Discussion

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.

Check Content

Verify a TFTP server has not been installed on the system with the following command: 
 
$ sudo yum list installed tftp-server 
 
tftp-server.x86_64 5.2-24.el8 
 
If TFTP is installed and the requirement for TFTP is not documented with the ISSO, this is a finding.

Fix Text

Remove the TFTP package from the system with the following command: 
 
$ sudo yum remove tftp-server
