Abstract: A data acquisition unit (21) acquires operation data including an influence-source object being an object which has performed an operation to influence another object, an influence-destination object being an object influenced by the operation performed by the influence-source object, and an attack probability representing a probability of the operation being an attack. A relation construction unit (22) constructs relation data when the attack probability is equal to or higher than a threshold value A, by adding a relation between the influence-source object and the influence-destination object to relation data. When an attack is detected, a specification unit (23) specifies at least either of an infected range supposed to be affected by the attack, and an intrusion route of the attack, based on the relation data.
