Wired network monitoring system

Abstract

The invention relates to a wired network monitor system, which comprises M independent information collectors, a data center and M independent monitored network units, wherein the output terminal of each independent information collector is connected with the input terminal of the data center; the input terminals of the M independent information collectors are connected with the output terminals of the M independent monitored network units; each independent monitored network unit is connected with N independent users; and the N independent users corresponding to each monitored network units are different from the N independent users corresponding to other monitor network units. The wired network monitor system has the advantages that the data collection and analysis is achieved by the information collectors at the outlet of each network unit by adopting a multi-step data processing and centralized control manner; and the information collection policy and the data summarization are achieved by the data center, so that the processing of massive data is distributed to different units to achieve maximally centralized control, thereby reducing the data quantity to be stored. The wired network monitor system can work normally only using a simple network connection, and has the advantages of convenient implementation and simple maintenance.

Description

Technical field

[0001] The invention relates to a method for monitoring various audio and video bad information, harmful information and reactionary information produced, distributed, disseminated and accessed on the Internet / Intranet network, and detects, locates and alarms those who manufacture and distribute bad information Online bad information detection and control system. It belongs to the field of information monitoring, investigation and control technology. Background technique

[0002] Traditional firewalls, IDS and other devices only analyze data headers, and control network parameters such as IP addresses, ports, MAC addresses, or protocols. They work at the link layer of the network, so they cannot update the information content on the Internet. Responses cannot fundamentally solve the dissemination of bad information. The adopted firewall filtering, address library filtering and other network information detection and control methods still have many defects, such as...
