1Z0-052 - Implementing Oracle Database Security
MainDatabase Security and Principle of Least PrivilegeWork with Standard Database Auditing- What is Standard Auditing? In standard auditing, you audit SQL statements, privileges, schema objects, and network activity. You configure standard auditing by using the AUDIT SQL statement and NOAUDIT to remove this configuration. You can write the audit records to either the database audit trail or to operating system audit files.
- Who Can Perform Standard Auditing? Any user can configure auditing for the objects in his or her own schema, by using the AUDIT statement. To undo the audit configuration for this object, the user can use the NOAUDIT statement. No additional privileges are needed to perform this task. Users can run AUDIT statements to set auditing options regardless of the AUDIT_TRAIL parameter setting. If auditing has been disabled, the next time it is enabled, Oracle Database will record the auditing activities set by the AUDIT statements.
- When Are Standard Audit Records Created? When auditing is enabled in the database and an action configured to be audited occurs, Oracle Database generates an audit record during or after the execution phase of the SQL statement. Oracle Database individually audits SQL statements inside PL/SQL program units, as necessary, when the program unit is run.
The generation and insertion of an audit trail record is independent of a user transaction being committed. That is, even if a user transaction is rolled back, the audit trail record remains committed.
Statement and privilege audit options in effect at the time a database user connects to the database remain in effect for the duration of the session. When the session is already active, setting or changing statement or privilege audit options does not take effect in that session. The modified statement or privilege audit options take effect only when the current session ends and a new session is created.
In contrast, changes to schema object audit options become immediately effective for current sessions.
