Current cyber security threats and challenges in critical infrastructures protection

Nowadays there is a significant effort focused on national critical infrastructures evaluation, simulations and threats analysis. In this paper current situation and challenges relating to cyber security of Critical Infrastructures (CI) are discussed. Presented study shows that cyber-related threats should be concerned as significantly contributing factors incorporated into strategic analysis of infrastructure disruptions, consequences evaluation, and assessment of systems dependencies. The major contribution of the paper is a novel consequence-oriented classification of cyber threats to ICS (Industrial Control Systems) systems and critical infrastructures (CI).
