Classification: CPC H | IPC H

Claim 3:
4. A method for analyzing abnormal traffic comprising: a receiving step of receiving traffic from a device via any of a plurality of communication paths in which different communication methods are used; a multiple communication management step of identifying a communication path through which the traffic is transmitted; an analysis method determination step of determining an analysis algorithm of a plurality of analysis algorithms and one or more analysis parameters for detecting abnormality of the traffic according to the communication path identified in the multiple communication management step, wherein:
the one or more analysis parameters includes a degree of detail of attack detection,
the degree of detail of attack detection is indicative of a level of threat associated with the traffic, and
each of the plurality of analysis algorithms is configured to perform an analysis for attack detection with respect to a specific communication path based on a determined degree of detail of attack detection; and an analysis step of analyzing whether or not the traffic is abnormal traffic by using the analysis algorithm and the determined one or more parameters in the analysis method determination step; and an analysis result recording step of recording a result of analysis performed in the analysis step.
