Database Audit

When the log entries are expanded, they also include the account number of the user and the online computer or device ID that applied each operation recorded in the log.

If any tampering with the database is suspected, a database audit is performed, which consists of reviewing the log to examine all accesses and operations applied to the database during a certain time period.

When an illegal or unauthorized operation is found, the DBA can determine the account number used to perform the operation.
