IT security is the protection of IT systems - from individual files to computers, networks and cloud services through to data centers - against damage and threats. Cyber security extends IT security to the entire cyberspace. IT security is a sub-aspect of information security. While IT security refers to the protection of technical systems, information security is generally concerned with the protection of information. The aim of data security is to ensure the confidentiality, integrity and availability of data. In contrast to data protection, it is not limited to personal data, but extends to all data.
