Abstract: The purpose of the present invention is to provide a technology which assists a verifying party in ascertaining an anomaly in an event of which notification has been made. Provided is an assistance device, comprising: an acquisition unit which acquires as an associated event, from among events which take place among a plurality of elements, and with respect to elements which have been associated with an event which has been detected as an anomalous event, an event other than the anomalous event which has been associated with the elements; and a generating unit which, on the basis of the anomalous event and the associated event, generates a relational graph in which the elements are vertices, the relations among the elements are edges, the anomalous event and the associated event are respectively represented, and the associated event is displayed in a display screen in a different manner from the manner in which the anomalous event is displayed.

Abstract: A first information processing apparatus (2000) determines an alternative representation (20) of an event sequence represented by a plurality of event histories (12), by use of dictionary data (30). The first information processing apparatus (2000) outputs information including the determined alternative representation (20). The dictionary data (30) indicate an event sequence and an alternative representation (20) relating to the event sequence in association with each other.

Abstract: Information regarding moving bodies (00) that are in danger of colliding is collected at an appropriate frequency in accordance with the degree of danger. This information-collecting device has a risk calculation unit and a transmission-interval determination unit. The risk calculation unit receives, from a plurality of moving bodies, state information that includes locations and velocities and is transmitted at provided time intervals. The risk calculation unit also computes the distance between and relative velocities of two moving bodies. The transmission-interval determination unit computes an interval such that the higher the relative velocities of two moving bodies are relative to the distance therebetween, the shorter the interval is, and provides the computed interval to the moving bodies.

Abstract: In an information processing device, a provision means provides multiple terminals with a common search model. A filter acquisition means acquires, from each terminal, a filter configured by a feature value obtained using the search model. A data acquisition means acquires, from each terminal, a target time series data subjected to state estimation. A estimation means estimates a state of the terminal which outputted the target time series data, based on the target time series data and the filter.

Abstract: Disclosed are a display control device, etc., with which information is displayed according to a display mode having high visibility. Provided is a display control device (101), comprising: a first identification information creation unit (103) with which a plurality of communication bodies which are capable of communication are classified into a plurality of groups, said unit creating first identification information which represents at least a portion of the communication bodies which are included in one of the groups; a second identification information creation unit (104) which creates second identification information which collectively represents a group set which represents two or more groups of the plurality of groups; and a control unit (102) which, on the basis of the size of a region which is displayed in a display means, selects specified identification information from the first identification information or the second identification information, and controls to display, in the display means, device identification information which represents the communication bodies which are not included in the specified identification information and/or the group identification information which represents the groups which are not included in the specified identification information, along with the specified identification information.

Abstract: A warning apparatus (2000) acquires first detected event information (10) representing, at a first abstraction level, an event set being a set of events having occurred in a target system. The warning apparatus (2000) generates second detected event information (20) from the first detected event information (10). The second detected event information (20) represents, at a second abstraction level, the event set represented by the first detected event information (10). The warning apparatus (2000) determines, from among a plurality of pieces of threat information (30) each representing a threat activity, the threat information (30) having a high degree of relevance to at least either of the first detected event information (10) and the second detected event information (20). The warning apparatus (2000) generates warning information (40) relating to a threat being occurring in the target system, based on the determined threat information (30) and a matching level being an abstraction level associated with the detected event information having a high degree of relevance to the threat information (30).

Abstract: An information processing apparatus 2000 executes analysis for an event history set (10). The event history set (10) is a set of a plurality of event histories (12). The event history (12) is information relating to an event generated in a target computer system. The information processing apparatus 2000 selects, based on a result of the analysis, an event history (12) to be excluded from deletion targets. The information processing apparatus (2000) deletes, from the event history set (10), an event history (12) other than the event history (12) excluded from the deletion targets.

Abstract: An information processing apparatus generates a graph that represents an action of a program. On the graph, an edge represents action contents of a process in an event. Further, two nodes connected by the edge respectively represent a subject and an object of the event. The information processing apparatus outputs the generated graph. Further, the information processing apparatus also alters the generated graph. When an index value of an event satisfies a first predetermined condition which index value is based on the number of occurrences or the frequency of occurrences of the event, the information processing apparatus alters the graph with respect to an edge representing the event.
