Abstract

Embodiments of the present invention provide a method and apparatus for reducing the risk of DNS hijacking. The method includes: 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, where the dynamic configuration information includes an Internet Protocol IP address of a user equipment UE; Send the IP address of the UE to the security server; receive the alternative wide area network DNS server address of the alternative wide area network DNS server belonging to the same operator as the UE determined and sent by the security server based on the IP address of the UE; The alternative wide area network DNS server address is determined as the target wide area network DNS server address; The dynamic configuration Internet access state is switched to the static Internet access state; The main DNS server address of the security configuration information is the target wide area network DNS server address; Based on the security configuration Information access network.

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...
