DIGITAL ASSETS ANALYSIS METHOD OF INSTRUMENTATION AND CONTROL SYSTEM IN NUCLEAR POWER PLANT AND APPARATUS THEREOF

摘要

The present specification relates to a digital assets analysis method of a digital instrumentation and control system in a nuclear power plant, capable of performing a cyber security evaluation of the nuclear power plant applied by a digitalized apparatus and an apparatus thereof. The digital assets analysis apparatus of a digital instrumentation and control system in the nuclear power plant in accordance with an embodiment of the present invention can comprise: a digital assets modeling module which places the digital assets of the digital instrumentation and control system in the nuclear power plant on a display unit, connects a network among the digital assets, and sets a predetermined security grade for each of the digital assets; and a diagnosis unit which identifies the digital assets violated by a predetermined security guideline of the digital assets based on an attribute value of the digital assets and on an attribute value of the network, generates a security check list including a violated security item of the identified digital assets, and displays the generated security check list on the display unit.
