Information processing apparatus, information processing method, configuration apparatus, and configuration method

An information processing apparatus comprising:

• computer hardware;
• system software that manages and controls the computer hardware;
• two or more application software items to be executed on the system software;
• an execution-environment separator/setter comprising
• an execution-environment-separation definition table where setting items of respective execution environments in which the application software items are executed are defined,
• a configuration-risk definition table where a risk of being intruded from the outside is defined for each of the execution environments,
• a configuration-risk evaluator that calculates a risk value for each of the execution environments, based on the configuration-risk definition table,
• an activation-setter that performs setting and activation processing of the respective execution environments for the application software items;
• and
• an execution-environment separator/deployer that deploys the execution environment on the computer hardware, in accordance with an instruction of the activation-setter and based on setting of the execution environment defined by the execution-environment-separation definition table, wherein the application software is executed in the execution environment deployed by the execution-environment separator/deployer.
