I have been working on Java for 3 years. Now I want to switch to network security. From the moment I had this idea, it became deeper and deeper. I have no basic knowledge of network security. I just played around with software written by others in high school (script kiddie).
Because the company moved, I just resigned from my last job. Are you now looking for a job in Java and then studying on your own? Or whatever. . confused. . .
Three years in the Internet industry should be considered an "old man", and employers prefer people of this age to apply for managers and or senior engineers. Moreover, as we grow older, our learning ability and logical thinking are declining, and the effect of mastering knowledge may not be very satisfactory. Moreover, the IT industry is seriously involved, and many companies are laying off a large number of people and recruiting a lot of people, so it is right to change careers! Internet security has no requirements for academic qualifications or foundation, and is very tolerant to all ages! The salary is high and the threshold is low. Due to the ratio of talent supply and talent gap in the industry, network security has low requirements for practitioners’ experience, and most of them have no restrictions on practitioners’ academic qualifications. Employment directions are flexible and changeable. Currently, the Internet, new energy, financial securities , electronic technology and other industries are in urgent need of network security talents. Because of the importance of network security, each industry has also spawned different demand directions. Practitioners can choose their own careers according to their own preferences.
Cybersecurity Industry Analysis
The top 10 majors with the highest monthly income for college graduates in 2022
Undergraduate computer majors and higher vocational automation majors have higher monthly incomes. The monthly incomes of the 2022 undergraduate computer majors and higher vocational automation majors are 6,863 yuan and 5,339 yuan respectively. Among them, the starting salary of undergraduate computer majors is basically the same as that of the 2021 class, and the monthly income of higher vocational automation majors has increased significantly. The 2022 class overtook the railway transportation major (5,295 yuan) to rank first.
Looking at the major specifically, the major with the highest monthly income for the 2022 undergraduate class is information security (7,579 yuan). Compared with the class of 2018, undergraduate majors related to artificial intelligence such as electronic science and technology and automation performed well, with starting salaries increasing by 19% compared to five years ago. Although data science and big data technology are new majors in recent years, they have performed well and have ranked among the top three majors with the highest monthly income for 2022 undergraduate graduates six months after graduation. French, the only humanities and social sciences major that entered the top 10 highest-paying undergraduates five years ago, has dropped out of the top 10.
“There is no national security without cybersecurity.” At present, network security has been elevated to the level of national strategy and has become one of the most important factors affecting national security and social stability.
Characteristics of the network security industry
1. The employment salary is very high and the salary increases quickly. In 2021, Liepin.com announced that the employment salary in the network security industry is the highest per capita in the industry, 337,700!
2. There is a large talent gap and many employment opportunities
On September 18, 2019, the official website of the "Central People's Government of the People's Republic of China" published: my country's demand for cyberspace security talents is 1.4 million, but major schools across the country train less than 1.5 million people every year. Liepin.com’s “Cybersecurity Report for the First Half of 2021” predicts that the demand for network security talents in 2027 will be 3 million. Currently, there are only 100,000 employees engaged in the network security industry.
The industry has huge room for development and there are many jobs
Since the establishment of the network security industry, dozens of new network security industry positions have been added: network security experts, network security analysts, security consultants, network security engineers, security architects, security operation and maintenance engineers, penetration engineers, information security management Officer, data security engineer, network security operations engineer, network security emergency response engineer, data appraiser, network security product manager, network security service engineer, network security trainer, network security auditor, threat intelligence analysis engineer, disaster recovery professional , Practical attack and defense professionals...
Great career value-added potential
The network security major has strong technical characteristics, especially mastering the core network architecture and security technologies at work, which has an irreplaceable competitive advantage in career development.
As personal abilities continue to improve, the professional value of the work they do will also increase with the enrichment of their experience and the maturity of project operations, and the room for appreciation will continue to increase. This is the main reason why it is popular with everyone.
To a certain extent, in the field of network security, just like the medical profession, the older you get, the more popular you become. Because the technology becomes more mature, your work will naturally be taken seriously, and promotion and salary increases will come naturally.

Getting Started with Zero Basics
For students who have never been exposed to network security, we have prepared a detailed learning and growth roadmap for you. It can be said to be the most scientific and systematic learning route. It will be no problem for everyone to follow this general direction.
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 learn them all, you will have no problem taking on private work.
2. Video tutorial
Although there are many learning resources on the Internet, they are basically incomplete. This is a video tutorial on network security that I recorded myself. I have accompanying video explanations for every knowledge point in the roadmap above. [Click to receive the video tutorial]
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 also more than 200 e-books[Click to receive it Technical Documentation]
(They are all packaged into one piece and cannot be expanded one by one. There are more than 300 episodes in total)
