Problems solved by technology

[0003] However, when other terminal devices steal the IP address of the successfully authenticated terminal device to send a message, the access device in the Web authentication mechanism cannot judge the validity of the message, so that it will process the illegal message normally, resulting in Such network attacks

Abstract

The invention provides a method and a device for preventing network attack based on a Web authentication technology. The method comprises the steps of receiving a message through a port which does not open Web authentication locally; judging whether a source IP address of the message hits a preset online IP list or not, wherein the online IP list contains a plurality of IP addresses of terminal equipment which are already successfully authenticated on a port which already opens Web authentication locally; and determining the message is an illegal message if the source IP address of the message hits the online IP list, and discarding the message. By applying the embodiment of the invention, access equipment can be prevented from initiating a network attack behavior through embezzling an IP address of terminal equipment which passes Web authentication.

Description

technical field [0001] The present application relates to the field of computer communication, in particular to a method and device for preventing network attacks based on Web authentication technology. Background technique [0002] Web authentication technology is an authentication method based on user name and password. In the mechanism of Web authentication, access control can usually be performed at the access device and the key data entrance that needs to be protected, and the terminal device of the user who wants to access Internet resources is authenticated. After the authentication is successful, the user's terminal device is allowed to access the Internet. Resources, in order to realize the control of the user's terminal equipment to access Internet resources. [0003] However, when other terminal devices steal the IP address of the successfully authenticated terminal device to send a message, the access device in the Web authentication mechanism cannot judge the v...
