But you have the possibilty to migrate a Password File to a newer format. During this migration the password complexity rules are ignored. You have to use different names for the involved Password Files.

A strong password for remote authentication using SYSDBA, SYSBACKUP etc. privilege is a good starting point to archieve a higher level of security accessing the database from the outside. The decision of Oracle to enforce a strong(er) password during creation time of the Password File is a little but good enhancement of the orapwd utility.

It is our duty as database administrators to nudge users towards more complex passwords, and Oracle furnishes us with the tools to do so. If you created your database using the DBCA (configuration assistant), you should have the native password complexity functionality switched on by default; if you created your database using the CREATE DATABASE statement, you will need to enable it yourself.

It is easily done. In your $ORACLE_HOME/rdbms/admin folder you should find the utlpwdmg.sql file. What this script contains depends largely on what version of the Oracle database you have installed: before 11g, it would install the verify_function function; for 11g, it would install verify_function_11G; and for 12C, it would additionally install ora12c_verify_function and ora12c_strong_verify_function.

These functions all accept a username and a password; they proceed to test the complexity of the password in ways that we will go into later. They are attached to user profiles (utlpwdmg.sql attaches them to the DEFAULT profile, however you can edit this if you have a more granular system). Once attached to the profile, every time a user of that profile creates a new password Oracle will automatically refer to the function to examine its strength.

However, while Jennifer Lawrence and Rihanna were probably guilty of not changing their passwords regularly enough, it was the weakness of their chosen passwords that probably left them most exposed. The Oracle rules enforcing complexity can be found within the verify functions themselves.
