UNAUTHORIZED ACCESS MONITOR PROGRAM, UNAUTHORIZED MONITOR METHOD, AND UNAUTHORIZED MONITOR SYSTEM

Title:

UNAUTHORIZED ACCESS MONITOR PROGRAM, UNAUTHORIZED MONITOR METHOD, AND UNAUTHORIZED MONITOR SYSTEM

Document Type and Number:

WIPO Patent Application WO/2007/077624

Kind Code:

A1

Abstract:

It is possible to provide an unauthorized operation monitor program for monitoring an unauthorized computer operation by calculating an unauthorized score by reflecting a suspicious value indicated by a series of operations by a user operating a computer. When an unauthorized score indicating probability of an unauthorized operation is calculated for an object event, a suspicious value (PSV) corresponding to the level of the unauthorized score calculated is set. When a new even occurs next time, for the score (original score) calculated for the new event, an unauthorized score reflecting a time difference between the PSV set at the previous event and the previous event is calculated. When operation of high probability of unauthorized access is continuously performed or when operation of a high suspicious value is repeated, a high score is calculated as an unauthorized score.
