Cybersecurity refers generally to an entity’s ability to ward off cyberthreats and prevent data loss from a holistic point of view—that is, how well networks, applications, users, and endpoints protected. Network security is an element of cybersecurity that focuses mainly on how well an entity’s network infrastructure is protected from cyberthreats, data loss, and the like. Cybersecurity is a discipline and a goal to be achieved by an entity, and network security is one component of such a discipline or goal.
