SEED Internet Emulator (Code, Videos)

We have developed an open-source Python framework, which can be used to create emulation of the Internet. It opens a door for many new activities that are difficult to perform in the current SEED platform, including BGP attacks, large-scale DNS attacks, Blockchain, Botnet, Dark-net, etc. We welcome everybody to join us in this project. The same videos are also hosted on Bilibili for Chinese viewers.


SEED Labs

We have developed over 30 labs that cover a wide range of topics in computer and information security, including software security, network security, web security, operating system security and mobile app security. More labs are currently being developed.

SEED Books

I have written a textbook based on the SEED labs and my 18 years of teaching experience. The book takes a hands-on approach: for each security principle, specially designed activities are used to help explain the principle. The book is available on Amazon.

SEED Lectures

I have recorded 40 hours of lecture videos based on the SEED labs and the SEED book. They are available on Udemy as 3 courses, covering 26 SEED labs and 20 chapters, with a lot of hands-on demonstration. More lectures are being recorded, so stay tuned.

SEED Workshops

Since 2015, I held SEED Workshops every year to help others improve hands-on skills in cybersecurity. I have trained more than 800 instructors. If your institute or organization is interested in this program, click the following button for more information.
