Security Geometry: Measuring System Resilience

This article examines the concept of security geometry as a key tool for measuring the resilience of critical infrastructure systems. The author points to the need to understand the network architecture of connections rather than simply pooling resources. Using graph theory and game theory, the text demonstrates how to mathematically model interactions between systems and threats. Legal frameworks such as the CER, NIS2, and DORA directives are referenced in the context of contemporary geopolitical challenges. It emphasizes that the security of a modern state depends on the invisible geometry of connections, which determines the ability to survive conditions of extreme stress, failure, or sabotage. This interdisciplinary perspective combines engineering, economics, and law in the service of the reliability of essential services.
