besides the subject matter
People who are new to the computer industry orUniversity graduates of computer-related majors, many due to the lack of real-world experience, employment everywhere. Here we look at two sets of data:
-
The 2023 class of national college graduates is expected to reach 11.58 million, making the employment situation grim;
-
Data released during the National Cybersecurity Awareness Week shows that by 2027 there will be a shortfall of 3.27 million cybersecurity personnel in China.
On the one hand, the employment situation of fresh graduates every year is grim, and on the other hand, there is a million gap in cybersecurity talents.
On June 9, the 2023 edition of the Employment Blue Book (including the 2023 China Undergraduate Employment Report and the 2023 China Higher Vocational Student Employment Report) of McKesson Research was officially released.
Top 10 Majors with Higher Monthly Earnings for College Graduates in the Class of 2022
The monthly income of undergraduate computer science and senior automation majors is higher.The monthly income of undergraduate computer science and senior automation majors in the class of 2022 is 6863 yuan and 5339 yuan respectively. Among them, undergraduate computer class professional starting salary is basically the same as the 2021 session, senior automation class monthly income growth is obvious, the 2022 session of the counter overtake the railway transportation class (5,295 yuan) in the first place.
Looking specifically at majors, the higher monthly undergraduate income for the Class of 2022 is information security ($7,579). Compared with the class of 2018, electronic science and technology, automation and other undergraduate majors related to artificial intelligence are not bad, compared with five years ago, the starting salary increase have reached 19%. Data science and big data technology, although a new major in recent years but bright performance, has been among the top three undergraduate graduates of the class of 2022 in the higher monthly income six months after graduation majors. The only humanities and social sciences major that entered the top 10 undergraduate high salary list five years ago - French has dropped out of the top 10.
"There can be no national security without cybersecurity." At present, cybersecurity has been elevated to the height of national strategy and has become one of the crucial factors affecting national security and social stability.
Cybersecurity Industry Characteristics
1, employment salary is very high, fast salary increase 2021 hunting network released network security industry employment salary industry highest per capita 33.77 million!
2. Large talent gap and many employment opportunities
On September 18, 2019, the official website of the Central People's Government of the People's * published: the demand for cyberspace security talents in China is 1.4 million people, while the major schools across the country train less than 1.5W people each year. Hunting network "2021 first half of the network security report" predicts that in 2027 the demand for cybersecurity talents is 300W, and now there are only 10W people engaged in the network security industry.
There is a lot of room for growth in the industry and very many positions
Since the network security industry industry, then dozens of new network security industry positions: network security experts, network security analysts, security consultants, network security engineers, security architects, security operations and maintenance engineers, penetration engineers, information security administrators, data security engineers, network security operations engineers, network security emergency response engineers, data appraisal division, network security product managers Network Security Service Engineer, Network Security Trainer, Network Security Auditor, Threat Intelligence Analysis Engineer, Disaster Recovery Professional, Practical Attack and Defense Professional...
High potential for career advancement
The cybersecurity program is highly technical in nature, and in particular, mastery of the core network architectures and security technologies at work provides an irreplaceable competitive advantage in career advancement.
With the continuous improvement of personal ability, the professional value of the work engaged in will also be with their own experience and the maturity of the project operation, the appreciation space all the way up, which is also the main reason why it is welcomed by everyone.
In a way, in the field of cybersecurity, as in the case of doctors, the older you get, the better you get, because the more mature your skills become, the more your work is valued, and the more you get promoted, the more you get paid.
