A friend of mine asked me the other day about just how much info a network admin can gather from monitoring VPN access. Despite working on VPNs almost exclusively for many years now, I don’t know the answer so I pass it on to all you smart people.
I know when you connect to a VPN, all network traffic goes through it, so in theory, the answer is “everything.” In practice, I don’t see network admins digging through terrabytes of network traffice searching for that time you referred to a coworker as an asshole. And I’ve certainly never been confronted with doing stuff I shouldn’t do while connected, even though I’m certain that more than once I’ve said stuff on IM or ended up on a NSFW webpage or whatever.
So what’s the real answer? If I piss off a VPN higher-up, can they start watching my IMs? Find that message board where I called the CEO a dick? Figure out that I’m spending half my day playing that farm game on Facebook?
I suspect the answer to all of these is “yes, but it would take forever to dig through all the network traffic, so they probably won’t” but hell if I know the real answer. So what is it, smarties?
(and, for the record, I’m not looking to do anything bad on the VPN that I haven’t already done a gazillion times over the past 4-5 years. I’m just curious since the friend asked me and I truly didn’t know)
