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

Claim 7:
8. An information processing apparatus connected to a communication control device via a network, comprising:
an attack detector that detects an unauthorized attack;
a detection information notifier that transmits attack detection information concerning the detected unauthorized attack to the communication control device;
a countermeasure instruction information acquirer that acquires attack countermeasure instruction information transmitted from the communication control device;
a countermeasure instruction determiner that determines a countermeasure method to be executed against the detected unauthorized attack from the acquired attack countermeasure instruction information; and
an attack countermeasure executor that executes the determined countermeasure method against the detected unauthorized attack, wherein
after the attack detector detects the unauthorized attack, the detection information notifier transmits the attack detection information concerning the detected unauthorized attack to the communication control device,
when the attack countermeasure instruction information including the countermeasure method against the detected unauthorized attack determined from an attack countermeasure instruction associated with the attack detection information and an attack countermeasure function for the information processing apparatus which transmitted the attack detection information stored in advance, in the communication control device is transmitted from the communication control device, the countermeasure instruction information acquirer acquires the transmitted attack countermeasure instruction information, and
when the information processing apparatus acquires the attack countermeasure instruction information, the determined countermeasure method against the detected unauthorized attack indicated in the acquired attack countermeasure instruction information is executed.
