Abstract

The invention provides a method for protecting a file system, which comprises the following steps of: when monitoring that a non-system application in an intelligent terminal initiates an operation request for the file system, judging whether an access area corresponding to the operation request is a system file area pre-divided by the file system or not; if the operation request is the system file area, judging whether the operation request is a request for executing a write operation on a write forbidding sub-area preset in the system file area or not; if yes, the operation request is intercepted, and if yes, the operation request is requested to execute the write operation on the write forbidding sub-region; and obtaining initiation record information of the operation request, and transferring the non-system application to a target supervision area determined based on the initiation record information according to a preset isolation rule so as to perform data supervision on the non-system application. The invention further provides a file system protection system, a storage medium and computer equipment. Therefore, the file system can be prevented from being damaged, and the safety of the intelligent terminal is improved.

Description

technical field [0001] The present invention relates to the technical field of terminal security, and in particular, to a file system protection method, system, storage medium and computer equipment. Background technique [0002] The file system is a software organization responsible for managing and storing file information in the operating system of the smart terminal. Therefore, how to improve the security of the file system is the primary privacy security issue to be solved by the smart terminal. [0003] The traditional technical solution provides an Android malicious application detection method based on dynamic monitoring of file access. By modifying the Android kernel source code, the application can output a corresponding file access information list when running on an Android phone, and compare the list with the policy set. The final judgment is whether the sensitive behavior is triggered, and then whether it is a malicious application. So as to monitor the modifi...
