User Administration and Authentication 

Before you can work with the database system, you must log on to the database instance with a database tool or via an interface. You log on with your user name. You enter your password and the database system authenticates your identity using this password.

Hazards

·        Unauthorized Access of the Database Instance

A person who is not authorized to access the database instance learns the user name and password of an authorized user. Particularly at risk are standard users with standard passwords that are commonly known.

The person logs onto the database instance using the identity of the authorized user.

Activities

·        Changing the Passwords of Standard Users

·        Checking Log Files for Failed Logon Attempts
