Method and device for diagnosing validity of active domain names in IDC computer room

Abstract

The invention discloses a method and a device for diagnosing the validity of active domain names in an IDC computer room. The method comprises: by comparing the acquired real server IP information with all server IP information in the local IDC computer room, judging whether the acquired real server IP belongs to the local server IP; by comparing the acquired real server IP information with the display server IP Information, to determine whether the obtained display server IP belongs to the real server IP; when the obtained real server IP belongs to the local server IP and the display server IP belongs to the real server IP at the same time, it is judged that the active domain name to be tested is a valid active domain name. The method provided by the present invention judges the validity of the active domain name, can effectively filter out invalid domain names, domain names that can be accessed but do not correspond to the IP address of the display server, and domain names in non-local IDC computer rooms, so as to ensure the authenticity of the active domain name to the greatest extent. sex and accuracy.

Description

technical field [0001] The invention relates to the technical field of information security management, in particular to a method and device for diagnosing the validity of active domain names in an IDC computer room. Background technique [0002] Internet Data Center ("IDC" for short) is an enterprise model that specializes in providing network resource outsourcing and professional network services, and is an inevitable result of a more detailed division of labor in the Internet industry. IDC information security management system is an information security management system built by IDC business operators with basic data management, access log management, information security management and other functions to meet the information security management needs of IDC business operators and telecommunications management departments. [0003] Information security management includes active resource monitoring and management, illegal website management, and illegal information moni...

Problems solved by technology

[0004] Theoretically, the public information transmitted on the link is active domain name and active IP information, but there is a big gap between reality and theory. The public information transmitted on the link includes not only active domain name and active IP information, but also Part of the data of inactive domain names and inactive IPs; this part of data may be scanning data, attack data, forged data, etc., but this part of data is often much more than the data of active domain names and active IPs. These data will not only affect network information The security management system is a burden, and it is very bad for the user experience and the use of the network information security management system. Therefore, a method for diagnosing the validity of active domain names is needed to deal with the above problems
