Abstract
Provided are an apparatus and method of detecting and controlling a privilege level violation process. The apparatus monitors whether higher-privileged processes depend on information provided from lower-privileged objects or denies the higher-privileged processes to access the lower-privileged objects. The apparatus is provided in a process, and monitors whether a process accesses to a lower-privileged object. The apparatus gives a warning message or denies an access of the process to the lower-privileged object when it detects that the higher-privileged process access to the lower-privileged object. Therefore, the apparatus of detecting and controlling a privilege level violation process detects weaknesses that may be caused by privilege level violation, thus allowing a system to be safely operated.
