Rebuild Cascades: When Protection Mechanisms Become the Primary Risk Vector

Abstract

The paper discusses the ironic situation where safety devices intended to make a system more resilient in cybersecurity, critical infrastructure, financial, and healthcare sectors might actually lead to an increase in hazards at the system level. As systems become more interconnected and complex, safety features such as automated failover, redundancy controls, intrusion detections, and regulatory safeguards can inadvertently disguise interdependencies, generate feedback loops, and escalate failures. In the paper, the authors present a thorough literature review, comparative case studies across different domains, the development of a conceptual framework, and computer simulations that collectively reveal the flashing signs of a protective mechanism starting a "rebuild cascade" scenario, where the system post-recovery or containment steps further deteriorate the state of the system. Five major issues: very tightly connected dependencies, differently aligned thresholds, over-automation, delayed human engagement, and unclear control logics have been identified as the most significant risk concerns. The article suggests that safety devices might destabilize the system if they are: providing the fastest solution without consideration of the whole system/prioritizing rapid response without holistic system awareness, working in isolation without adaptive coordination, or strengthening rigid and inflexible dependencies. The author disagrees, and proves his point through research, that while in highly specialized and interdependent environments at high pace, resilience layers do not necessarily reduce risk; overprotection makes a system more fragile. Transparency, adaptability, and cross-system scaling, according to a novel model that connects protective measures with failure causes, are the most critical concepts in designing robust systems that are truly resilient.
