This course focuses on protective systems used in securing internal and external networks. It covers a range of security technologies such as firewalls, NAT, IDS, honeypot, and a host of other security mechanisms for providing security at different TCP/IP layers. It examines in detail the widely used protocols including SSL, IPSec, and DNSSEC as well as covers topics related to securing the infrastructure including wireless security (IEEE 802.11). This course also explores the current research and developments in the area of network defence and countermeasures. The research aspect is mainly covered in individual seminars, which are based on recent research articles published at top-notch venues. There is a group report, which typically extends the presented articles. Finally, there is a final exam based on lectures and seminars.
The skills developed in this course are particularly useful for those wishing to have a career involving cybersecurity. The course project will be helpful for those who are planning to develop expertise in writing research reports.
