An information asset management system in a network environment includes a monitoring program 11 that monitors operation events performed by users and creates terminal logs 12, a terminal log collection program 21 that stores an integrated log 22 created by collecting the terminal logs 12, and a correlation analysis program 31 that analyzes the whereabouts of information assets using the integrated log 22. When the user exports an information asset from the network environment and when the user imports the information asset into the network environment, the monitoring program 11 monitors these export and import events including feature values of the information assets. The correlation analysis program 31 compares a pre-export feature value of each information asset with a post-import feature value of each information asset to determine whether the information assets are identical and reports a list of information assets in the organization.
