<P>PROBLEM TO BE SOLVED: To provide an information processing method and the like capable of appropriately detecting an abnormality in accordance with increase/decrease information on a risk. <P>SOLUTION: A control section of a server computer 1 determines whether or not a value based on input information exceeds a first threshold range stored in a storage section. When determining that the value exceeds the first threshold range, the control section also determines whether or not frequency or duration that the value exceeds the first threshold range also exceeds a second threshold range stored in the storage section. The control section also acquires increase/decrease information on a risk from a security server 4 and corrects the first threshold range and the second threshold range based on the acquired increase/decrease information on the risk. When determining the frequency or the duration exceeds the corrected second threshold, the control section outputs abnormality information indicating presence of an abnormality to a management computer 3. <P>COPYRIGHT: (C)2012,JPO&INPIT |
