The article presents the current issues and latest trends of the legal and administrative aspects of ensuring public security in the field of state border protection. Firstly, the research reveals aspects of the public security threats in the sphere of national border security. Secondly, discusses the administrative legal regimes of the state border and frontier. Further discussion pertains to the functions and strategic goals of the State Border Guard Service, and the activity-related problems are elaborated. Finally, attention is devoted to one of the significant priorities, aiming at ensuring public security in this field – the EU external border control and protection. The authors applied general scientific methods of studying objective reality, peculiar to legal sciences: systematic document analysis, meta-analysis, structural-functional analysis, teleological, comparative, critical approach, generalisation and prediction. As a result in this research is emphasised the importance of decentralisation in ensuring public security at the level of the state territorial borders; the main guidelines of modernisation in this field are presented.
