Abstract

The embodiment of the present invention discloses a method and device for detecting the security of a Domain Name System (DNS) server, which is applied to an electronic device through which a mobile terminal is connected to a network. The method includes: obtaining an identifier of a webpage to be accessed sent by the mobile terminal, Send a domain name resolution command to the configured DNS server of the mobile terminal and the selected public DNS server, receive the resolution results fed back by the configured DNS server of the mobile terminal and the selected public DNS server, and based on the feedback from the configured DNS server of the mobile terminal Whether the network address is consistent with the network address fed back by the selected shared DNS server generates a detection result for the security of the configured DNS server of the mobile terminal. By applying the embodiment of the present invention, the security of the DNS server can be detected, and then the security of the mobile terminal can be detected.

Description

technical field [0001] The invention relates to the field of DNS servers, in particular to a method and device for detecting the security of a domain name system DNS server. Background technique [0002] At present, electronic devices such as computers and notebook computers are often equipped with wireless local area network sharing software. When the electronic device starts this type of wireless local area network sharing software, other mobile terminals can be connected to the electronic device. [0003] When a mobile terminal connected to a certain electronic device needs to access a web page, the mobile terminal sends the identification of the web page to the configured DNS (Domain Name System, Domain Name System) server of the mobile terminal through the electronic device, and receives the The DNS server resolves the obtained network address according to the identifier of the webpage, and accesses the webpage according to the network address. It can be seen that when...
