Abstract: A method and apparatus for providing an operating system based on a lightweight hypervisor. An electronic device includes a hypervisor, an operating system monitor, and a virtualized operating system. The hypervisor enables the virtualized operating system and a physical machine to share the resources of the physical machine. If the virtualized operating system accesses the resource, the operating system monitor determines whether to allow the access to the resource. Also, the operating system monitor verifies the integrity of the virtualized operating system and determines whether a threat to the virtualized operating system exists.

Abstract: Disclosed herein are an apparatus and method for providing a remote work environment. The apparatus includes one or more processors and executable memory for storing at least one program executed by the one or more processors. The at least one program performs Virtual Private Network (VPN) authentication in response to a request for remote access to a work network from a user terminal, performs user authentication in order to connect the user terminal that succeeds in VPN authentication to the work network, decrypts the encrypted user data area of the user terminal that is connected to the work network, and provides the remote work environment to the user terminal based on the user data area through the work network.
