Abstract

The invention provides a method and apparatus for reducing a DNS hijacking risk. The method comprises the following steps: sending a dynamic configuration request to a dynamic host configuration protocol DHCP device in a local area network; receiving dynamic configuration information returned by the DHCP device, wherein the dynamic configuration information comprises an internet protocol IP address of user equipment UE; sending the IP address of the UE to a security server; receiving a candidate wide area network DNS server address of a candidate wide area network DNS server, which belongs to the same operator as the UE, is determined by the security server on the basis of the IP address of the UE and is sent by the security server; determining the candidate wide area network DNS server address as a target wide area network DNS server address; switching a dynamic configuration networking state to a static networking state, wherein the main DNS server address of the secure configuration information is the target wide area network DNS server address; and accessing the network based on the secure configuration information.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method and device for reducing the risk of DNS hijacking. Background technique [0002] A common LAN DNS (Domain Name System, Domain Name System) hijacking is that the attacker builds a malicious fake DNS server in the LAN, and invades the DHCP (Dynamic Host Configuration Protocol, Dynamic Host Configuration Protocol) of the LAN The device modifies the DNS server address assigned by the DHCP device to the UE (User Equipment, User Equipment) to a pseudo DNS server address. Then, if the UE connects to the fake DNS server based on the network configuration dynamically assigned by DHCP, there is a risk of hijacking. Contents of the invention [0003] In view of the above problems, the present invention is proposed to provide a method and device for reducing the risk of DNS hijacking to overcome the above problems or at least partially solve the above problems. [0004] In t...
