Configure the TFTP daemon to operate in secure mode with the following command:

$ systemctl edit tftp.service

Insert the following between the two sets of comments, making sure to add the "-s" option with a nonroot ("/") directory.

[Service]
ExecStart=
ExecStart=/usr/sbin/in.tftpd -s /tftp

Check Contents

Note: If a TFTP server is not installed, this requirement is Not Applicable.

Verify the TFTP daemon is configured to operate in secure mode.

Check if a TFTP server is installed with the following command:

$ dnf list --installed tftp-server

Installed Packages
tftp-server.x86_64 5.2-37.el9 @appstream

If a TFTP server is installed, check for the server arguments with the following command:

$ systemctl cat tftp | grep ExecStart=

ExecStart=/usr/sbin/in.tftpd -s /var/lib/tftpboot

If the "ExecStart" line does not have a "-s" option, and a subdirectory is not assigned, this is a finding.
