Aims of Module

To provide the student with the ability to understand and manage the security and client-server (e.g. web-server) aspects of computer networks with Internet access.

Learning Outcomes for Module

On completion of this module, students are expected to be able to:

1.	Evaluate the security implications of computer networks and develop a security policy to protect systems and data.
2.	Implement systems to protect network users from computer viruses and hostile applications.
3.	Identify suitable file and data encryption mechanisms to prevent eavesdropping and protect privacy.
4.	Define and implement counter measures to combat against unauthorised network access.

Indicative Module Content

Security policy objectives: availability, integrity, privacy, authenticity; assessing exposure, countermeasures. Threat reduction analysis. Methods of attack: Eavesdropping, spoofing, Trojan horses, viruses, denial of service. Protection mechanisms: DES and Public Key encryption, Secure Socket layer (SSL) for web transactions, digital signatures. Firewall configuration and the de-militarised zone. Virtual Private Networks (VPN). Access Control Lists.
