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: An execution control system (2000) determines whether to permit execution of a target application (30). The determination includes first determination and second determination. The second determination is performed when the first determination cannot determine whether to permit the execution of the target application (30). The execution control system (2000) executes the target application (30) in a protected environment after the first determination is finished and while the second determination is performed.

Abstract: An information processing apparatus (2000) extracts, from a communication history (20) representing a history of network communication performed by each of a plurality of mobile terminals (10), a communication history (20) indicating communication related to a similar attack. Herein, the communication history (20) includes positional information about the mobile terminal (10). The information processing apparatus (2000) generates attack information related to an attack on the mobile terminal (10) by using positional information indicated by each of the extracted communication histories (20), and outputs the generated attack information.
