8. The development of network security
Network security is a popular career field, and with the continuous improvement of information technology, network security is becoming more and more important. Penetration engineers, security operation and maintenance engineers, etc. For those who want to enter the field of network security, they need to have solid computer foundation and security knowledge, and also need to continuously learn and master the latest technologies and tools.
1. There are many jobs and a wide range of development directions
①Employment environment: Network security can be engaged in related work in the fields of computer science and technology, information communication, e-commerce, Internet finance, e-government affairs, etc., and can also work in government agencies, institutions, banks, insurance, securities and other financial institutions, telecommunications, media and other related industries.
②Employment positions: network security engineer, penetration test engineer, code audit engineer, level protection engineer, security operation and maintenance engineer, security operation engineer, security service engineer, etc.
2. Competitive salary
As an emerging industry, the market demand for network security talents is far greater than the supply. If companies want to really recruit talents, they must have sufficient competitive advantages in salary and benefits. Therefore, salaries in the field of network security have also shown a steady growth trend in recent years.
3. Large space for career development
From the perspective of the main content of network security major learning, it includes Linux operation and maintenance, Python development, penetration testing, code auditing, level protection, emergency response, risk assessment, etc. It can be seen that the network security major is highly technical and has distinctive professional characteristics. It is one of the engineering majors that can learn real technology.
Therefore, in terms of career development, in addition to the large number of jobs, the network security major will be in the core position of the technical backbone in the workplace due to its strong professional and technical nature, and there is a lot of room for career development.
4. Great career value-added 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.
