Cybersecurity outlook
I don’t need to say much about the development and employment prospects of network security. As one of the majors with higher incomes for current graduates, network security also occupies a popular position in the field of career change. It mainly has the following career change advantages:
1. There is a large talent gap in the industry. By 2027, China's cybersecurity talent gap will reach 3.27 million.
2. The knowledge system is friendly, and students with relatively weak computer and English skills can also learn and get started
. 3. The entry threshold is low, and a college degree can be used to learn and find employment
. 4 .High salary starting point
5.Wide range of employment options, one major includes more than ten kinds of positions
There are abundant positions and a wide range of choices, which determine the level of career development . This is also one of the reasons why network security is so popular. In this article, I will plan for you how to systematically learn the major of network security. Friends who want to find a job or change careers, remember to like and save it~
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 a big concept that includes many directions, and different directions require different learning content.
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.
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.
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.

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 hacker
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. If you are interested in children's shoes, you can research it. If you don't understand the place, you can [click here] to join me and learn and communicate with me.

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 maximize everyone's attention to network security and take corresponding security measures, thereby reducing the economic losses caused by network security. ! ! !
