Critical Infrastructure Attack Modeling

The development and connection of information and communication technologies with industrial control systems in the so-called critical infrastructure have contributed to the emergence of new complex threats. The critical infrastructure has become a target of sophisticated cyber attacks which exploit several, also unknown, vulnerabilities in one course of an attack. The paper proposes an attack modeling method enabling us to determine the vulnerabilities and riskful exposure of the systems. Organizational changes to ensure cyber defense of the critical infrastructure are also proposed.
