` How to learn hacking & network security

As long as you like my article today, my private network security learning materials will be shared with you for free. Come and see what is available.

1. Learning roadmap

There are a lot of things to learn about attack and defense. I have written down the specific things you need to learn in the road map above. If you can complete them, you will have no problem getting a job or taking on a private job.

2. Video tutorial

Although there are many learning resources on the Internet, they are basically incomplete. This is an Internet security video tutorial I recorded myself. I have accompanying video explanations for every knowledge point in the roadmap above.

The content covers the study of network security laws, network security operations and other security assessments, penetration testing basics, detailed explanations of vulnerabilities, basic computer knowledge, etc. They are all must-know learning contents for getting started with network security.

(They are all packaged into one piece and cannot be expanded one by one. There are more than 300 episodes in total)

3. Technical documents and e-books

I also compiled the technical documents myself, including my experience and technical points in participating in large-scale network security operations, CTF, and digging SRC vulnerabilities. There are more than 200 e-books. Due to the sensitivity of the content, I will not display them one by one.
