<div dir="ltr"><div class="gmail_extra">A lot of businesses offer free wi-fi access within their walls as a perk of being there.</div><div class="gmail_extra"><br></div><div class="gmail_extra">I have a friend that is a business owner that does NOT offer it because of "security" reasons. In fact, in order to get on his wifi, he can't just give you the password, he actually has to whitelist your MAC address into his router or something like that.</div>
<div class="gmail_extra"><br></div><div class="gmail_extra">His web developer set it up this way because their custom point of sale program is just a website. And they don't use https. So my question is, if that website login form was accessed over non-secure http is the login just send in plain text in packets? Could someone theoretically observe that with wire-shark without even being logged in to the wi-fi network? Or do you need to be connected to the wi-fi router in order to be able to do that?</div>
<div class="gmail_extra"><br></div><div class="gmail_extra">I think it's the former but I'm not a wire-shark expert, can someone confirm? (Either way I will tell him he needs https). And I want to encourage him to provide free wi-fi, and if his POS is secured over https it shouldn't make his business anymore vulnerable than he is now, is that correct?</div>
