Configure strong database passwords

This section discusses configuring strong passwords on the database.

Repeat the following basic rule of security management:

Ensure all passwords are strong. You can strengthen passwords by creating and using password policies for your organization. For guidelines on securing passwords and for additional ways to protect passwords, refer to the Oracle® Database Security Guide specific to the database release you are using.

You should modify the following passwords to use your policy-compliant strings:

• Passwords for the database default accounts, such as SYS and SYSTEM.
• Passwords for the database application-specific schema accounts, such as Gateway.
• Password for the database listener. Oracle recommends that you do not configure a password for the database listener as this enables remote administration. For more information, refer to the section Removing the Listener Password of Oracle® Database Net Services Reference 11g Release 2 (11.2).
