Embodiment Construction

[0020] Hereinafter, exemplary embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0021] figure 1 Schematic diagram of WinSock framework, refer to figure 1 , The transport provider has two chains: TCP chain and UDP chain. There can also be other types of LSP chains.

[0022] In the TCP chain, there are 4 layers from top to bottom (the mswsock.dll at the bottom is a function of the operating system itself). The UDP chain includes 3 layers.

[0023] The three on the right are namespace provid...

Abstract

The invention discloses a registry redirecting method and device. The method comprises the following steps of: loading configuration information of an application program; judging whether layered service provider (LSP) configuration registry data comprises LSP dynamic link library (DLL) which needs to be shielded or not according to the loaded configuration information; if the LSP configuration registry data comprises the LSP DLL which needs to be shielded, deleting the information of the LSP DLL from the LSP configuration registry data to construct new LSP configuration registry data; and redirecting the operation of the LSP configuration registry data onto the newly constructed LSP configuration registry data. According to the method disclosed by the invention, through utilizing a registry redirecting mechanism, specific or all LSP DLLs are shielded by aiming at specific or all processes in a Windows system, and therefore, the LSP DLLs are prevented from being loaded into the processes, and the stability and the safety of the application program are improved.

Description

Technical field [0001] The invention relates to application program monitoring technology, in particular to a registry redirection method and device. Background technique [0002] LSP (Layered Service Provider) is a mechanism unique to WinSock (WinSock (Windows Sockets) is the abbreviation of the network communication architecture and specifications of the application layer of the Windows operating system provided by the operating system) of the communication architecture of the Windows platform. Through the extensible LSP mechanism, third-party software developers can insert DLL in the application to monitor and modify TCP / IP data packets, thereby developing rich network applications, such as chat software, communication encryption tools, network proxy software, Online game accelerator, etc. [0003] LSP can be used to develop formal applications. Virus and Trojan horse authors can also use LSP to insert malicious code into users' systems and steal user information. In addition,...
