Introduction to networks and network security A network consists of a system of interconnected computers. Networks let people reach to geographically distant resources without being physically present. It is also used to send data back and forth to be connected. Networks can be of varied sizes but the purpose of network security is to protect them from unauthorised access and misuse. A Network Security Function (NSF) is a function that makes sure of the integrity, confidentiality and availability of network communications, to detect unnecessary network activity, or to stop or at least reduce the efficiencies of unusual activities. NSF’s are offered and consumed in rapidly varied environments. Users can utilise network security services given by NSF hosted by one or more providers that may be their own enterprise, service providers, or a combination of both.
