Open Source Initiative (New)

To attract more people to contribute to the SEED project, I launched this open-source initiative. All the source files of the SEED labs are now open sourced. We welcome everybody to join. Together, we can develop more interesting hands-on labs and better serve the cybersecurity education around the world:


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 32 hours of lecture videos based on the SEED labs and the SEED book. They are available on Udemy as two courses, covering 22 SEED labs and 17 chapters, with a lot of hands-on demonstration. More lectures are being recorded, so stay tuned.

SEED Workshop

We hold SEED Workshops to provide hands-on training to the instructors around the world. In 2020, we held 2 online workshops. If you are interested in sponsoring a workshop for your organization or community, please contact us.
