ENSURING THE SECURITY AND ADAPTATION OF CRITICAL INFRASTRUKTURE CONSIDERING THE PRINCIPL OF PROBABILITY ADEQUACY

Problem statement. Due to military aggression, Ukraine faces existential threats. Lives are lost every day, and critical infrastructure (hereinafter CI), along with civilian and military facilities, suffer significant damage. The adversary’s unconventional hostile actions clearly reflect an attempt to force our country into territorial and political concessions by destructively impacting the resilience of national security system elements. Therefore, ensuring Ukraine’s security and defense is the foremost priority today, and maintaining the country’s economic stability (resilience) amid war is as essential as protecting the lives and health of citizens. It is known that the security and economic stability (resilience) of a country are impossible without the stable operation of CI. According to clause 23, Article 1 of the Law of Ukraine “On Critical Infrastructure” [1882-IX], “critical infrastructure resilience” refers to a state in which CI maintains its ability to function in normal mode, adapt to constantly changing conditions, withstand and quickly recover from any type of threat. In accordance with clause 1, Article 15 of the Law of Ukraine “On Critical Infrastructure” [1882-IX], the protection and resilience of CI are provided in the following modes of operation: normal mode; readiness and threat prevention mode; crisis response mode; and recovery mode to restore normal functioning, with CI operating in normal mode according to its design purpose. The absence of an adaptation mode in this list, along with the lack of resilience measures for CI in these modes, complicates the security process, which presents a problem. The purpose of the article – is to substantiate the necessity of synthesizing and introducing the concept of “critical infrastructure adaptation” into the provisions of the Law [1] and other interrelated regulatory acts. Conclusions. The necessity of synthesizing and introducing the concept of 'critical infrastructure adaptation' into the provisions of the Law [1] and other interrelated regulatory acts has been substantiated. A new formulation of the concept of “critical infrastructure adaptation” is proposed for the first time.
