    Abstract: An information processing device includes: a memory; and at least one processor coupled to the memory. The processor performs operations. The operations include: extracting a transmission source of communication from communication data received by a predetermined device, and generating first data that include the transmission source and a time associated with communication and included in the communication data; and totaling a first frequency of reception of the communication data for the each transmission source, based on the first data, in each of a first period and a second period that includes the first period and is longer than the first period.

    Abstract: Provided is a log information generation apparatus and the like that generates log information where log of communication via a communication network are arranged in communication occurrence order. A log information generation apparatus provides time information including a second time in an information processing apparatus to a difference calculation apparatus in accordance with communication start information transmitted to a plurality of information processing apparatuses communicably connecting to a communication network at a start of communication processing via the communication network, the difference calculation apparatus calculating a difference between a input first time and a reference time; and generates log information associating arranged time with a content of communication processing, the arranged time obtained by arranging a time of the communication processing based on the difference calculated for the second time by the difference calculation apparatus.

    Abstract: Provided are a communication destination determination device and the like in which a communication destination that is highly likely to pose a threat can be detected. A communication destination determination device 101 is provided with: a signal transmission unit 102 which transmits, when a first signal transmitted from a communication destination 104 is received via a communication network, a second signal in response to the first signal to the communication destination 104; and a communication destination determination unit 103 which classifies whether the communication destination 104 is highly likely to pose a threat or not, on the basis of whether or not a third signal transmitted from the communication destination 104 is received within a certain time period from the timing of transmission of the second signal.
