Abstract

Abstract — A Local Area Network (LAN) is usually privately owned and links the devices in a single office, building, or campus. Currently, LAN has been widely used in the different fields. Depending on the requirements of an organization and the kinds of technology used, a LAN can be extended throughout a company or institutions and include voice, images, texts, and videos peripherals. Security in a local area network comprises of the provisions and policies adopted by a network administrator to monitor and prevent unauthorized access, modification, misuse or denial of a computer network and network accessible resources. Network security covers a variety of computer networks, both private and public, that are utilized in everyday job conducting transactions and communications among government agencies, individuals and business. Network can be private, such as within an institutions and company. The most common and simple way of protecting a network resource on server is by assigning a unique name and corresponding password for clients to access a server to get information. In this paper, we propose a new approach to improve server security in a local area network by checking MAC address when the clients want to access the server. The system has been designed to deal with low security level on the server. To do that different testing has been implemented on the system to identify the improving security on the server. The experiments result show that the new security method is efficiency and accuracy in improving the security on the server and the method can effectively deal with clients to access the server in a local area network.
