Disable other services

This section explains why you should disable other unused services.

In addition to not using Telnet, the Health Record Locator standard configuration does 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 a method for managing and reporting information about different systems.

Restricting these services or information does not affect the use of Health Record Locator standard configuration. If you are not using these services for other applications, disable these services to minimize your security exposure. If you need SMTP, identd, or SNMP for other applications, ensure to upgrade to the latest version of the protocol to provide the most up-to-date security for your system.
