Weak passwords not allowable

Weak passwords, i.e. those are easy to guess and amenable to cracking by hackers, come in many forms. Some are as easy as just common terms: abc123, password, the user’s user id, etc. In order to prevent a weak password, Oracle’s Password Management Function is handy. It checks the password the user chooses and uses a stored procedure to check to see if it conforms to a standard established by the DBA. This is quite easy to implement and the details can be found in Section Password Management Function in Chapter 4.
