With the rapid development of network information technology, its security protection system is increasingly being valued by various colleges and universities. How to strengthen the safety management of network information resources of campus network has become a research hotspot and difficulty. This study proposes a design of the fortress machine network architecture based on the main and standby redundancy, and takes the fortress machine into the management work of the university network information security. We also summarize the security management problems. The paper analyzes various fortress machine core management functions, and the fortress machine is introduced to the WAF protection system between the school and the core of the data center. It gives the core link configuration and code as well as the summary in the end.
