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.

Check to see if a TFTP server has been installed with the following command:

# yum list installed tftp-server
tftp-server-0.49-9.el7.x86_64.rpm

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:

# yum remove tftp-server
