A security device includes an attack detection part, a security risk state determination part, and an execution environment controller. The attack detection part detects a cyber attack on an embedded device controlled by an embedded control device. The security risk state determination part determines a security risk state indicating at least one of a type and degree of risk of threat in a security caused by the cyber attack based on a result of the detection. The execution environment controller is included in the embedded control device, determines a security function against the cyber attack in accordance with the security risk state, and constitutes an execution environment of the security function in the embedded control device so that the embedded control device can execute the security function.

Security device and embedded device

A control device including a failure diagnosis unit configured to identify a phenomenon that is a cause of the detected error, wherein the failure diagnosis unit is configured to: calculate a diagnosable time available to be spent on the identification of the phenomenon that is the cause of the error; and identify, for each detected error, a phenomenon that is the cause of the error based on a posterior probability, which is calculated for each phenomenon that is likely to be the cause of the error as a probability of occurrence of the phenomenon, on a diagnosis time, which is obtained for each phenomenon as a period of time required to identify the phenomenon as the cause of the error, and on the diagnosable time.

Control device, and processing method in event of failure in control device

A moving object controlling device () determines, when malfunction of an instrument such as a processor () mounted in a moving object () is specified, control contents with respect to the moving object () according to malfunction contents such as a level of the specified malfunction and a peripheral situation of the moving object () such as a movement place of the moving object () and a movement environment that influences movement of the moving object (). Then, the moving object controlling device () controls the moving object () according to the determined control contents.

Moving object controlling device, moving object controlling method, and computer readable medium

An information apparatus includes: a device to operate according to plural pieces of setting information by plural initialization processings; and a processor including a first control unit to execute, on basic software, first software performing processing using the device, and a second control unit to execute second software that operates the device using part of the setting information by the plural initialization processings and performs processing using the device at a stage when part of the plural initialization processings is completed and before the first software is executed, and performing the plural initialization processings for the device.
