Abstract: An information processing apparatus (2000) compares a name of a determination target file with a name of one or more normal files. The information processing apparatus (2000) outputs information related to the determination target file, when a name of the determination target file does not coincide with a name of any of the normal files, and a degree of reliability of the determination target file is equal to or less than a threshold value. A degree of reliability of the determination target file is calculated, based on a degree of similarity between a name of the determination target file and a name of each of the normal files.

Abstract: An information processing apparatus (2000) acquires an event graph (10) to be output and determines a subgraph satisfying a predetermined reference from the acquired event graph (10) to be output. In the event graph (10), an activity content in an event related to an activity of a program is represented as an edge (14), and each of a subject and an object of the event is represented as a node (12). The information processing apparatus (2000) outputs the event graph (10) with an output mode of the determined subgraph as a first mode and with an output mode of another portion as a mode other than the first mode. The first mode is a mode in which at least one of the number of nodes (12) and the number of edges (14) is reduced than the number included in the determined graph.

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: The present invention provides an information processing system for more appropriately classifying elements that constitute an information processing device or the like. This information processing system is provided with: a means that, on the basis of information indicating the relationship between a plurality of elements that constitute a system, acquires, for first elements to be classified, a set of second elements capable of arriving at the first elements via a relationship of arbitrary numbers; and a means that, on the basis of the set corresponding to the first elements, classifies each of the first elements in any of a plurality of roles.

Abstract: Disclosed are an event estimation device, etc., which are capable of estimating with high precision whether a communication is singular. Provided is an event estimation device (101), comprising: a model creation unit (102) which creates a model which, on the basis of a frequency with which a communication is executed, computes that a degree of singularity which represents the extent to which the communication is singular is high if the frequency is low, and computes that the degree of singularity is low if the frequency is high; and an estimation unit (103) which computes the degree of singularity by applying the model to the frequency relating to a given communication, and if the computed degree of singularity satisfies a standard, estimates that the given communication is singular, and if the computed degree of singularity does not satisfy the standard, estimates that the given communication is not singular.

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 means and a transmission-interval determination means. The risk calculation means receives, from a plurality of moving bodies, state information that includes locations and velocities and is transmitted at provided time intervals. The risk calculation means also computes the distance between and relative velocities of two moving bodies. The transmission-interval determination means 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 said moving bodies.
