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 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® WebLogic Portal 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 RXI.
  • The password for the database listener. Oracle recommends that you do not configure a password for the database listener as that will enable remote administration. For more information, refer to Oracle® Database Net Services Reference 12c Release 1 (12.1).
