A Secured Enterprise Network Using Hierarchical Network Model and Artificial Neural Network: A Case Study of Faculty of Engineering, Rivers State University

This paper presents specifications and design of a secure, scalable, available, and manageable hierarchical network for Faculty of Engineering, Rivers State University, Port Harcourt, Nigeria. The developed Network prototype was designed to include the various
services that consist of an enterprise network as a unit. In addition, Artificial Neural Network technique was used to develop a unique encryption key as an additional security for the Faculty database. Furthermore, the block diagram, physical and logical network topology of the Faculty of Engineering, were successfully designed. The specifications from the design was used to configure network devices, servers and security features. The outcome of the design was estimated to reduced network device load and the time to identify and resolve network issues by a ratio of 1:8. Moreover, the outcome of the design also enhanced rapid connectivity, and the inclusion
of new devices did not affect the transfer of packets. Finally. The configuration and specifications used for study would serve as a prototype that can be replicated and deployed to other Faculties or Universities
