Abstract: An analysis condition for security risk for a data flow in a system to be analyzed is automatically generated. An analysis condition generating apparatus lA generates from a natural sentence, using ontology in which a relationship is described between one or more nodes on a data flow graph that indicates a data flow in a system to be analyzed and one or more edges that indicate an event related to the nodes, graph structural data indicating the relationship between the nodes and the edges, and generates an analysis condition for analyzing security risk for the system to be analyzed based on the graph structural data.

Abstract: A policy evaluation apparatus (2000) acquires, with respect to each of a plurality of control groups (10) including an evaluation target group, control policies (20). Each of the control policy (20) indicates execution permission/non-permission of an application. Further, the policy evaluation apparatus (2000) compares an evaluation target policy being the control policy (20) of the evaluation target group with other plurality of control policies (20), and generates evaluation information (30) based on the comparison result.

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: Provided is an information processing device which is capable of suppressing a deterioration in accuracy of detecting an anomaly and accuracy of analyzing the anomaly, while suppressing an increase in an amount of data to be stored. The information processing system includes anomaly detection unit that collects event data indicating a predetermined event detected in a process of a device to be monitored, determines whether a predetermined index value related to the event exceeds a preset first threshold, and instructs enhanced monitoring of the device to be monitored and the process related to the event when the index value exceeds the first threshold, and collection instruction unit that determines an additional event being an event to be additionally monitored when the enhanced monitoring is instructed, and instructs the device to be monitored, which is subjected to the enhanced monitoring, to monitor the determined additional event.
