ABSTRACT
Once a Soviet Union republic, Ukraine gained its independence after the Soviet Union collapsed in 1991. To help illustrate Ukrainian–Russian hybrid warfare, there was one particular incident that deeply shocked and awakened the international community. The first challenge that Ukraine faced in the Russian hybrid war was the inconsistency of Soviet and NATO cybersecurity standards. After the Crimean Peninsula occupation, Russia moved to gain control over Ukrainian eastern and southern territories, first by means of Russian inspired protests led by Russian special forces officers that soon turned into open military aggression by the Russian army with the use of hardware military equipment. The hybrid war with Russia prompted the Ukrainian government to pass several informational defense laws and Presidential Mandates that set up a road map for reformation of the Ukrainian informational defense systems to adequately meet contemporary cybersecurity challenges.
