If I run a service via docker or anything else on there, the outside world doesn&amp;#x27;t see it unless I open a way in elsewhere. For extra paranoia, the network leg that others can connect to (wireless AP &amp;amp; wired network ports in the guest room) is also separate and only sees parts of the server(s) I explicitly want it to (you can do this with vlans and such depending on your kit, I&amp;#x27;ve actually just got an extra NIC on the router).&lt;p&gt;Never assume a process&amp;#x2F;service&amp;#x2F;container&amp;#x2F;etc is at all locked down, unless you have checked it out yourself or have it sufficiently wrapped in things you have locked off.</text><parent_chain><item><author>rmetzler</author><text>&amp;gt; DevOps, Developers, and IT practitioners often misconfigure some of the following:
