Computer Network and Network Security (FIN529)


FIN529 Computer Network and Network Security focuses on introducing computer networks andproviding an overview of network security. The first part of the course emphasises on giving anoverview of the different computer networks. It appraises the different network topology andvarious types of network protocols. The functionalities of each layer of the network protocols areexplained and elaborated. The network’s Quality of service (QoS) metrics essential to achieve goodnetwork performance are discussed in this course. The second part of the course is centered onnetwork security. It gives an introduction to cryptography and the key network security concepts.The course will expose a range of network security issues, risks and threats presence in the networks.Then, it moves on to discuss how these network security issues can be mitigated and managed.Overall, the course aims to provide an overview of computer network and network security, and thechallenges and opportunities related to computer network and network security.
