Embodiment Construction

[0054] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0055] The domain name filtering system of the present invention includes a filtering center subsystem and a domain name server with a filtering proxy subsystem. The filtering center subsystem generates corresponding filtering commands for each filtering proxy subsystem according to the blacklist domain names that need to be filtered provided by the user, and the domain name server with the filtering proxy subsystem generates filtering commands according to the filtering central subsystem. Realize filtering of blacklisted domain names. In actual implementation, the filtering center subsystem is implemented in the form of a software server installed on a computer device, while the filtering proxy subsystem can be installed in all domain name servers except the root domain name server in the form of proxy software. Since the domain name server...

Abstract

The invention provides a filtering system for domain name, comprising a domain name server for achieving the domain name filter installed with a filtering proxy sub system and a filtering centre sub system for generating the filtering directive. The sub system filter center filter based on information entered by the user in light of filter sub system status information agent for the filtering agent sub system command to generate the corresponding filter; domain filtering proxy server sub system analysis and implementation of the filter orders received, according to modify the content filter command of the domain name server configuration file, the domain name server configuration file under the name of the content filter to filter the domain name. The present invention does not require the operation of the existing domain name server to do any changes, which are easy to implement, easy to maintain the advantages of the existing domain name and server stability and performance have no effect.

Description

technical field [0001] The invention relates to the field of network security, in particular to a domain name filtering system and method. Background technique [0002] With the rapid development of the Internet, the number of registered and used Internet domain names (DNS) has also increased rapidly. In 2007, the number of registered Internet domain names in my country has reached 11.93 million, with an annual growth rate of 190.4%. At the same time, domain names have gradually become the main tool used by hackers. Using domain names, hackers can flexibly and covertly carry out malicious activities such as hanging horses on large-scale webpages, controlling botnets, and phishing. Thereby tampering with the content of the webpage, stealing important internal data, and more seriously, implanting malicious codes in the webpage (commonly known as "webpage hanging horse"), causing more website visitors to be violated. In order to effectively contain or eliminate malicious infr...
