=========
Many people who are new to the computer industry or graduates of computer-related majors have encountered obstacles everywhere due to lack of practical experience. Let's look at two sets of data:
-
The 2023 national college graduates are expected to reach 11.58 million, and the employment situation is severe;
-
According to the data released by the National Network Security Publicity Week, by 2027, the shortage of network security personnel in my country will reach 3.27 million.
On the one hand, the employment situation of fresh graduates is severe every year, and on the other hand, there is a gap of one million cyber security talents.
On June 9, the 2023 edition of the Employment Blue Book of MyCOS Research (including the 2023 Employment Report for Undergraduates in China and the Employment Report for Higher Vocational Students in China in 2023) was officially released.
Top 10 Majors with Higher Monthly Salary for 2022 College Graduates
The monthly income of undergraduate computer science majors and higher vocational automation majors is relatively high. The monthly income of the 2022 class of undergraduate computer science and higher vocational automation majors is 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 of overtaking railway transportation majors (5295 yuan) ranks first.
Specifically, depending on the major, the major with a higher monthly income for undergraduates in 2022 is information security (7579 yuan). Compared with the class of 2018, undergraduate majors related to artificial intelligence, such as electronic science and technology, automation, performed well, and their starting salaries increased by 19% compared with five years ago. Although data science and big data technology are newly added majors in recent years, they have performed well, and have ranked among the top three majors with higher monthly income half a year after graduation for the 2022 class of undergraduates. The only humanities and social science major that entered the top 10 undergraduate high-paying list five years ago-French has dropped out of the top 10.
"There is no national security without cybersecurity". At present, network security has been elevated to the height 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 rises quickly. In 2021, Liepin.com released the highest employment salary in the network security industry, which is 337,700 yuan per capita!
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 needs 1.4 million cyberspace security talents, but schools across the country train less than 1.5 million people each year. Liepin.com's "Cyber Security Report for the First Half of 2021" predicts that the demand for cyber security talents will be 3 million in 2027, and there are only 100,000 employees currently engaged in the cyber security industry.
The industry has a lot of room for development and 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 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 , Actual combat offensive and defensive professionals...
Great career potential
The network security major has strong technical characteristics, especially mastering the core network architecture and security technology in the work, which has an irreplaceable competitive advantage in career development.
With the continuous improvement of personal ability, the professional value of the work will also increase with the enrichment of one's own experience and the maturity of project operation, and the appreciation space is bullish all the way, which is the main reason why it is popular with everyone.
To some extent, in the field of network security, just like the doctor profession, the older you are, the more popular you become. Because the technology becomes more mature, the work will naturally be valued, and promotion and salary increase are a matter of course.
