CYBER SECURITY ANALYSIS METHOD AND APPARATUS OF DIGITAL CONTROL SYSTEMS IN NUCLEAR POWER PLANT

摘要

PURPOSE: A method and apparatus for managing the cyber security of a digital measurement control system in a nuclear power plant are provided to protect digital asset against cyber risk according to a system design process, a detail design process, and an operation evaluating process of the digital measurement control system. CONSTITUTION: An apparatus for managing a cyber security includes an evaluating unit(510), a diagnosing unit(520), and a managing unit(530). The evaluating unit analyzes a cyber security requirement, a cyber security target/asset, a cyber security risk and a cyber security weakness, and evaluates a cyber security level. The diagnosing unit models a detain design weakness and analyzes a development environment. The diagnosing unit diagnoses a source, a network scan, a system weakness, or a maintenance and repair policy. The managing unit manages a development process and security data.
