This article considers the issue of annexation of the Ukrainian Crimea peninsular territory by the Russian Federation and further deployment of the secessionist movement in the southeastern regions of Ukraine that subsequently developed into a military conflict in the east of Ukraine. The research analysed the directions and character of the cooperation between the Armed Forces of Ukraine and the Alliance military units. The level of practical interaction within the framework of existing NATO-Ukraine bilateral partnership programs, including military trainings, was also identified. The chronology of transformation of organizational forms of Ukrainian army’s presence in the east of Ukraine from the Anti-Terrorist Operation to the Joint Forces Operation and the role of NATO in this process were also considered. The elements of the North Atlantic Alliance’s influence on the reform of the Ukrainian army were identified directly following the requirements and standards defined by the Organization. The role of NATO’s Liaison Office, located in Kyiv, Ukraine, and the Center for Security and Information Processing was outlined. Particular attention was paid to the issue of counteracting cybercrimes and protecting the state’s information systems from external influences. In particular, reference was made to the protection of the state’s critical infrastructure elements (nuclear power plants, strategic state-owned enterprises, etc.), including electronic registers of citizens e-lists and the state’s banking system databases. The activities of the NATO Cybercrime Operations Centers and the establishment of similar institutions in Ukraine were also researched. The maritime component of cooperation between Ukraine and the North Atlantic Treaty Organization was analysed, taking into account the aggravation of the situation in Azov-Black Sea region during 2018, associated with the passage of Ukrainian warships of the Azov Fleet of the Naval Forces of Ukraine through the Kerch Strait which is under the control of the occupying troops of the Armed Forces of the Russian Federation. As a result, so-called border conflicts were caused leading to the capture of Ukrainian warships and sailors by Russians in November 2018.
