Abstract: An apparatus for quantifying the security of an open-source software package and an apparatus and method for optimizing an open-source software package. The apparatus for optimizing an open-source software package includes a deletion target selection unit for creating a deletion target package list, which is a list of packages to be deleted from the total list of packages installed in a client, a package test unit for controlling the states of one or more virtual machines included in the client and receiving the result of performing a test case to which the deletion target package list is applied from the client, and a package optimization unit for creating an optimized package list based on the result of performing the test case.

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: A method for providing a browser using browser processes separated based on access privileges and an apparatus using the method. The method includes acquiring a first address corresponding to a first webpage; acquiring a first set of terminal access privileges based on the first address from a privilege control list and executing a first browser process corresponding to the first set of terminal access privileges; determining whether to allow rendering by comparing the first set of terminal access privileges with a second set of terminal access privileges corresponding to a second webpage when the first browser process attempts to render the second webpage; and if the rendering is not allowed, blocking the first browser process from rendering and rendering the second webpage by executing a second browser process corresponding to the second set of terminal access privileges.
