<p><P>PROBLEM TO BE SOLVED: To prevent an operation error or unauthorized operation of an operator of an IT system during modification, and reduce the burden of additional check for advance preparation, or a response to false detection and omission. <P>SOLUTION: The system includes: an operation log collection means 4 which collects an operation log in a development/test environment or in a production environment; a log pattern editing means 3 which forms an operation log pattern by the operation log in the development/test environment and corrects it based on a difference between the production environment and the test/development environment to form a base pattern of the operation log pattern; an operation log check means 5 which compares the operation log in the production environment with the base pattern of the operation log pattern to check a wrong operation; an alert output means 7 which outputs an alert when a wrong operation is detected; and an operation log pattern information storage means 11 which stores, when operation continuation is approved by an alert receiver, the base pattern of the operation log pattern modified by the operation log in the production environment, or stores it as a derivative pattern. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
