Mô tả

From Morris worm to Mitnick attack; from Mafia boy to Kaminsky attack; from Pakistan's hijacking of YouTube to Syria's shutting down of its own Internet. These are so many attacks on the Internet. If you want to learn how the Internet works, how it can be attached, and more importantly, how you can defend against these attacks, then this course is for you.

In this course, we systematically study each layer of the TCP/IP protocols, discuss the vulnerabilities in its design and implementation, and demonstrate how to exploit the vulnerabilities in attacks. Many classic attacks are covered in this course, with great technical details. The course won't just teach you the high-level concepts and theories; it would dive into the low-level technical details and fundamentals, so you can fully understand how exactly things work.

The course emphasizes hands-on learning. For each attack covered, students not only learn how the attack works in theory, they also learn how to actually conduct the attack, in a contained virtual machine environment. The hands-on exercises developed by the instructor are called SEED labs, and they are being used by over 1000 institutes worldwide. The course is based on the textbook written by the instructor. The book, titled "Computer & Internet Security: A Hands-on Approach, 2nd Edition", has been adopted by over 210 universities and colleges worldwide.
