Abstract

The present invention provides a method, device, and electronic device for monitoring abnormal requests from unknown programs, wherein the method includes: using the microfilter driver of the file system to monitor whether the target request is received at the driver layer of the terminal device, wherein the target request It is used to request to open a file; when the target request is monitored, the microfilter driver is used to judge whether the target request is an unknown program requesting to read or write to the disk according to the requested file object and the device object corresponding to the file object; when the target request is not In the case of an unknown program requesting the behavior of reading and writing to the disk, the target request is allowed to be executed; in the case that the target request is an unknown program requesting the behavior of reading and writing the disk, the target request is intercepted. The present invention solves the problem that the file-level monitoring method in the related art cannot prevent malicious programs from directly reading and writing disks.

Description

technical field [0001] The invention relates to the field of computer security protection, in particular to a method, device and electronic device for monitoring abnormal requests of unknown programs. Background technique [0002] With the increasing popularity of the Internet, people rely more and more on computers to handle various affairs, and it is more and more important to protect the security of the computer's operating system. Some malicious programs may implant some virus codes in the system by directly reading and writing the disk, especially for the operation of the system start sector MBR (Master boot record). Plant rootkits. For this kind of malicious program, file-level monitoring cannot capture it, because the direct read and write of the disk will skip the file level to read and write. [0003] Aiming at the above-mentioned problems existing in related technologies, no effective solution has been found yet. Contents of the invention [0004] Embodiments ...
