Computer network security

Module title:

Computer network security

Module overview:

The objectives of this module is for students to understand network security as a characteristic of a network and to learn how to implement security principles, mechanisms, and technologies used in modern networks.

Students learn to implement:
• DoS protection in computer network
• IPsec mechanisms to secure tunneling between remote sites
• a Next-generation firewall and configure it to protect the network
• application control and malicious code protection in the network

This module is important because it introduces students to complex security technologies and their implementation in complex network environments. After successfully passing this module students will be able to implement complex secure network infrastructure with remote locations (e.g. multiple campus networks connected over the internet)
