4) Area - information security of the Republic of Serbia: - Information security system relevant for national security defined; - CERTs for independent ICT system operators established. The development of information security gained momentum with the passing of the Law on Information Security, which introduced, first and foremost, the main institutional prerequisites for the development of this field, as well as other prerequisites for a country to establish sound information security arrangements. A key achievement of Action Plan implementation is certainly the establishment of an incident reporting and response data exchange system, as a mechanism to monitor the state of play in this field. As awareness raising and improved knowledge of information security, coupled with capacity building of the relevant staff, were identified as paramount, numerous activities have taken place (including seminars, conferences, trainings and panels) to raise awareness of incident risks and incident responses. Major progress has been achieved with regard to information security of children through the operation of the National Contact Centre for Online Safety for Children. Implementation of activities under the Action Plan marked the beginning of efforts to build the capacities of ICT systems of special importance, although it should be noted that there is much room for improvement in this regard, which will require investment in infrastructure, staff capacity building and improving the level of knowledge in this field. Based on the implementation of these Strategies in recent years, the activities and measures foreseen therein have been identified as appropriate and it is therefore recommended that the current Strategy build on them and continue with the same efforts towards achieving the stated objectives. 1.3 USAGE OF INFORMATION AND COMMUNICATION TECHNOLOGIES IN THE REPUBLIC OF SERBIA Details of the use of ICT in the Republic of Serbia, as the fundamental indicators of information society development, are provided in the publication of the Statistical Office of the Republic of Serbia entitled Usage of Information and Communication Technologies in Serbia, 2020. 1.3.1 Computer Use Computer use by households – Based on the main findings of this survey, 74.3% of households in the Republic of Serbia own a computer, which is an increase of 1.2% relative to 2019 and 2.2% relative to 2018.
