Safe DNS system based on local analysis and DNS security analysis method

Abstract

The invention relates to a safe DNS system based on local analysis and a DNS security analysis method. The system comprises a user side module and a server side module, the user side module is deployed in a host of a user, and the server side module is deployed in a provider of a solution; the user side module is in communication with the server side module through a private encryption protocol. The user side module includes an encryption communication module, a fixed data module, an updatable data module and a strategy updating module. The server side module includes an encryption communication module, a data collection module, a data processing module, a data issuing module and a task scheduling module. The DNS security analysis solution which can be achieved rapidly by the common user is provided, the user can promote the security level through independent deployment without waiting the network provider to deploy safety equipment on a large scale, and therefore safety problems are controlled by the user.

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...

Problems solved by technology

[0010] Aiming at the security problems existing in the current DNS resolution process, especially domain name hijacking and other problems, the present invention proposes a DNS security resolution solution that ordinary users can quickly realize, and users do not need to wait for network providers to deploy security devices on a large scale, and control security problems in the hands of the user
