Regulatory and legal support for international cooperation of the Security service of Ukraine during the fight against criminal offenses at critical infrastructure facilities

The article analyzes the regulatory and legal principles and practice of interaction between the Security Service of Ukraine and foreign states and international organizations in organizing counteraction to criminal offenses committed at critical infrastructure facilities. The relevance of the topic is due to the increasing transnational nature of threats, in particular cyberattacks, terrorist acts and other forms of criminal encroachments on the critical infrastructure of Ukraine. It is determined that effective counteraction to these threats is impossible without a developed system of international cooperation, which is based both on generally recognized principles of international law and on specialized mechanisms of law enforcement cooperation. Forms of international cooperation between the Security Service of Ukraine and foreign institutions are disclosed, in particular through the conclusion of international agreements, exchange of information, joint operations, participation in international exercises, creation of joint investigative groups, as well as coordination of efforts within the framework of the activities of such organizations as Interpol, Europol, Eurojust, NATO, OSCE, etc. The focus is on the analysis of the legal regulation of international cooperation - both in the context of domestic legislation (the Constitution of Ukraine, the laws of Ukraine «On National Security of Ukraine», «On Critical Infrastructure», «On the Security Service of Ukraine», the Criminal Procedure Code of Ukraine and other regulatory legal acts), and international treaties ratified by the Verkhovna Rada of Ukraine. Examples of the implementation of joint activities, in particular operations PowerOFF, Locked Shields, participation in the CISA, CCDCOE and I-FORCE projects, are demonstrated. It was established that the key task is to further improve the regulatory framework of international cooperation, harmonization with international standards, elimination of legal conflicts in cross-border access to digital evidence, increasing the interoperability of services and deepening trust between partners. It was stated that the SBU is a subject of the national critical infrastructure protection system, the security and defense sector, capable of effectively counteracting criminal offenses at critical infrastructure facilities, provided that there is effective regulatory and legal support for international cooperation.
