Configure Strong Passwords on the Database

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

Ensure all your passwords are strong passwords.

You can strengthen passwords by creating and using password policies for your organization.

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 RXC, OPA, and RXC_PD. You can run the Set Password (set_pwd) utility to set stronger passwords for the default Oracle Clinical schemas. For details on using the utility, refer to the Oracle Clinical Administrator's Guide.
• 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.

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.
