Discussion

Removing the "tftp-server" package decreases the risk of the accidental (or intentional) activation of tftp services. If TFTP is required for operational support (such as transmission of router configurations), its use must be documented with the information systems security manager (ISSM), restricted to only authorized personnel, and have access control rules established.

Check Content

Verify OL 9 does not have a tftp server package installed with the following command:

$ dnf list --installed | grep tftp-server

If the "tftp-server" package is installed, this is a finding.
