====== 2.1.9 Ensure tftp server is not enabled (Scored)======
=====Profile Applicability=====  
<code>
Level 1 - Server 
Level 1 - Workstation
</code>

=====Description=====
Trivial File Transfer Protocol (TFTP) is a simple file transfer protocol, typically used to automatically transfer configuration or boot machines from a boot server. The packages ''tftp'' and ''atftp'' are both used to define and support a TFTP server.

=====Rationale=====
TFTP does not support authentication nor does it ensure the confidentiality or integrity of data. It is recommended that TFTP be removed, unless there is a specific need for TFTP. In that case, extreme caution must be used when configuring the services.

=====Audit===== 
Verify the ''tftp'' service is not enabled. Run the following commands and verify results are as indicated:
<Code:bash>
grep -R "^tftp" /etc/inetd.*
</Code>
No results should be returned \\ \\
check ''/etc/xinetd.conf'' and ''/etc/xinetd.d/*'' and verify all ''tftp'' services have ''disable = yes'' set.

=====Remediation===== 
Comment out or remove any lines starting with ''tftp'' from ''/etc/inetd.conf'' and ''/etc/inetd.d/*''.\\
Set ''disable = yes'' on all ''tftp'' services in ''/etc/xinetd.conf'' and ''/etc/xinetd.d/*''.
