Abstract: A data acquisition unit (21) acquires operation data including an influence-source object being an object which has performed an operation to influence another object, an influence-destination object being an object influenced by the operation performed by the influence-source object, and an attack probability representing a probability of the operation being an attack. A relation construction unit (22) constructs relation data when the attack probability is equal to or higher than a threshold value A, by adding a relation between the influence-source object and the influence-destination object to relation data. When an attack is detected, a specification unit (23) specifies at least either of an infected range supposed to be affected by the attack, and an intrusion route of the attack, based on the relation data.

Abstract: An information processing apparatus (100) includes a validity verification unit (101). The validity verification unit (101) verifies validity of startup software by comparing verification subject data which is data for verification calculated based on data stored in a storage place indicated in startup record data indicating the storage place where the startup software executed at startup of the information processing apparatus (100) is to be stored, and which is data for verification calculated at the startup of the information processing apparatus (100), with comparison data which is data for verification calculated before the startup of the information processing apparatus (100) based on the startup software, and which is data for verification used as a comparison subject of the verification subject data.

Abstract: An on-vehicle control apparatus (130) switches an operating state of an on-vehicle control system (100) from a regular state to a partially checking state in a case where a cyber-attack has been detected in a part of a plurality of driving control apparatuses (110 and 120). The regular state is an operating state in which autonomous driving is performed by using at least one of the plurality of driving control apparatuses. The partially checking state is an operating state in which the autonomous driving is performed by using at least one of normal driving control apparatuses where the cyber-attack has not been detected, and security of each of the driving control apparatuses where the cyber-attack has been detected is checked.

Abstract: A execution monitoring device (20) includes a time-series data storage unit (225) to store time-series data and a real-time specification determining unit (204). The real-time specification determining unit (204) updates a determination result, which is a result of determining whether the time-series data stored in the time-series data storage unit (225) satisfies a real-time specification, which is part of constraints included in a monitoring specification for electronic device runtime monitoring, is stored in a memory area reserved before execution of the real-time specification determining unit (204), and is a constraint using a real time.

Abstract: A communication apparatus 1 is provided with a first communication interface 11, second communication interfaces 12 connected to a plurality of access routers 3 connected to an Internet 6, and a route determination unit which, for a packet being communicated from the first communication interface 11 to the second communication interfaces 12, determines the second communication interface 12 in accordance with an elapsed time since connecting start of a connection with a destination of the packet. Connections having started within a predetermined time are treated as connections constituting one user session. Therefore, connections constituting the same user session can be communicated via the same access router without the need of analyzing a protocol of a layer.

Abstract: In a wireless information distribution apparatus, a transmission unit transmits radio waves for distributing information. An adjustment unit acquires first data indicating a degree in which a person is present around the wireless information distribution apparatus. Moreover, the adjustment unit acquires second data serving as an index of a possibility that another apparatus that distributes information by radio waves is present around the wireless information distribution apparatus. The adjustment unit adjusts, based on the first data and the second data, the intensity of the radio waves to be transmitted by the transmission unit.

Abstract: An in-vehicle apparatus that is a radio communication apparatus includes: a radio communication unit capable of performing radio communication using at least a 5-GHz band; a present-position detecting unit that detects a present position of the own apparatus; and a radio-communication-zone predicting unit that determines, when the radio communication unit is performing communication, whether switching of a channel of the radio communication unit is necessary on a basis of interference data, which is information concerning a coverage of a radio wave transmitted from another system that uses a 5-GHz band and transmits and receives a radio wave in a stationary state, map data, and the present position detected by the present-position detecting unit, and, when switching is necessary, further selects a switching destination channel or causes the radio communication unit to select the switching destination channel.
