Course introduction
The purpose of this course is to give an understanding of the issues involved in networks and computer security, for prevention and detection of security problems.

Expected learning outcome
At the end of the course the student is expected to be able to:

• Explain basic network concepts and the structure of the internet.
• Implement a layered network protocol similar to TCP/IP
• Explain functionality and interfaces for the application layer of the TCP/IP model and the functionality of DNS
• Explain functionality and interfaces for the transport layer of the TCP/IP model and the difference between UDP and TCP
• Explain functionality and interfaces for the network layer of the TCP/IP model and explain basic routing algorithms, and routing in the internet.
• Explain functionality and interfaces for the link layer of the TCP/IP model, including error detection and correction.
• Explain characteristic differences between wireless and non-wireless networks.
• Use a packet-sniffer to analyze network trafic.
• Explain the concepts behind and applications of both symmetric and public key crypography.
• Explain concepts behind and implementation of the following:
• Key distribution and user authentication.
• Transport level security.
• IpSec and VPN
• Wireless network security.
• Electronic mail security.
• The problems causing recent security holes in software in contact with networks.
• Explain techniques used to detect and prevent intruders and malicious software.
• Describe different types of firewalls, and their strengths and weaknesses.
