=====Description=====
''echo'' is a network service that responds to clients with the data sent to it by the client. This service is intended for debugging and testing purposes. It is recommended that this service be disabled.

=====Rationale=====
Disabling this service will reduce the remote attack surface of the system.

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

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