General security principles

This section describes fundamental security principles for using any application securely.

General security principals include:

• Keep software up-to-date: Keep all software versions and patches up-to-date.
• Keep up-to-date on the latest security information and critical patches: Oracle continually improves its software and documentation. Critical patch updates are the primary means of releasing security fixes for Oracle products to customers with valid support contracts. Oracle recommends you to apply these patches as soon as they are released.
• Managing default user accounts: Lock and expire default user accounts.
• Closing all open ports when not in use: Keep only the minimum number of ports open. You should close all ports when not in use.
