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.
