Currently many states consider military confrontation as a resistance happening not only within four standard domains: earth, naval, air and near-earth space, but also in informational and cyber space. As a result, security of material and informational military objects (as parts of critically important state infrastructure) and their safety from threats, realized through application of special informational technologies for malware usage and destruction, become one of the main problems of the present. At the same time the biggest anxiety is caused by informational security of nuclear weapon control and administration systems.
