Current status of network security industry development
Network security refers to the protection of data in information systems (including hardware, software, infrastructure, etc.) from unauthorized access, disclosure, destruction, modification, review, inspection, record or destroy. The main objectives of network security include the realization of information authenticity, confidentiality, integrity, availability, and non-repudiation. Generally speaking, the network security business mainly includes security products (including security hardware and security software) and security services.
Global governments and enterprises are paying more and more attention to network security year by year , and the market has great potential for development. With the rapid expansion of the IT industry, governments and enterprises in various countries are gradually increasing their attention to security. Overall, the global network security industry is still in a stage of rapid development, and the scale of the network security industry continues to grow.
According to the "2022 V1 Global Cybersecurity Spending Guide" released by IDC , the total investment in global cybersecurity-related hardware, software, and services is expected to reach US$151.95 billion in 2021. During the period 2021-2025, global cybersecurity-related spending will achieve a compound annual growth rate of 10.40%, and is expected to reach $223.340 billion in 2025. Global governments and enterprises are paying more and more attention to network security year by year, and the market has great potential for development.
In terms of business types, in recent years, the market size of global network security products has surpassed that of network security services. According to the "White Paper on China's Network Security Industry" released by the China Academy of Information and Communications Technology in January 2022 , after the global network security product market accounted for more than the network security service market for the first time in 2019, this trend will be further deepened in 2020.
In 2020, the global network security product market size and security service market size will be US$71.59 billion and US$65.070 billion, respectively. The main reason is that the continuous introduction of privacy security and other compliance requirements in various countries drives enterprises to actively deploy related products such as data leakage prevention and data control.
In recent years, driven by downstream demand and government policies, the scale of my country's network security industry has continued to develop. With the rapid development of information technology and Internet technology and the in-depth integration with all aspects of society, network security issues have occurred frequently and become increasingly complex in recent years. trend. The Chinese government pays more and more attention to network security, and network security has become a national strategy , and the requirements for network security have been strengthened at the system and regulatory levels.
In addition, with the promotion of digital transformation in all walks of life, the relationship between various businesses and IT is getting closer , and the effect of network security construction and operation is getting more and more attention. In recent years, driven by downstream demand and government policies, the scale of my country's network security industry has continued to grow. According to the statistics of the China Academy of Information and Communications Technology, the scale of my country's network security industry will reach 172.930 billion yuan in 2020, an increase of 10.60% compared with 2019; the industry scale is expected to reach 200.250 billion yuan in 2021, maintaining a high-speed growth trend.
China's network security market is dominated by security hardware , and the demand for network security has maintained rapid growth. The market composition of China's network security industry products and services is quite different from that of the global market. In the global network security market, security services and security products (including security software and security hardware) market size is relatively balanced, while China's network security market is dominated by security hardware. According to the "2022 V1 Global Network Security Expenditure Guide" released by IDC, in the next five years, network security hardware will still be the first-tier submarket with the highest proportion in China's network security market, accounting for more than 40.00% of the scale; The growth momentum of the software market will remain strong, with a five-year compound annual growth rate of 23.90%.
According to IDC's forecast, China will become the fastest growing market for cyber security in the world in the next five years , and the compound growth rate from 2021 to 2025 will exceed 20%. Among them, the market size of network security analysis, intelligence, response and orchestration will exceed the market size of identity and digital trust software in 2024 and become the largest secondary software submarket. In addition, in the context of the accelerated pace of enterprises migrating to the cloud, the software security gateway market will usher in a high-speed development period with a compound growth rate of more than 25%.

Friends who need it can pay attention to me and send it automatically in the background~
1. Network security (hacker) learning route
The network security (hacker) learning route forms a summary of all knowledge points in the field of network security. Its usefulness lies in that you can find corresponding learning resources according to the above knowledge points to ensure that you learn more comprehensively.
2. Network security tutorial video
When we watch videos and learn, we can’t just move our eyes and brain without using our hands. A more scientific learning method is to use them after understanding. At this time, the hands-on project is very suitable.
3. Practical cases of network security CTF
Optical theory is useless, you have to learn to follow along, and you have to practice to apply what you have learned to practice. Here are CTF&SRC data&HW data. After all, actual combat is the only criterion for testing the truth~
4. Network Security Interview Questions
Finally, all our actions are for employment, so the key step is the content of our interview questions, so the interview question section is an indispensable part of us. What I prepare for you here is what I prepared during the interview. data of.

Internet security is actually not difficult, but the hard part is to persist and believe in yourself . My experience is that since you have chosen Internet security, you have to believe in it, and believe that it can become an efficient channel for you to advance in the future, so that you will have more confidence in yourself. Learn to persevere in times of difficulty.
Opportunities belong to those who are prepared. This is an era of strength. The gap between people does not lie in IQ, but in how to use spare time. As long as you want to learn, it is never too late to start. Don’t worry about this or that. You just need to work hard and leave the rest to time!
