Abstract

In an information processing apparatus, a computer includes plural communication interface means corresponding to networks different from each other, a routing means for selecting communication interface means corresponding to a communication request issued by a task from a routing table in which the relation between destinations of communication and communication interface means to be used in the communication is prescribed, a task table update means for recording a combination of a task and communication interface means used in a first communication carried out by the task to a task table and deleting a record as to the task from the task table when the task is finished, and a communication interface restriction means for permitting the communication when the selection carried out by the routing means corresponds to the task table and shutting off the communication when the selection does not correspond to the task table.

Description

technical field [0001] The present invention relates to an information processing device, a communication control method, and a communication control program, and more particularly, to a technique for preventing information leakage in an information processing device having a plurality of communication interfaces. Background technique [0002] In recent years, as information networks typified by the Internet and corporate networks have gradually spread widely, such information networks are required to be reliable as social infrastructure. In particular, from the viewpoint of security (such as protection of personal information, etc.), there is an increasing need for a communication control technology capable of preventing information leakage. [0003] In a traditional information network, devices connected to multiple information networks are limited to relay devices, such as switches and routers. Because these devices are under the control of the information network admini...
