Interpretation of Key Terms for the Purposes of the Concept Cyber Security in General is the ability of any electronic communications network, electronic information and/or control system to resist, at a certain reliability level, random events and/or damaging activities that may negatively influence the integrity, faithfulness, confidentiality and availability of the stored, processed and/or transmitted data and/or services provided by the network or by an information or control system and thereby to disrupt and/or negatively influence the operability of, without limitation, one of the sectors of critical infrastructure27 and/or one of the basic security areas of operation of the state. Cyber Security from a Process Viewpoint, at a state level, is the system of continuous and planned increase in political, legal, economic, security, defence and educational awareness that includes increasing the efficiency of the adopted and applied technical and organizational measures of risk management in cyber space in order to transform it into a trustworthy environment that will provide for safe operation of social and economic processes while ensuring an acceptable level of risks in cyber space28. Cyber space is a virtual space without borders, seen as a global interactive domain in an information environment that is characterised by the use of the electronic and electromagnetic spectre for the creation, storage, modification and exchange of data and use of services. Cyber space also means a combined phenomenon of global connection, de-centralized and continuously growing electronic information, communication and control systems, as well of the interconnection of social and economic processes in the form of data and information using these systems, including the data stored and/or processed therein. National Cyber Space of the Slovak Republic includes the parts of the above systems of cyber space that are located in the territory of the Slovak Republic as well as other systems of cyber space that contain data and information aimed at the Slovak Republic and/or influencing the Slovak Republic29. Information Environment means a set of individuals, organizations and systems that collect, process, spread, or work with information irrespective of whether the information is in physical form, in audio form, or in electronic form. Information Security means: a set and application of security measures and procedures30 serving in the framework of a specific information environment, to protect information from impairment/loss, or compromising (loss of confidentiality, integrity and other characteristics such as authenticity, trustworthiness, non-deniability and reliability) and to preserve the availability of information and the ability to work therewith in the scope of assigned authorizations. 27 Act no. 45/2011 Coll. on Critical Infrastructure as amended, states in Art.2(c) that “critical infrastructure” is a system divided into sectors and elements. The meaning of these components is defined in Art. 2(a) and 2(b) of the same Act. 28 The term cyber security should also be understood as dedicated mechanisms, defined policies, as well as processes tasked to protect systems and data from cyber threats and/or attacks. 29 The definition of the contents of this term is of substantial importance from the formal law aspect as the jurisdiction of the Slovak Republic cannot be applied in the framework of cross-border, i.e. global cyber space, it must be limited to a part thereof, i.e. to the National Cyber Space. 23 30 Security project according to the ISO 27000 standard.
