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

Claim 8:
9. A communication control method of a communication control system in which an information processing apparatus and a communication control device are connected to each other through a network, the communication control method comprising:
detecting, by the information processing apparatus, an unauthorized attack;
transmitting attack detection information concerning the detected unauthorized attack from the information processing apparatus to the communication control device;
storing attack countermeasure information, in advance, in the communication control device and the attack countermeasure information includes an attack detection content concerning a predicted attack, an attack countermeasure function which is a function held by the information processing apparatus in order to deal with the predicted attack, and an attack countermeasure instruction associated with the attack detection content and the attack countermeasure function and indicating a countermeasure method to be executed against the predicted attack of the attack detection content;
selecting the attack countermeasure instruction associated with the attack detection content that matches the attack detection information and the attack countermeasure function for the information processing apparatus which transmitted the attack detection information and determining a countermeasure method to be executed against the detected unauthorized attack by the communication control device;
generating attack countermeasure instruction information including the determined countermeasure method and transmitting the attack countermeasure instruction information to the information processing apparatus by the communication control device;
acquiring the attack countermeasure instruction information transmitted from the communication control device by the information processing apparatus;
determining the countermeasure method to be executed against the detected unauthorized attack from the acquired attack countermeasure instruction information by the information processing apparatus; and
executing the determined countermeasure method against the detected unauthorized attack by the information processing apparatus.
