Embodiment Construction

[0024] see figure 1 , which is a flow chart of a method for proxy detection provided in the embodiment of the present application, the method includes the following steps:

[0025] 101. Obtain request information of a traffic packet.

[0026] According to the existing network transmission protocol, the traffic message is decoded at the network layer and the transport layer to obtain the request information of the flow message. Request information includes destination IP, destination port, and transport layer payload.

[0027] The target IP refers to the proxy IP in the traffic packet. Since all network devices in the Internet are equipped with IP, different network devices can be accessed through IP to realize the interconnection of network devices. The target IP in the traffic message may be obtained directly or through domain name resolution. In the embodiment of the present invention, the method for obtaining the target IP in the traffic message is not limited.

Abstract

The invention discloses an agent detection method and device, relates to the technical field of the internet, and aims to solve the problem that the agent detection accuracy is low. The method in the invention mainly comprises the following steps of: obtaining request information of a flow message, wherein the request information includes a target IP, a target port and a transmission layer load; judging whether the target IP and the target port exist in a pre-set network agent database or not; if so, determining that the flow message is network agent flow; if not, according to the transmission layer load, judging whether the flow message is network agent flow or not; and, controlling the flow message according to pre-set strategy configuration by judging whether the flow message is the network agent flow or not. The agent detection method and device disclosed by the invention are mainly used for detecting whether the network request needs to access the internet through a network agent server or not.

Description

technical field [0001] The present application relates to the technical field of the Internet, and in particular to a method and device for proxy detection. Background technique [0002] In the field of Internet technology, a network proxy can be used to access the Internet. The network proxy method is used to improve the access speed and access the blocked network. When using a network proxy to access the Internet, all network traffic must pass through an intermediate server, which makes the network environment itself have certain security risks. Therefore, proxy detection is particularly important in the process of accessing the Internet. [0003] In the prior art, a method of recording and analyzing a data packet ID (Identification, identity identifier) ​​is usually used. Record and analyze the packet ID, record the loopback time, and calculate the loopback time difference between two adjacent sending loopbacks, and compare the loopback time difference with the threshol...
