Perhaps you should read the submission. The larger point here is that even if you set up a network in the first place which is genuinely airgapped, as time passes and systems evolve there will be constant pressure from within and without to re-establish a network connection <i>somewhere</i> in order to make everyone&#x27;s lives easier and eventually, whether deliberate or inadvertent, a connection will be made (and of course, we know that the NSA has a variety of infiltration and exfiltration methods to get across air gaps, such as dropping flash drives and waiting for an insider to be foolish enough to bring it inside).<p>Believing that an air gap exists or will continue to exist indefinitely is hence setting yourself up for some unpleasant surprises in the future, and encourages weak security designs where the network&#x2F;system is crunchy on the outside and all delicious and soft and gooey on the inside. (Which is more secure, to have your local WiFi set up with WPA or whatever and have employees telnet into servers, or just go Google-style and have fully encrypted end to end links without requiring any belief in security of the links?)
