Computer network monitoring device

Abstract

The invention discloses a computer network monitoring device comprising a total control module for information processing and a network server for monitoring an external network, wherein the network server is connected with the total control module, and a firewall is arranged between the network server and the total control module, the firewall is used for analyzing and extracting scanning features and preventing illegal users from entering an intranet; and a video collection module, a video buffer module, a network access module and a prompt sending module are arranged in the network server.A data storage module is connected with the total control module, the data storage module can perform hierarchical storage on big data, and the hierarchical storage is realized by a real-time data layer and a historical data layer and comprises a data collection module and a hierarchical storage module. The computer network monitoring device disclosed by the invention can store large batches of monitoring data, realizes safe switching between multiple networks and adopts an early warning mode before each network disconnection and switching in advance, so that a user can make corresponding preparations in advance.

Description

technical field [0001] The invention relates to a network monitoring device, in particular to a computer network monitoring device. Background technique [0002] With the rapid development of computers and networks, network security has become a key issue in the field of computer networks and their applications. However, traditional network monitoring has insurmountable defects. First of all, the existing computer network monitors have problems of insufficient security performance and single function, so they bring hidden dangers to the security of user computer information, and problems such as network information theft and information attacks exist and occur all the time; secondly, the data of network monitoring Limited, unable to monitor large batches of data, and unable to adapt to the current distributed network environment. Contents of the invention [0003] Purpose of the invention: the purpose of the present invention is to provide a computer network monitoring de...
