Design and Implementation of a Network Emergency Response Mechanism Based on Flow and Application

With the rapid development of computer networks and information systems, network security becomes more and more serious. Based on the research on computer local area network (LAN), we present an emergency protection mechanism based on link flow and application for network security. Problems of existing LAN monitoring, management, and security devices are discussed, and the procedure of emergency response mechanism includes three stages is proposed. The emergent solutions for the communication, virus, server response, data protection, and incident are brought forward under different conditions.
