Synthesis of protection systems of automated control systems against destroying program influence
Informatization and automation of various industrial facilities (including facilities that create potential safety threats) has made functioning safety of such objects one of the most important issues of modern age. Informatization and automation cause emergence of new types of threats for information security directed to violation of functioning of production objects that create a potential threat of safety, which can be exposed to destructive information and technical influences. These factors in combination with the increasing level of society dependence on functioning stability of the objects, which create potential safety threat, demand a package of measures (including technical measures) to decrease the risk of violation or complete cessation of such objects’ functioning under information and technical influences. The article presents one of possible approaches to constructing rational (in the context of ensuring the demanded security level and minimum influence of protection system on a protected automated system) system of protection against destroying program influences as the main type of possible information and technical influences on automated control systems for crucial and potentially dangerous objects.
