The contemporary penetration of information systems into all sectors of human activity is also a cause of the increase in the number of cyber-attacks. This trend also has also hit critical informationinfrastructures (further only – CII). Their failure could have a great impact on the population – and the state itself. Nowadays, networking between industrial systems is increasing rapidly.
That is why there is an ever-growing number, sophistication and complexity of cyber-attacks on CIIs. This trend is thus leading to the formation of a new cyber battlefield, where private and state players – each promote their own interests by means of sophisticated cyber weapons.
