Example Embodiment

[0046] Example one, a web site security defense system, such as figure 2 As shown, it is set in the public Internet, between the Web client and the protected Web site, so that Web client users-whether normal users or malicious users-can access the protected Web site through the Web site security defense system Web site.

[0047] The Web site security defense system of this embodiment adopts DNS takeover technology to achieve traffic traction of HTTP traffic, so that all HTTP traffic originally sent directly to a protected Web site must first flow through the Web site security defense system provided in this embodiment. Sending to a protected Web site, in this way, the Web site security defense system of this embodiment has the opportunity to perform security inspection on all HTTP traffic sent to the protected Web site. Due to the use of traffic traction technology, the physical network connection does not require the Web site security defense system to be connected between the ...

Abstract

The invention relates to a safety defense system of a Website, comprising a flow tractor and a Web safety detector, wherein the flow tractor is connected with a DNS (Domain Name Server) and is used for receiving the DNS domain name analyzing request of a client from the DNS, analyzing the domain name into the IP address of the Web safety detector and then returning to the client; and the Web safety detector is used for receiving HTTP (Hyper Text Transport Protocol) request information and carrying out intrusion detection on the HTTP request information, if no abnormal phenomenon is found, transmitting the HTTP request information to the Website pointed by the HTTP request information. The arrangement position of the safety defense system is not limited by serial arrangement and supports distributed arrangement, the configurations of the Web client and the Web server do not need to be modified so that the cost of safety defense is saved, and the safety defense system has good compatibility and strong scalability.

Description

technical field [0001] The invention relates to the field of network security, in particular to a Web site security defense system. Background technique [0002] The 23rd Statistical Report on Internet Development in China released by China Internet Network Information Center (CNNIC) shows that by the end of 2008, the number of websites in China had reached 2.878 million. In 2008, the number of Chinese websites increased by 91.4% compared with 2007, which was the fastest growth year since 2000. By the end of 2008, the total number of web pages in China exceeded 16 billion, an increase of 90% compared to 2007. The growth rate of the web page is basically the same as the growth rate of the website. [0003] But at the same time, the security situation of domestic Web sites is worrying. According to incomplete statistics, more than 60% of the websites in China have web security vulnerabilities, including various SQL injection vulnerabilities, cross-site scripting vulnerabili...
