Cybersecurity involves protecting computers, servers, mobile devices, electronic systems, networks and data from malicious attacks. It is also called computer security or information systems security.

Cyber defense brings together all the physical and virtual means put in place by a country as part of computer warfare.

Placed under the direct authority of the Chief of Staff of the Armed Forces, the commandement de la cyberdéfense (COMCYBER) is an operational command, which brings together all of the ministry's cyberdefense forces under a joint authority. Its mission is the defense of information systems, as well as the design, planning and conduct of military operations in cyberspace.
