The creation of a coherent system to ensure the cybersecurity of the Republic of Poland was the purpose of the Act of the National Cyber Security System adopted by the Sejm of the Republic of Poland on the 5th of July 2018. It was the first attempt to create a comprehensive legal regulation, which assigned specific tasks and competences to its constituent entities and defined their responsibilities in order to enable effective operation in order to detect, prevent and minimise the effects of network incidents (such as, e.g. network attacks or failures) violating cybersecurity of the state and its citizens. In addition, the Act on the national cybersecurity system and the implementing regulations accompanying it have implemented the provisions of the Directive (EU) 2016/1148 of the European Parliament and the Council of the 6th July 2016 on measures for a high common level of security of network and information systems within the Union (the NIS Directive).
