Vulnerability and Protection of Critical Infrastructures

TL;DR

This paper presents a method to identify critical components in infrastructure networks, focusing on nodes vital for network functionality, which aids in protection strategies and network planning.

Contribution

It introduces a novel approach to detect critical nodes in infrastructure networks, emphasizing their importance over simply highly connected nodes.

Findings

The method effectively identifies nodes crucial for network integrity.

It can be used to improve infrastructure protection strategies.

The approach assists in planning network expansions.

Abstract

Critical infrastructure networks are a key ingredient of modern society. We discuss a general method to spot the critical components of a critical infrastructure network, i.e. the nodes and the links fundamental to the perfect functioning of the network. Such nodes, and not the most connected ones, are the targets to protect from terrorist attacks. The method, used as an improvement analysis, can also help to better shape a planned expansion of the network.
