Disable Unused Services

The Oracle Clinical and RDC Onsite applications do not use the following services or information for any functionality:

• Simple Mail Transfer Protocol (SMTP). This protocol is an Internet standard for e-mail transmission across Internet Protocol (IP) networks.
• Identification Protocol (identd). This protocol is generally used to identify the owner of a TCP connection on UNIX.
• Simple Network Management Protocol (SNMP). This protocol is one method for managing and reporting information about different systems.

Therefore, restricting these services or information will not affect those Oracle applications. If you are not using these services for other applications, Oracle recommends that you disable these services to minimize your security exposure.

If you need SMTP, identd, or SNMP for other applications, be sure to upgrade to the latest version of the protocol to provide the most up-to-date security for your system.

In addition, Oracle recommends that you remove unused Oracle Clinical User accounts if you are upgrading from earlier releases.
