Uninstall tftp-server Package

An XCCDF Rule

Description

The tftp-server package can be removed with the following command: 

 $ sudo yum erase tftp-server

Rationale

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 Securty Manager (ISSM), restricted to only authorized personnel, and have access control rules established.
