Abstract
An appropriate countermeasure is taken against a cyber-security attack at an appropriate timing. An analysis device, configured using a computer including a computation device that executes predetermined computation processing and a storage device accessible by the computation device, includes: a communication unit that receives, by the computation device, a log of an information processing device mounted on an instrument; an attack progress analysis unit that calculates, by the computation device, an intrusion location in a route from an intrusion point on the instrument to a protected asset from the received log; and an urgency degree determination unit that determines, by the computation device, an urgency degree of a countermeasure against an attack based on an analysis result of the attack progress analysis unit.
