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 a method for establishing a remote work environment for ensuring the security of a user terminal for remote work and an apparatus using the method. The method, performed by the apparatus, includes acquiring media image creation information from a user; creating a certificate for VPN access based on the media image creation information and creating a media image using the media image creation information and the certificate for VPN access; and providing the media image to the user such that the user is able to create a medium for remote work. The user terminal for remote work is booted through the medium for remote work, thereby configuring a runtime environment for remote work in which security is ensured.

Abstract: Disclosed herein are an apparatus and method for preventing a security threat to a virtual machine. 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 is configured such that a hypervisor for virtualization in a host kernel executes a virtualization instruction corresponding to the service requested by a virtual machine of a host application and such that a hypervisor for monitoring interrupts the virtualization instruction in response to a security threat event occurring in the monitoring area of the hypervisor for virtualization and controls the process and thread of the host kernel. The hypervisor for monitoring is located in an area separate from the area in which the hypervisor for virtualization is located in the host kernel.
