Cyber security is concerned with making cyberspace safe from threats, namely cyber-threats. The notion of “cyber-threats” is rather vague and implies the malicious use of information and communication technologies (ICT) either as a target or as a tool by a wide range of malevolent actors. As commonly used, the term “cybersecurity” refers to three things:
A set of activities and other measures, technical and non-technical, intended to protect computers, computer networks, related hardware and devices software, and the information they contain and communicate, including software and data, as well as other elements of cyberspace, from all threats, including threats to the national security;
The degree of protection resulting from the application of these activities and measures;
The associated field of professional endeavour, including research and analysis, aimed at implementing and those activities and improving their quality.
Cybersecurity is thus more than just information security or data security, but is nevertheless closely related to those two fields, because information security lies at the heart of the matter.
