About the Course

In this MOOC, you will learn the history of DDoS attacks and analyze new Mirai IoT Malware and perform source code analysis. you will be provided with a brief overview of DDoS Defense techniques. You learn an Autonomous Anti-DDoS Network called A2D2 for small/medium size organizations to deal with DDoS attacks. A2D2 uses Linux Firewall Rate limiting and Class Based Queueing, and subnet flood detection to handle various DDoS traffic types. 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....

This course is one of the best course related to Network security. Additional resources were very useful especially the thesis about A2D2 network. Questions are also very nice and conceptual.

Week 3 parts could be remade as they are not very clear. I had difficulty in understanding the accent of the instructor but the subtitles were great help. A good course with lots of resources and in-depth clarity of mostly all concepts.

I noticed that not a single person mentioned how poorly this course was written. There are numerous typos throughout the course: spelling mistakes, grammar mistakes, poor sentence structure, and so on. A few of the quizzes even have incorrect answers. I looked up Dr. Chow and I see that he earned his PhD way back in 1985 at the University of Texas, so why is his English still so poor? I mean no disrespect, but by now one would think that his English would be almost perfect. Even stating that, why didn't he have anyone proofread his writing and fix it? However, if someone else wrote the course, then why did he allow so many errors in the course? It's just mind-boggling. I'm here to learn, not to decipher broken English. I could understand if this course were from another country, but it's from the University of Colorado system, so the course should have been much better written. Anyway, I gave the course two stars, since despite the poor writing, there is useful information in it, otherwise it would be a one star class to me for sure.

Instructor is very knowledgeable and a very good expert in the field, but his accent is extremely heavy and unintelligible at times, making learning a bit hard. Turning on English subtitles will help, but even the subtitles are mislabeled due to the instructor's heavy accent. Also, the quizzes are broken - when you give a correct answer, the system will mark it as wrong at varying times times, while saying that you gave the correct answer (in red, losing you points). Very frustrating experience with the quizzes. Finally, the course probably needs updating, it seems to be 7 years old? Most of the videos it links to for study are from 2017 and earlier.
