PROBLEM TO BE SOLVED: To provide a log management system capable of suppressing and monitoring illegality on a holiday or in the night, when a system manager is absent and monitoring is not complete, by making it difficult to conceal the illegality by revising the contents of a log file. SOLUTION: This log management system is provided with a main managing means for recording the manipulation and/or operation of a computer system and preserving it as a main log file and a subordinate managing means for recording the manipulation and/or operation of the computer system and preserving it as a subordinate log file and for collating the main log file with a subordinate log file and discriminating whether recorded data are coincident or not. |
