PROBLEM TO BE SOLVED: To provide a system and method for maintaining database security in a fixed level, for an operation from a management tool or middleware provided by a database vender. SOLUTION: A database trigger 50 mounted on an update target database 30 compares a reference level 17 owned by a user with a disclosure level 22 of the target database, and when the reference level 17 is lower than the disclosure level 22, the database trigger 50 sends the warning mail of an unauthorized access to a system manager, and when the reference level 17 is a disclosure level 22 or more, authorizes access, and collects update history information for the update target database 30 in an update history database 40.
