History of networks dates back to the early 1970's and due to the emerging ding demand placed on networks by administrators and users, securing the network becomes a necessity. In this paper, the authors studied the various existing methods employed in securing private networks and came up with using radius server as a backbone to network security. A dedicated network was designed and the administrative and client networks on Virtual LAN (VLAN) basis configured. This ultimately authenticates a valid user and rejects an invalid user from gaining access into the network using the method of Authentication, Authorization and Accounting (AAA), while monitoring the valid user and keeping record of activities on the network.
