2.1.35 Ensure the TFTP daemon is configured to operate in secure mode

Information

If the Trivial File Transfer Protocol (TFTP) server is required, the TFTP daemon must be configured to operate in secure mode.

Restricting TFTP to a specific directory prevents remote users from copying, transferring, or overwriting system files.

Solution

Configure the TFTP daemon to operate in secure mode by adding the following line to "/etc/xinetd.d/tftp" (or modify the line to have the required value):

server_args = -s /var/lib/tftpboot
