Safe dns system and dns safe parsing method based on local parsing

Abstract

The invention relates to a local resolution-based secure DNS system and a DNS security resolution method. The system includes a client module and a server module. The client module is deployed on the user's own host, and the server module is deployed by the solution provider. The client module and the server module communicate through a private encryption protocol. The client module includes: an encrypted communication module, a fixed data module, an updateable data module, and an update policy module; the server-side module includes: an encrypted communication module, a data collection module, a data processing module, a data delivery module, and task scheduling module. The present invention provides a DNS security analysis solution that can be quickly implemented by ordinary users. Users can complete the improvement of security levels through autonomous deployment without waiting for network providers to deploy security devices on a large scale, thereby controlling security issues in the hands of users themselves.

Description

technical field [0001] The invention belongs to the field of network technology and DNS technology, and in particular relates to a local resolution-based secure DNS system and a DNS security resolution method. Background technique [0002] When the Internet first appeared, the scale of the network was relatively small, and the communication between hosts directly used IP addresses. With the development of the network scale, it was very inconvenient to use IP addresses directly. The industry gradually used the mapping between host names and IPs to solve this problem. Question, through the host name, the process of finally obtaining the IP address corresponding to the host name is called domain name resolution. The earliest domain name resolution relied on querying the local file (host file) to obtain the mapping relationship. Each host maintained its own host file. After the network scale increased exponentially, due to the limitations of the hardware and network at that time...
