Cyber-physical systems networking with TCP/IP: A security application approach

Abstract

This paper deals with an approach to security analysis of IP-based computer networks for cyber-physical applications. The method developed stems from a formal model of network topology with changing link states, and deploys bounded model checking of network security properties supported by SAT-based decision procedure. Its implementation consists of a set of tools that provide automatic analysis of router configurations, network topologies, and states with respect to checked properties.
