Hackers and information disclosure have caused great network and information security threats to the campus network of colleges and universities. In the network security response mechanism and process, the rapid isolation and seizure of the accident point can greatly reduce the negative impact of the hidden risks on the entire campus network. Bearing this requirement in mind, this study has implemented a set of automatic management system by combining software and hardware. Using black-hole routing and OSPF routing distribution mechanism, and supporting script server and identity authentication system, we can isolate and seal external attack sources or internal failure point, thus promptly eliminate secondary hazards. At the same time, ACL control and OAuth authentication ensure the overall system security.
