Abstract

A method and device for preventing HTTP proxy attacks provided by the present application, the method is applied to a network security device, and the method includes: the network security device receives an HTTP request message, and parses out the message of the HTTP request message header; inquire whether there is a proxy field in the message header; if there is a proxy field in the message header, obtain the ip of the original client in the proxy field; update the quantity of the ip, and judge Whether the updated ip number conforms to the preset rule; if the updated ip number meets the preset rule, intercept the message corresponding to the ip. By applying the embodiment of the present application, the real attacker can be identified, so as to accurately intercept the HTTP request message sent by the attacker.

Description

technical field [0001] The present application relates to the technical field of network security, in particular to a method and device for preventing HTTP proxy attacks. Background technique [0002] With the continuous development of network technology, there are more and more network attacks, how to effectively prevent network attacks becomes very important. [0003] A network (Web) server (hereinafter referred to as a server) is extremely important in Internet applications, and it can provide services such as web page browsing, email sending and receiving, and network resource downloading. Protocol (Hypertext Transfer Protocol) protocol, so the server will often be attacked by the network. [0004] In the prior art, the protection against network attacks is mainly based on the source ip to count the rate of request packets. The basic processing flow is to parse the source ip carried in the HTTP request message, and then count the packets corresponding to the source ip ...
