Traffic safety control method and system based on DPI and cloud synchronization

Abstract

The invention discloses a traffic safety control method and system based on DPI and cloud synchronization. The method comprises the following steps: using DPI technology to perform depth analysis on each packet that flows through a router, distinguishing malicious traffic and normal traffic, intercepting the malicious traffic, jumping a user to a prompt interface, and reminding the user that web pages to be accessed are harmful; and if the malicious traffic is the severe malicious traffic, then directly performing an interception operation, and prohibiting the severe malicious traffic to communicate with a client. The traffic safety control method based on the DPI and the cloud synchronization provided by the invention fully considers the diversity of security threats and the continuous development of private information stealing means, stores malicious links in the way of cloud storage, and updates a malicious linked database regularly; and meanwhile, the method also considers the present situation that the user is very lack of information security knowledge, and transfers the responsibility of the user privacy protection from the user itself to a public WiFi system, so as to realize the private information protection of the user technically.

Description

technical field [0001] The invention belongs to the technical field of computer network security, and in particular relates to a flow security control method and system based on DPI and cloud synchronization. Background technique [0002] With people's increasing dependence on smart phones and wireless networks, the public WiFi industry has ushered in the spring of its development, but compared with its rapid growth momentum, its security and monitoring are still at a very low level, and users' information Security awareness is relatively weak, which gives criminals an opportunity to take advantage of. [0003] There are three major safety hazards in free WIFI: first, the public WIFI set up by businesses does not have a basic online recording function, and cannot realize real-name Internet access. Once a cyber crime occurs, the perpetrator cannot be found, only the WIFI provider; The second is that the merchant’s password is too simple, and various management ports have not...

Problems solved by technology

[0003] There are three major safety hazards in free WIFI: first, the public WIFI set up by businesses does not have a basic online recording function, and cannot realize real-name Internet access. Once a cyber crime occurs, the perpetrator cannot be found, only the WIFI provider; The second is that the merchant’s password is too simple, and various management ports have not been closed. Once someone enters the main router, tampers with the DSN server information, etc., and hijacks the router; Shen, it only takes a few minutes to steal personal information and passwords on mobile phones, including online banking passwords, stock trading account passwords, credit card passwords, etc.
