The tftp daemon must be disabled on AIX.
An XCCDF Rule
Description
<VulnDiscussion>The tftp service allows remote systems to download or upload files to the tftp server without any authentication. It is therefore a service that should not run, unless needed. One of the main reasons for requiring this service to be activated is if the host is a NIM master. However, the service can be enabled and then disabled once a NIM operation has completed, rather than left running permanently.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
