Computer networks

In today’s world, computer network is important every organization either at any step. Security is the one of the most important issue in the area of computer network. Security is a protection against internal and external problems. In this paper, implementation of privilege level and access-control mechanism has been done which helps in making the network secure. Privilege level phenomenon is implemented on the network devices that are on layer 2 and layer 3, so that only the chief user of network has the right or power to make changes in the configuration and the chief user is responsible for select the access for the local user. The access-control mechanism is also implemented, which controls and maintains the access of all user in the respective network so that all services are under the control of network administrator. Every authorised user is able to use only those services for which the privilege has been given to user from the administrator end.
