Cybersecurity belongs to the area of activity of state and supra-state actors, giving direction to national and international systems of law as components of national and supranational systems of political, economic, military cooperation, etc. Still, the state has a monopoly on the causality of lawmaking, which forms the basis of cyberspace use security activities. The state responds to national security needs by actively participating in the formation of the collective security order of the supranational level. The aim of this paper is to demonstrate the significance of the national Cybersecurity Strategy of the Republic of Poland for ensuring the safe use of cyberspace. The Strategy, while referring to the national order, is at the same time an implementation of supranational arrangements within the scopes adopted by the state authorities, which means that the Strategy is subjected to logical evaluation depending on the impact of cyber conditions or binding arrangements of the international environment. The text is based on two research methods: the doctrinal legal research method to analyse the applicable legal regulations governing the issues related to the strategic aspects of cybersecurity and the law theory method aimed at evaluating the strategic solutions in respect of security in cyberspace.
