The employment outlook for network security engineers is very optimistic. Not only the national policy to give support, and employment demand is growing steadily, and salary advantage is also very obvious, and through their own efforts, can also rise from the grass-roots technicians to have a certain level of technical managers. According to the Research Report on the Status of Information Security Practitioners in China issued by China Information Security Evaluation Center, there is a huge shortage of information security practitioners, and the serious imbalance between supply and demand has pushed up the overall salary level. The average salary level of domestic information security practitioners is between 122-178,000 yuan, which is higher than the national average annual salary of professional and technical personnel and information technology practitioners, and the salary advantage is very obvious. Many large or mega enterprises have begun to gradually establish their own professional security teams to cope with the daily threats and emergencies of network security faced by the enterprise. Enterprise demand is mainly focused on security management, security operations and maintenance, research and development and testing, penetration testing and vulnerability mining, emergency response, chief security officer and other positions.
