I&#x27;ve worked with such a mimic.
He did a security audit, then scrapped the whole system because there was a completely unfiltered network interface, and no matter what other security was in place that would never ever be good enough on a GNU&#x2F;Linux system.
&quot;All interfaces must have strict filtration, only allowing traffic on previously approved ports as per system and application specifications.&quot;<p>The interface in question was called &quot;lo&quot;.<p>I don&#x27;t work there any more.
