other related equipment, as well as managing and using the radio frequency spectrum, address space and numbering, as the naturally limited public goods, are of interest for the Republic of Croatia. The legal, regulatory and technical provisions adopted at the EU level, related to data protection, privacy and legitimate interests of legal entities in the area of electronic communications, require continued harmonisation in order to make sure that there will be no impediments to promoting and developing new electronic communication networks and services among the EU Member States. The basic objectives of the Republic of Croatia related to cyber security in the area of public electronic communications are: Objective A.1 Inspection of technical and organizational measures taken by operators to ensure the security of their networks and services, and directing the operators of public communication networks and/or services with the aim of ensuring a high level of security and availability of public communication networks and services. It is necessary to cover the various requirements imposed on the operators, from quality and availability of networks and services, through requirements regarding data protection, requirements for ensuring adequate attention in implementing security measures based on the appropriate international standards, requirements for implementing legal obligations of secret surveillance of electronic communication networks and services, to the necessity of developing and constantly improving security cooperation and information exchange with the bodies responsible for computer security incidents in the area of public electronic communications and criminal prosecution authorities. Objective A.2 Direct technical coordination between the national regulatory authority for the area of electronic communications and national and international authorities responsible for the area of information security. It is necessary to establish and continuously develop inter-sectoral collaboration of national regulatory authorities and authorities responsible for the area of information security and data protection policy, and establish coordination and exchange of experiences in cooperation and requirements arising from the international framework. Objective A.3 Encouraging the providers of public communication networks and/or services to use the national centre for Internet exchange in providing services to users in Croatia. The non-profit service Croatian Internet eXchange (CIX) provides mutual exchange of internet traffic among the users of different service operators using the shortest communication path within the national system of public electronic communications. This kind of Internet exchange represents a security requirement for operators providing services to state authorities, but it also calls for efficient and economic national-level connecting of all the other economic sector users and citizens of the Republic of Croatia. 10 of 31
