Preface
Now you can see many headlines claiming that you can switch to the field of network security within three months and become a network security engineer with a monthly income of 15K. So, how much network security knowledge can you learn in 3 months? Is it really possible to become a network security engineer?
I think it is ok. But you definitely need one: a systematic learning route and a scientific learning plan
Including starting from school, I have been on the road to network security for 10 years. Whether I was doing security research in school or working on kernel security products and binary vulnerability attack and defense at Baidu and 360 after graduation, I know all about it. The importance of learning methods. Without a good learning path and good learning methods, you will often achieve half the result with half the effort.
Looking back, I have stepped into many pitfalls and walked many wrong roads. I hope my experience can be helpful to everyone, especially the freshmen in the graduation season. If anyone wants to engage in network security, I suggest you like it and save it.
1: Learning route
Mr. Lu Xun once said: "If you go in the wrong direction, your efforts will be in vain. " Many novices on the Internet say they want to learn hacking, but they start learning without even knowing the direction, and in the end they will just end up in vain! Hacking is a big concept that includes many directions, and different directions require different learning content.

Preschool speech
- 1. This is a path to persevere. If you are enthusiastic for three minutes, you can give up and move on.
- 2. Practice more and think more, don't know anything without leaving the tutorial. It is best to complete the technical development independently after reading the tutorial.
- 3. Sometimes when we search Google or Baidu, we often fail to meet a kind-hearted master who will give you answers without chatting.
- 4. If you encounter something you really don’t understand, you can put it aside for now and solve it later.
2: Enterprise-level learning plan for zero-based entry into network security
Junior network engineer

Congratulations, if you learn this, you can basically work in a network security-related job, such as penetration testing, web penetration, security services, security analysis and other positions; if you learn the standard protection module well, you can also work as a standard protection engineer. Salary range 6k-15k
So far, about 1 month. You've become a "script kiddie." So do you still want to explore further?

7. Script programming (beginner/intermediate/advanced)
in the field of cybersecurity. The ability to program is the essential difference between "script kiddies" and real hackers . In the actual penetration testing process, in the face of complex and changeable network environments, when commonly used tools cannot meet actual needs, it is often necessary to expand existing tools, or write tools and automated scripts that meet our requirements. At this time, Requires certain programming skills. In the CTF competition, where every second counts, if you want to effectively use homemade script tools to achieve various purposes, you need to have programming skills.
For beginners, it is recommended to choose one of the scripting languages Python/PHP/Go/Java and learn to program common libraries; build a development environment and choose an IDE. Wamp and XAMPP are recommended for PHP environments, and Sublime is highly recommended for IDEs; ·Learn Python programming , the learning content includes: grammar, regularity, files, networks, multi-threading and other common libraries. We recommend "Python Core Programming", don't read it all; · Use Python to write exploits for vulnerabilities, and then write a simple web crawler; · PHP basic syntax Learn and write a simple blog system; Be familiar with the MVC architecture, and try to learn a PHP framework or Python framework (optional); ·Understand Bootstrap layout or CSS.
8. Super Internet worker
This part of the content is still relatively far away for students with zero foundation, so I won’t go into details and post a rough route.

Conclusion
The network security industry is like a river and lake, where people of all colors gather. Compared with many well-known and decent people in European and American countries who have a solid foundation (understand encryption, know how to protect, can dig holes, and are good at engineering), our country's talents are more of a heretic (many white hats may be unconvinced), so in the future talent training and In terms of construction, it is necessary to adjust the structure and encourage more people to do "positive" "system construction" that combines "business" with "data" and "automation". Only in this way can we quench the thirst for talents and truly provide comprehensive services to society. The Internet provides security.
Special statement:
This tutorial is purely technical sharing! The purpose of this book is by no means to provide technical support to those with bad intentions! We also do not assume any joint liability arising from the misuse of technology! The purpose of this book is to awaken everyone's attention to network security to the greatest extent, and to take corresponding security measures, thereby reducing the economic losses caused by network security! ! !
