Configure Strong Password on the Database and WLS

Although the importance of passwords is well-known, the following basic rule of security management is worth repeating:

Make sure all your passwords are strong passwords.

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 Weblogic Server default accounts, such as weblogic.
• Password for the database listener. If you do not configure the database listener to require an authorization password, you unnecessarily expose the underlying database service names to unauthorized individuals.
