4. Coordinate the customized implementation, deployment and development of the solution, and assume that the solution is online.

5. Be responsible for coordinating the pre-sales and after-sales support of the company's network security projects.

2. What are the jobs of network security engineers?

Network security is also a part of national security in theory, and network security engineers are also very important. At present, there are many jobs for network security engineers, which can be summarized as network security engineers, network security analysts, data recovery engineers, network architecture engineers, network integration engineers, network security programming engineers and many other jobs.

Third, the requirements of network security engineers

Bachelor degree in computer application, computer network, communication, information security and other related majors, with more than three years working experience in network security field.

2. Proficient in network security technology: including port, service vulnerability scanning, program vulnerability analysis and detection, authority management, intrusion and attack analysis and tracking, website penetration, virus Trojan horse prevention, etc.
