Information processing device and information processing method

An information processing device for managing a plurality of information security functions related to information security of a vehicle, and an information processing function related to predetermined information processing, comprising:

• a processor that is configured to perform control processing for realizing the plurality of information security functions including a virus detection/removal function and an encryption function, and configured to perform control processing for realizing the information processing function;
• and
• a storage unit that is communicatively coupled with the processor and that stores information related to the information security function and the information processing function, wherein:
• the processor is configured to manage the information security function, and manage the information processing function;
• the storage unit stores operation management information comprising one or more events related to the information processing function, an operation content, of the information security function and an operation content of the information processing function comprising a plurality of security levels, each security level defining whether or not each of the virus detection/removal function and the encryption function is currently valid or invalid;
• and
• the processor is configured to:
• detect an occurrence of the one or more events related to the information processing function, including detection of one or more external devices currently connected to the information processing device,
• determine the operation content of the information security function based on the event, the occurrence of which is detected, and the operation management information stored in the storage unit,
• determine the operation content of the information processing function based on an operation result of the information security function according to the determined operation content of the information security function and the operation management information by determining which one of a plurality of security levels to set as a current security level according to a number of external devices determined to be connected to the information processing device, and
• manage the information processing function based on the determined operation content of the information processing function by setting the determined one security level as the current security level.

An information processing method to be performed by an information processing device for managing a plurality of information security functions related to information security of a vehicle, and an information processing function related to predetermined information processing, wherein:

• the information processing device comprises:
• a processor that is configured to perform control processing for realizing the plurality of information security functions including a virus detection/removal function and an encryption function, and configured to perform control processing for realizing the information processing function, and
• a storage unit that is communicatively coupled with the processor and that stores information related to the information security function and the information processing function;
• the storage unit stores operation management information comprising one or more events related to the information security function, a state of the information processing function, and the operation content of the information security function comprising a plurality of security levels, each security level defining whether or not each of the virus detection/removal function and the encryption function is currently valid or invalid;
• the processor is configured to:
• detect an occurrence of the one or more events related to the information security function, including detection of one or more external devices currently connected to the information processing device,
• acquire a plurality of kinds of information related to a state of a system in which the information processing device is installed,
• determine the state of the information processing function based on a combination of the acquired plurality of kinds of information,
• determine which one of a plurality of security levels to set as a current security level according to a number of external devices determined to be connected to the information processing device, the determined state of the information processing function, and the operation management information stored in the storage unit, and
• manage the security function based on the determined operation content of the information security function by setting the determined one security level as the current security level.
