Abstract

The invention provides a VPN (Virtual Private Network) connection method based on a blacklist mechanism. The method comprises the following steps: when a request instruction of establishing VPN connection is received, acquiring feature information of a client performing VPN connection, wherein the feature information includes an IP address, a digital certificate summary, a user name and a password; judging whether the IP address, the digital certificate summary and the user name conform to corresponding information in a blacklist or not in sequence; if one of the IP address, the digital certificate summary and the user name conforms to the corresponding information in the blacklist, rejecting the VPN connection; and if all the IP address, the digital certificate summary and the user name do not conform to the corresponding information in the blacklist, and the digital certificate summary and the password are matched with a preset digital certificate summary and a preset password respectively, establishing the VPN connection. Through combination of VPN verification and the blacklist mechanism, hacker behaviors such as flooding attacks and brute force attacks can be prevented effectively.

Description

technical field [0001] The present application relates to the field of VPN connection, in particular to a method and system for VPN connection based on a blacklist mechanism. Background technique [0002] With the development of technology, people pay more and more attention to the VPN connection method. [0003] Existing VPN servers only provide connection services, and are helpless against flooding attacks by hackers and password probing. [0004] Therefore, how to effectively prevent flooding attacks, brute force cracking and other hacking activities when performing a VPN connection is a technical problem to be solved by those skilled in the art. Contents of the invention [0005] The technical problem to be solved in this application is to provide a VPN connection method and system based on a blacklist mechanism, which solves the problem in the prior art that VPN servers only provide connection services and are helpless against flooding attacks by hackers and password...
