2.2.21 Ensure the TFTP server has not been installed - TFTP server package installed if not required for operational support.

Information

The operating system must not have the Trivial File Transfer Protocol (TFTP) server package installed if not required for operational support.

Rationale:

If TFTP is required for operational support (such as the transmission of router configurations) its use must be documented with the Information System Security Officer (ISSO), restricted to only authorized personnel, and have access control rules established.

Solution

Remove the TFTP package from the system with the following command:

# yum remove tftp-server
