Based on a normal model, it is detected whether or not an event signal of a computer system is anomalous. In parallel with the normal-model-based anomaly detection, it is detected based on a rule whether or not the event signal is anomalous. Then, a final anomaly detection result is generated by performing comprehensive determination based on detection results of the normal-model-based anomaly detection and the rule-based anomaly detection.

Anomaly detection device

There is provided a system model evaluation system including a system model candidate creation part configured to create a candidate(s) of a system model by changing a pattern of selecting an inter-sensor-value relationship created by using sensor values acquired from sensors arranged in a system to which the system model is directed. This system model evaluation system further includes a system model evaluation part configured to evaluate the candidate(s) of the system model by inputting predetermined evaluation data to the created candidate(s) of the system model.

System model evaluation system, operation management system, system model evaluation method, and program

A content distribution system is provided, in which time-shift viewing among a plurality of devices can be realized. The system includes, a device group management unit which manages a group to which audio-visual devices capable of realizing time-shift viewing mutually belong; a viewing state management unit which acquires viewing information of a content by the audio-visual device, and a time shift control unit which transmits permission information for viewing the content in a time-shifted manner and the viewing information of the content acquired by the viewing state management unit, to the audio-visual device included in the group managed by the device group management unit, in response to a time shift request issued by the audio-visual device.

Content distribution system, content distribution server, content distribution method, and content distribution program

An electronic mail transmitting and receiving system that is capable of predicting whether or not the user can access the electronic mail transmitting and receiving system, and which is also capable of automatically controlling whether or not the electronic mail addressed to the user is transferred to an auxiliary device such as facsimile equipment, predetermined by the user. The electronic mail transmitting and receiving system is provided with a mail system monitor which monitors arrival, transmission, and reception of the electronic mail addressed to the user, a transfer propriety data generator that anticipates whether or not the user can access the mail system according to the result of the monitor and which generates a transfer propriety data based on the result of the anticipation. A mail transfer device refers to the transfer propriety data periodically at a fixed time interval. As far as it is confirmed that the transfer is appropriate, the mail transfer device transfers the electronic mail addressed to the user in the mail system to an auxiliary device predetermined by the user.

Method and apparatus for transmitting and receiving electronic mail based upon user availability

A data sharing system in which a server comprises a connection party holding unit for holding access information, and a terminal equipment comprises a database for acquiring the corresponding data so to submit it to the application program when an application program issues a reference request of data and a connection party deciding unit for deciding a connection party calculating machine with reference to access information depending on the necessity, the database judging whether there exists a data name of the data specified by the reference request in the connection party holding unit when a reference request is issued, instructing the connection party deciding unit to decide a calculating machine of a connection party when there exits, and further issuing a data transfer request to the decided connection party, so to acquire the corresponding data.
