Consider this typical scenario. One of your company employees has a meeting across town. They arrive a bit early and go into a local coffee shop to connect to their wireless network because there is an email they just have to send. They may have heard somewhere that “open” wireless networks are bad and we should not connect to them, but this email is really important. The employee composes the email and sends it and says, “nothing blew up, so it must not be as bad as I’ve heard.”
So, is that right? Is it safe? How can you know?
