AI Technical Summary
Technical Problem
Existing Cyber Physical Systems (CPS) that integrate control equipment do not adequately consider both security and availability, leading to potential failures and risks in real-world operations.
Method used
An analytical apparatus comprising a first detection unit for simulated attacks, a second detection unit for availability evaluation, and an overall evaluation unit to generate comprehensive security and availability results, ensuring both aspects are considered in system operations.
Benefits of technology
Provides a CPS that balances security and availability, preventing failures and ensuring safe, reliable operation of control equipment.

Abstract
To provide a CPS having both the availability and the security taken into consideration.SOLUTION: An analyzing device includes: a first detecting unit that detects a simulation attack result from a simulation result in which a predetermined security countermeasure is applied to an evaluation subjected model obtained by modeling an evaluation subject, and then a simulation attack is given thereto; a second detecting unit that detects an availability evaluation result representing whether the simulation result is in compliance with evaluation conditions relating to the availability of the evaluation subject or not; and a comprehensively evaluating unit that generates the comprehensive evaluation results of the security countermeasure and the availability both subjected to the evaluation on the basis of the simulation attack result detected by the first detecting unit and of the availability evaluation result detected by the second detecting unit.SELECTED DRAWING: Figure 1
