Abstract:
A communication security apparatus includes a communicator that receives a packet from a first device and transmits the received packet to a second device, a memory that retains address authentication information containing pairs of a physical address and a logical address of one or more devices, and a controller. After a learning period of receiving and transmitting packets, the controller determines whether a pair of a physical address and a logical address of the first device and the second device match any one of the pairs of the physical address and the logical address of the one or more devices in the packet, and discards the packet when the pair of the physical address and the logical address of the first device and the second device do not match any one of the pairs of the physical address and the logical address of the one or more devices.
Abstract:
A method in the disclosure includes: receiving, from an information device, a device password which is used for controlling a target device via an in-house server apparatus and which is input on the information device using a setting screen; managing a device ID of the in-house server apparatus, a user ID, and the device password in association with one another; transmitting the device password to the in-house server apparatus to cause the in-house server apparatus to manage the device ID and the device password; transmitting, when login to an out-of-house server apparatus is authenticated, an authentication screen to the information device; receiving, from the information device, an input password that is input on the information device using the authentication screen; and when the received input password is identical to the device password that is associated with the user ID, approving a control of a target device by the information device.
Abstract:
Provided is an information acquisition method in an information acquisition system including an information device possessed by a user. A detecting step detects a specific action performed by the user while driving a motor vehicle. A first saving step acquires and saves, in a storage unit, motor vehicle position information indicating a position of the motor vehicle if the specific action is detected by the detecting step. A deleting step deletes the motor vehicle position information from the storage unit in a case in which the specific action is an action other than an action of speaking a voice phrase, and when a designated time elapses in a case in which the user does not perform an action of speaking a voice phrase from a time at which the specific action was detected and before the designated time elapses.

Abstract:
A secure hub as a communication security apparatus includes a port that receives a packet from a device and transmits the packet to another device. The secure hub also includes a storage area that retains address authentication information containing pairs of a physical address and a logical address of one or more devices. The secure hub further includes a transfer processing unit that determines whether the pair of the physical address and the logical address of the device, and the pair of the another device, each match any pair of the one or more devices when the address authentication information contains the physical address or the logical address of the device and the another device contained in the packet, and discards the packet when the pair of the device and the pair of the another device do not match any of the pairs of the one or more devices.
Abstract:
A network protection device includes a packet capture unit which captures a network packet through an intelligent switch which performs connection in a communication network or across communication networks; a network analyzer which detects a threat in the network packet; a threat remover which removes the threat in the network packet; and a switch operator which changes from a first communication path, which connects a sender node to a receiver node without the threat remover, to a second communication path, which is different from the first communication path and connects the sender node to the receiver node through the threat remover when the threat is detected in the threat detector.
Abstract:
An integration server manages production in a manufacturing line that includes a first stage and a second stage carried out after the first stage. The integration server includes a communicator that acquires a first production log and a second production log. The first production log includes a first production count of processing objects in the first stage. The second production log includes the number of processing objects in the second stage. The integration server also includes an irregularity detector that detects the presence of irregularity in the first production log and the second production log on the basis of the first production count and the number of the processing objects in the second stage.
