Implementation method for implementing root-authority-free networking firewall and client-side

Abstract

The invention discloses an implementation method for implementing a root-authority-free networking firewall and a client-side. The method includes the steps of obtaining a network connection request; redirecting the network connection request to a local service process, wherein the local service process is provided by a local VPN service; obtaining the application name of the application triggering the network connection request by inquiring about a system file in the local service process; inquiring about a pre-configuration file to obtain the configuration strategy which is recorded in the pre-configuration file and corresponds to the application name; processing the network connection request according to the configuration strategy. Due to the fact that the application in the VPN frame is allowed in the operating system to have the higher control right for network connection, by means of the VPN frame, control over network connection of other applications can be achieved through the application without obtaining the root authority.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a method for implementing a networked firewall without root authority and a client. Background technique [0002] With the popularity of smart phones and the development of mobile Internet technology, mobile Internet access has become an indispensable requirement for "mobile Internet users", and there are more and more applications on smart phones. Compared with PCs, mobile phones are highly private, and mobile phone security risks pose a greater threat to users. Some mobile phone rogue software, mobile phone hackers, mobile phone data theft and other security problems lead to unreasonable expenses and other forms of losses for users. [0003] In order to strengthen the security of mobile Internet access, the existing technology provides network firewall technology. Users can use network firewall to set application program Internet access rules, block and allow application p...

AI Technical Summary

Problems solved by technology

However, due to the limitation of the authority of the mobile phone operating system, the existing networked firewall must obtain the root authority to realize the above functions, and then manage and control other application programs according to the obtained root authority

However, to obtain root authority needs to be realized by flashing the machine. For the realization of the above functions, since the refresh of the system files needs a certain delay, the networked firewalls of the prior art generally have the problem of delayed feedback results.
