Method for detecting network agent based on instant messaging software

Abstract

The invention discloses a method for detecting a network agent based on instant messaging software. The method comprises the steps that a message of the instant messaging software is detected by a serial network detector in real time and the type of the message is judged; if the detected message is an on-line message or an off-line message, a source address of the on-line message or the off-line message of the instant messaging software is analyzed and acquired; the on-line number of the instant messaging software under the source address is recorded; and if the number of the instant messaging software under the source address is greater than a preset value, the source address is an address of the network agent. The instant messaging software is QQ messaging software. The method pays close attention to an application layer, so that modification of acting equipment in a network layer and a transmission layer is avoided, and the detection accuracy is ensured; and the detection misjudgment is corrected intelligently by the on-line and off-line feature detection of the instant messaging software, so that the detection timeliness and the accuracy are high.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a method for detecting network agents based on instant messaging software. Background technique [0002] Network sharing is a social organization that takes computers and other terminal equipment as the carrier and uses the Internet to face the public for information exchange and resource sharing. At present, many users connect multiple computers through a router or NAT device, pretending to be a computer to access the Internet, that is, forming a proxy sharing network in the network. The network proxy allows multiple users to share one network address. Although the network resources are shared, the user's access to the Internet cannot be controlled, which brings certain troubles to the network operator. [0003] At present, the commonly used method for detecting network proxy is to detect the ID number of the IP data packet, compare the ID number, and if it does not i...

AI Technical Summary

Problems solved by technology

This method is to detect the network layer or transport layer of the network. However, many network proxy devices modify the ID number of the IP data packet to make it linearly increasing, which makes the above technology unable to detect whether there is a network or not. proxy, leading to missed detection, reducing the accuracy of detection, and causing security risks for network users
