Safety management system for virtual machine and computer terminal

Abstract

The invention discloses a safety management system for a virtual machine and a computer terminal, belonging to the technical field of operation systems. The system comprises a first operation unit and a second operation unit; the first operation unit is connected to the second operation unit; the first operation unit is used for operating the virtual machine; the second operation unit is used for operating a host operation and also used for creating and deleting the virtual machine; the system further comprises a first storage unit and a storage rewriting unit, wherein the first storage unit is a magnetic disk of the virtual machine and stored with system data related to the virtual machine; and the storage rewriting unit is used for filling the storage space of the first storage unit through a preset character before the second operation unit creates the virtual machine or after the second operation unit deletes the virtual machine. The technical scheme provided by the invention has the benefits that: safety protection of the virtual machine in each operation state can be ensured; and privacy data are prevented from being illegally copied or optionally tampered.

Description

technical field [0001] The invention relates to the technical field of operating systems, in particular to a virtual machine security management system and a computer terminal. Background technique [0002] Existing virtual machine images are usually stored in external storage devices in the form of disk files. Therefore, although the virtual machine will be protected by the file access rights of the host operating system during operation and cannot be accessed by ordinary users at will, but When the external storage device is mounted on other operating systems, the access to the virtual machine image file will no longer be restricted by the original host system, but can be accessed by any user, thus making the tenant's private data There is a risk of leakage. Contents of the invention [0003] According to the above-mentioned problems existing in the prior art, a technical solution of a virtual machine security management system and a computer terminal is now provided, a...
