Management method of computer system, computer management system, and computer management program

A management system of a computer system for preventing an unauthorized use of an application program, the use of which is prohibited under predetermined use conditions, the computer system comprising:

• hardware including a processor;
• an operating system (O/S) for executing a program;
• a dynamic link library (DLL) storing a plurality of dynamic link library (DLL) files to be used as a part program;
• and
• a plurality of application programs that use at least one of the DLL files as a part program, wherein
• the management system of a computer comprises:
• a storing means for storing, in correlation with the predetermined use conditions, a DLL file or a set of two or more DLL files for identifying the application program from among the DLL files to be used by the prohibited application program;
• a detecting means for detecting use conditions when the activation of the application program is requested;
• a detecting means for detecting a DLL file or a set of the DLL files to be used by the application program, the activation of which is requested;
• a judging means for judging whether the detected use conditions are the stored predetermined use conditions and whether the detected DLL file or the detected set of the DLL files includes the predetermined DLL file or the predetermined set of the DLL files stored in correlation with the predetermined use conditions;
• and
• a means for terminating the application program, the activation of which is requested, when the detected use conditions are judged to be the stored predetermined use conditions and the detected DLL file or the detected set of the DLL files is judged to include the predetermined DLL file or the predetermined set of the DLL files.

A computer management program for preventing a program from being activated and making a computer operate as:

• a storing means for managing a DLL file or a set of two or more DLL files to be called by a program, the activation of which should be prevented, in correlation with use conditions;
• a judging means for judging, when the activation of an application program is requested, whether DLL files to be used by the application program include the predetermined DLL file or the predetermined set of the DLL files stored in the storing means;
• and
• a terminating means for terminating the application program, the activation of which is requested, when the DLL predetermined file or the predetermined set of the DLL files is judged to be included.
