconnected world, the Colonial Pipeline ransomware incident is a good example of this. These incidents have shown that Robb's concept of systems disruption is not just a theoretical construct, but a real and present danger in modern conflicts. As our reliance on technology continues to grow, so too does the potential for systems disruption. The rise of the Internet of Things, the increasing digitization of critical infrastructure, and the growing sophistication of cyber weapons all point to a future where the risks of systems disruption are likely to increase rather than diminish. In response to these threats, Robb emphasized the need for resilience in our critical systems. This means not just hardening defenses, but also building redundancy and adaptability into our infrastructure. The goal is to create systems that can withstand attacks or disruptions and quickly recover, rather than cascading into widespread failure. The CrowdStrike incident of July 19, 2024 serves as a good illustration of the risks inherent in centralized systems, particularly as it relates to cybersecurity. CrowdStrike, a major player in the cybersecurity industry, experienced a critical software update failure that cascaded into a widespread outage affecting millions of devices across various sectors. The incident began with a seemingly routine software update to CrowdStrike's Falcon platform. However, a misconfiguration in the update caused the security software to malfunction, effectively disabling endpoint protection for a vast number of clients simultaneously. This single point of failure in a centralized system rapidly escalated into a crisis affecting financial institutions, healthcare providers, energy companies, and government agencies. I experienced this first hand with my work laptop and later that morning trying to take the CCSP at a testing center as all the computers were BSOD. Banks reported disruptions in transaction processing systems, hospitals faced interruptions in accessing patient records, and several power plants had to switch to manual operations due to concerns about compromised industrial control systems. The ripple effects of this outage highlighted how deeply embedded CrowdStrike's services had become in critical infrastructure across multiple industries. What makes this incident particularly noteworthy is that it wasn't the result of a malicious attack, but rather an internal error, however this is what a crippling cyber attack could look like. This underscores a key vulnerability of centralized systems even without external threats, they can still fail catastrophically. The concentration of so many critical services under one provider created a single point of failure that, when compromised, had far-reaching consequences. The CrowdStrike outage should serve as a wake-up call about the dangers of over-reliance on centralized cybersecurity solutions and systems. It demonstrated how the very systems designed to protect against disruption can themselves become vectors for widespread disruption when they fail. This incident reinforces the need for diversity and redundancy in critical systems, echoing John Robb's warnings about the vulnerabilities created by our interconnected, centralized infrastructure.
