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, wherein the dynamic configuration information comprises a main primary domain name resolution system DNS server address; switching a dynamic configuration networking state to a static networking state, wherein the dynamic configuration networking state is a state of receiving the dynamic configuration information sent by the DHCP device and accessing the network based on the dynamic configuration information, the static networking state is a state of accessing the network according to static secure configuration information, and the main DNS server address of the secure configuration information is a 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...
