I used to know it better in public security colleges. The post of network security management is very good. Network security management is actually the security supervision, detection and management of networks and information. It belongs to the public security department (good working environment, no danger) and belongs to civil servants. Wages are determined according to grades.
Get the same basic salary as the traffic police and criminal police at the same level in the same area.
Less responsibilities, less overtime pay and other benefits vary from region to region.
The development prospect depends on efforts+opportunities, which is basically the same as other management+technical civil servants.
Good luck and all the best!
