Computer and user management method in virtual environment

Abstract

The invention provides a user management device and a method in a virtual environment. The computer comprises a hardware platform, a virtual machine manager, a first operation unit, a second operation unit, a second operation system installed on the virtual machine manager and a virtual machine operation management unit, wherein the first operation unit comprises a management unit for setting a plurality of users and distributing corresponding resources and authorities for each of the plurality of users; and the virtual machine operation management unit is used for collecting the resources and the authorities corresponding to each of the plurality of users, transmitting a first user in the plurality of users, the resources and the authorities corresponding to the first user to the second operation system, acquiring read / write operation requests of the first user on resources corresponding to the first user according to the authorities corresponding to the first user, and returning corresponding read / write operation results to the second operation system through the virtual machine manager. The method avoids a condition that the first user uses resources of other users over the authority of the first user.

Description

technical field [0001] The invention relates to computer system user management in the computer field, in particular to a user management method in computers and virtual environments. Background technique [0002] Today's personal computers all support multi-user and multi-tasking operating systems. Generally, there is a default super user in the computer, who can create other users and grant them certain permissions. Other users created by superusers have different computer resources and operation permissions due to different roles; however, superusers or users authorized by superusers can see and operate all computer resources. [0003] Under normal circumstances, this kind of user rights management scheme can well realize the management of computer user resources. In the Internet age, under the attack and destruction of hackers and viruses, it often happens that low-level users obtain superuser authority and control of all computer resources by running programs with loo...

Problems solved by technology

[0008] In a multi-user, multi-tasking computer system, since multiple users operate on resources in the same operating system, users with top-level privileges can operate all computer resources, so users with low privileges can run certain The software obtains the authority of the user with the top authority and the control of all computer resources, thereby causing information leakage or data destruction
