Risk detection method and system, electronic equipment and storage medium

The invention discloses a risk detection method and system, electronic equipment and a storage medium. The method comprises the steps of obtaining a disk snapshot of a mounted disk on a host instance; and performing risk detection on the host instance based on the disk snapshot to obtain a risk detection report. According to the embodiment of the invention, the disk snapshot of the host instance is obtained at the cloud, and the disk snapshot records all files of the instance at the current moment, so that the cloud can perform risk detection on all the files of the host instance based on the disk snapshot to generate the risk detection report so as to effectively discover instance risks. For a host instance, only a disk snapshot needs to be created, creation of the snapshot occupies a small amount of resources of the instance, normal operation of the instance is basically not affected, and detection operation needing to occupy a large amount of computing resources is transferred to a cloud end with unlimited
