Act 181/2014 on cybersecurity came into force on the 1st of January 2015. The law aims at making the country more resilient against cyber threats and attacks on important ICT infrastructures. The system for ensuring cyber security consists of: security measures, reporting of cyber security incidents, preparation of countermeasures, reporting of contact details and monitoring activities of supervising authorities. Both the law and related regulation define critical information infrastructures and important information systems. Operators of such infrastructures and systems, who can be either government as well as private organisations, must now comply with sets of rules and obligations. The law also introduces the term of “state of cyber emergency”. The main control function will be performed by the Czech National Security Authority via Government CERT, which was established in 2011.
