APPARATUS AND METHOD FOR PREEMPTIVELY PROTECTING AGAINST MALICIOUS CODE BY SELECTIVE VIRTUALIZATION

摘要

An apparatus for preemptively protecting against malicious code by selective virtualization comprises: a compulsory resource storage unit which selects and stores compulsory resources required for executing a vulnerable program having an interface with an external source in a separated space; a modified resource-generating unit which generates a new resource by modifying the content of a resource accessed by the vulnerable program in the event the vulnerable program accesses a resource other than said compulsory resources; and a resource control unit which performs an operating system-level virtualization when the vulnerable program accesses the compulsory resource, and permits the vulnerable program to access the modified resource when the vulnerable program accesses a resource other than the compulsory resource.
