What are the employment directions of network security?

As an IT practitioner and computer professional educator, let me answer this question.

First of all, from the employment direction of network security, it can be employed in many fields such as cloud computing, big data, Internet of Things and artificial intelligence. And with the gradual application of technologies such as cloud computing, the demand for security talents in these emerging technologies will gradually increase in the future, and the overall employment prospects are still relatively broad.

Taking the field of big data as an example, with the continuous improvement of data value, the importance of data security in the field of big data will gradually increase. For the big data technology system, big data without security is not far away, so beginners who are currently studying network security can also focus on learning relevant knowledge in the field of big data security.

In the era of 5G communication, the Internet of Things will usher in new development opportunities, and the Internet of Things is an important foundation of the industrial Internet, so a large number of enterprises in traditional industries will also build their own Internet of Things, so the Internet of Things is expected to become an important field of innovation and entrepreneurship. From the technical architecture of the Internet of Things, the current Internet of Things has six levels, of which only security occupies one level, and security is also an important support for the other five levels (equipment, network, Internet of Things platform, data analysis and application). So from this perspective, the Internet of Things will also become an important application field of network security.

From the content of network security, network security involves transmission security, storage security, operation and maintenance security and other fields. And it involves a wide range of knowledge, not only operating system, computer network, database and other knowledge, but also cryptography and other related content, so it is not only a large amount of knowledge, but also relatively difficult.

Finally, the work related to network security is not only related to technical systems (Internet of Things, big data, etc.). ), but also closely related to the application scenario, so the working boundary of security practitioners themselves is still relatively wide.
