Using role separation
Role separation is a database server option that allows users to perform different administrative tasks. Role separation is based on the principle of separation of duties, which reduces security risks with a checks-and-balances mechanism in the system. For example, the person who determines what to audit (DBSSO) must be different from the person who monitors the audit trail (AAO), and both must be different from the person who is responsible for the operations of the database server (the DBSA).
