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

Abstract

The invention discloses a method and device for validity diagnosing of active domain names in an IDC computer room. The method for validity diagnosing of the active domain names in the IDC computer room comprises the following steps: judging whether an obtained real server IP belongs to a local server IP or not by comparing the obtained real server IP information with all server IP information of the local IDC computer room; judging whether an obtained displaying server IP belongs to the real server IP or not by comparing the obtained real server IP information with the displaying server IP information; and determining an active domain name to be tested as a valid active domain name if the obtained real server IP belongs to the local server IP and the displaying server IP belongs to the real server IP. By means of the method provided by the invention, the validity of the active domain names is judged, and invalid domain names, domain names which do not correspond to the displaying server IP address but can be accessed and domain names which do not belong to the local IDC computer room can be effectively filtered out, therefore, the authenticity and accuracy of the active domain names can be furthest insured.

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 an active domain name in an IDC computer room. Background technique [0002] The Internet Data Center (“IDC” for short) is an enterprise model specialized in providing network resource outsourcing and professional network services, which is an inevitable result of a more refined 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 telecom management departments. [0003] Information security management includes active resource monitoring and management, illegal website management, and illegal information monitoring an...

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
