You learn the new Intrusion tolerance paradigm with proxy-based multipath routing for DDoS defense. By developing and deploying such a new security mechanism, you can improve performance and reliability of the system at the same time and it does not have to be just an overhead. By the end of this course, you should be able to analyze new DDoS malware, collect forensic evidences, deploy firewall features to reduce the impact of DDoS on your system and develop strategies for dealing with future DDoS attacks.
For the pre-requisites, we recommend the learners take the Design and Analyze Secure Networked Systems course to learn the basic security concepts and principles and take the Secure Networked System with Firewall and IDS courses to learn the basic firewall and IDS systems.
