According to Wikipedia, Network security consists of the provisions and policies adopted by a network administrator to prevent and monitor unauthorized access, misuse, modification, or denial of a computer network and network-accessible resources. The administrators of the network have the sole rights to assign access privileges to various users of the network so that unwanted people cannot use a private network.
