Abstract: An update management apparatus and an update verification apparatus and method of a control system. The update verification apparatus of the control system includes a file type classification unit for classifying one or more input update files into any one file type of a firmware file, a patch file, and another type of file; an integrity verification unit for verifying integrity of the update files based on the file types of the update files; and an update file generation unit for generating a final update file from the update files, the integrity of which has been verified.

Abstract: A method and apparatus for quantifying the vulnerability of a system. The apparatus includes a vulnerability calculation unit, a target organization security level calculation unit, a network separation status calculation unit, an interim calculation unit, and a final score calculation unit. The vulnerability calculation unit converts each of the vulnerability identification results of the system into a vulnerability score. The target organization security level calculation unit calculates a target organization security level score based on a technology-field security level score and a management-field security level score. The network separation status calculation unit converts the status of the separation of the local network of the system into a network separation score. The interim calculation unit calculates an interim score. The final score calculation unit quantifies the vulnerability of the system by finally calculating a composite score using the interim score and a simulated intrusion success level.
