Abstract: An acquisition unit acquires a communication feature for normal communication of communication equipment. If a data count or a data acquisition period for the acquired communication feature exceeds a predetermined value, an amplification unit amplifies the data count for the communication feature by a plurality of predetermined schemes in accordance with data counts for respective groups, each group sharing a same 5-tuple. A creation unit creates, for each of the predetermined schemes, reference value information for normal communication of the communication equipment through learning using the amplified communication feature. A determination unit determines accuracy of abnormality detection for each of the predetermined schemes using an anomaly score representing a deviation of test data representing a communication feature for abnormal communication from the reference value information.

Abstract: An analysis server accumulates an alert of communication determined not to be normal communication on the basis of a model indicating a feature of normal communication in a storage unit. Then, the analysis server performs clustering of alerts obtained by excluding an alert having a different category variable from communication data used for learning of the model from the accumulated alerts by using a feature amount of communication included in the alert. Thereafter, the analysis server determines, for each cluster generated by clustering, whether or not the cluster includes the same type of alert. Then, the analysis server outputs a result of clustering and a determination result as to whether or not each cluster includes the same type of alert.

Abstract: An analysis server acquires observation information including a transmission source IP address, a transmission source MAC address, a transmission destination IP address, and a transmission destination MAC address in communication from each of sensing devices. The analysis server estimates a topology of a network on the basis of the acquired observation information. On the basis of the estimated topology, an analysis server creates a monitoring list indicating communication that is a target for transmission of the observation information for each sensing device such that any one sensing device on a path of the communication transmits the observation information of the communication for each piece of communication in the network, and transmits the monitoring list to the sensing device. Thereafter, each sensing device transmits the observation information of the communication to the analysis server on the basis of the monitoring list.

Abstract: A determination unit determines necessity of relearning of an initial learning model based on at least one of information regarding the initial learning model generated by learning initial learning data known to be normal, information regarding over-detection data over-detected by an abnormality detection system that uses the initial learning model, and information regarding an over-detection model generated based on the over-detection data. A notification unit notifies of determination result by determination unit.

Abstract: A packaged article includes a packing bag which includes a welded portion that hermetically seals a container compartment in which a fluid content is contained. The welded portion includes a weak sealant section configured to be parted when the container compartment is pressed to communicate the container compartment and the exterior of the packing bag. A strong sealant section is configured to maintain a welded state at the time when the weak sealant section is parted. The container compartment includes a primary container section and a secondary container section. The secondary container section includes a narrow neck that is narrower than the primary container section in a width-wise direction, which corresponds to a direction in which the weak sealant section extends. The secondary container section is in communication with the primary container section at the narrow neck. The secondary container section is located adjacent to the weak sealant section.
