Problems solved by technology

[0007] The above-mentioned first solution focuses on solving the intrusion event of the kernel state of the Linux system. The method of obtaining the call chain is to obtain the system call entry through the assembly instruction, and obtain the system call list pointer through the system call entry. The method is complicated and can only be applied to the Linux system; The second solution is to use the hook function to monitor the call of the loading function of the dynamic link library, and judge whether the loading function exists in the pre-stored malicious dynamic link library, thereby re...

Abstract

The invention discloses a security protection system and method for a call chain, and belongs to the technical field of call chain security protection. The system comprises: a call stack module which obtains a call chain, extracts process information of the call chain and transmits the process information to a call stack encryption module; a call stack encryption module which is used for receiving the process information and encrypting the process information in a preset mode; and a judgment processing module which is used for comparing the encrypted process information with encrypted data pre-stored in the encrypted file, and if the process data contains the process information, the process of the call chain is allowed to be loaded. According to the method, the event of illegally calling the process of the program is effectively prevented, an intrusion event is prevented, the safety of the program is guaranteed, and the method has very high application value.

Description

technical field [0001] The present invention relates to the technical field of call chain security protection, and more specifically, to a security protection system and method for call chains. Background technique [0002] With the continuous advancement of science and technology, in C# applications, there are many malicious calls of malicious software and illegal acts of destroying source programs, which have caused serious impact on society. [0003] Three existing technologies are introduced below, and existing problems are explained. [0004] In the patent application number 201310462793.4, an intrusion detection method and device are described, through the first acquisition module, the export module, the fingerprint algorithm processing module, the first comparison module and the first confirmation module, the kernel intrusion detection under the Linux system is realized . [0005] In the patent with application number 201510809215.2, a protection method and device f...
