Patent ID: 11930035
Assignee: SHARP KABUSHIKI KAISHA
Field: Digital communication (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 4:
5. The communication control system according to claim 1, wherein the communication control device further includes a pseudo-attack diagnosis section that performs a diagnosis on the detected unauthorized attack by pseudo-executing an attack similar to the detected unauthorized attack detected in the information processing apparatus to a second information processing apparatus other than the information processing apparatus which detected the unauthorized attack,
the attack countermeasure information further includes a pseudo-attack diagnosis in which a pseudo-executed attack content and a diagnosis result in the case of the attack are set in advance, and the attack countermeasure information including the attack countermeasure instruction associated with the attack detection content, the attack countermeasure function, and the pseudo-attack diagnosis and indicating the countermeasure method to be executed against the predicted attack of the attack detection content is stored in advance,
after the attack detection information is acquired from the information processing apparatus which detected the unauthorized attack, the pseudo-attack diagnosis section performs the diagnosis by pseudo-executing the attack similar to the detected unauthorized attack against the second information processing apparatus,
the attack countermeasure decider selects the attack countermeasure instruction associated with the attack detection content that matches the attack detection information, the attack countermeasure function for the second information processing apparatus, and the pseudo-attack diagnosis that matches the diagnosis generated by the pseudo-attack diagnosis section by using the attack detection information acquired from the information processing apparatus and the attack countermeasure information and determines the countermeasure method to be executed against the detected unauthorized attack, and
the countermeasure instruction information generator generates second attack countermeasure instruction information including the determined countermeasure method and transmits the second attack countermeasure instruction information to the second information processing apparatus.
