<P>PROBLEM TO BE SOLVED: To enable a high-accuracy traffic flow to be grasped with a reduced amount of effort on the basis of functions normally usable at a general-purpose firewall device. <P>SOLUTION: A traffic passage route analysis method includes: step S2 of obtaining, from predetermined plural firewall devices, information constituting an arrival date/time of each traffic, the firewall device reached, and a transmission origin and a destination address, with the aforementioned items correlated with one another, to define the information as individual traffic information; step S3 of grouping the individual traffic information based on matching between the transmission origin and the address, and proximity within a predetermined criterion of arrival date/time, to define the grouped traffic information as summarized traffic information; and step S4 of acquiring, for an individual summarized traffic, a permutation of the firewall devices which individual traffics have reached, in the sequence of the arrival dates/time of the individual traffics belonging to the individual summarized traffic, to estimate the permutation as a passage route for the entire traffic flow from the transmission origin to the address, the flow being common to the individual summarized traffic. <P>COPYRIGHT: (C)2013,JPO&INPIT |
