Security Architecture for Thin Client Network
Client-server is a modern shift in computing paradigm that different from traditional (pc-server) computing in the sense that data resides remotely on the server, this makes centralized management data possible. Client-server has an edge over traditional computing model in the areas of functionality, performance, and reliability. Client computing has become cost effective and centrally managed network. It reduces total cost of ownership (TCO) to a great extent improved services and lower power usage in comparison to pc-server computing model. However, there are security challenges facing client-server computing such as inability for security solution to identify user based on its static type of IP address. This paper presents Dynamic Host Control Protocol (DHCP) as a remedy to challenges associated with dynamic assignment of IP address. These enable to detect spoofing of MAC address with login parameters that does not match information in the server, when an attacker tries to “break in”, using inconsistent parameters, the MAC address in which an IP is assigned will mismatch and as a result there would be an IP address conflict detected by the administrator. The design thin-client network framework help to overcome the identified security challenges of client-server network.
