A method for monitoring stored procedures is disclosed. The method performs on-line and inline monitoring of stored procedures for detecting table access operations performed by the procedures. This allows the enforcing of access control policies, correlation rules and audit rules on stored procedures. The monitoring is performed using mapping information gathered about each stored procedure that can be executed by a database server. The method comprises parsing an incoming transaction submitted by a client; determining whether the incoming transaction includes an invocation of a stored procedure; obtaining a query group corresponding to the stored procedure; applying an access control policy on the query group; and asserting an unauthorized event if the query group is not compliant with the access control policy.
