How to plan for network security
If you are a newbie in the security industry, I suggest you start with network security or web security/penetration testing. First, the market demand is high, and second, it is relatively mature and easy to get started.
It is worth mentioning that when learning network security, you must first study the network and then security; when learning Web security, you must first study the Web and then security.
Security does not exist independently, but is an upper-layer application technology based on other technologies. Without this foundation, it is easy to turn into talking on paper and "knowing what is happening but not knowing why." It is also difficult to go far on a safe career path.
If you are originally engaged in network engineering operation and maintenance, you can choose to get started in the network security direction; if you are originally engaged in program development, it is recommended to choose the Web security/penetration testing direction to get started. Of course, you have learned to a certain extent or have certain work experience, and different directions The technical coupling will become higher and higher, and everyone needs to know a little bit about each direction.
According to the above list of network security skills, it is easy to see that network security requires exposure to far more technologies. Common skills need to be learned: peripheral management capabilities, phishing remote control capabilities, domain penetration capabilities, traffic analysis capabilities, vulnerability mining capabilities, and code auditing. Ability etc.
Many people come up and say they want to learn hacking, but they start learning without even knowing the direction. In the end, they just end up in vain! Hacking is just a big concept in network security, which includes many directions, and different directions require different learning content.
Network security can be further subdivided into: network penetration, reverse analysis, vulnerability attacks, kernel security, mobile security, cracking PWN and many other sub-directions. Today's article mainly focuses on the direction of network penetration, which is the main technology of "hackers" as everyone knows it. Other directions are for reference only. The learning routes are not exactly the same. If I have the chance, I will sort it out separately.
Cybersecurity learning route
The following is a summary of a set of learning routes suitable for zero-level network security. It is suitable for fresh graduates and career changers. After learning, the minimum is 6k! Even if you have poor foundation, if you can take advantage of the good development momentum of network security and continue to learn, it is not impossible to find a job in a big company and get a million-dollar annual salary!

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.

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.
