It may not strictly be illegal but at our company we have taken the tack that we just don’t decrypt users traffic, especially sensitive usernames and passwords to sites like online banking and healthcare, it’s not worth the risk of an employee getting compromised and then coming back and saying that we had the data so we must have been the one’s that got compromised.   I guess it’s more of a management decision, but I imagine depending on what country/state you are in there are also some legal issues to content with.

Mark, I'm curious about your statement that it's not legal to decrypt users' traffic without them being aware. Since companies are constantly asserting that they own all the data on their devices and network, why would a user's personal traffic, even if it's of a sensitive nature, be any different?

Thanks!

Because technically it’s not legal to decrypt users traffic without them being aware.  It could reveal things like online banking passwords and such.  We use PA firewalls and they have the ability to do SSL decryption but I can’t actually see the traffic, the firewall uses layer 7 inspection to and it’s own internal rule base/security signatures do decide if the traffic gets passed or not.

Curious, why wouldn't you recommend doing our own MITM attack? (And how would we do it?)

All you can really do at that point is analyze the endpoints and see if you can get any info from that.  Well I guess you could setup your own man-in-the-middle attack, but I wouldn’t suggest it.

Subject: [Wireshark-users] dissecting HTTPS traffic

Hey folks,

One of our clients has recently been having their WAN bandwidth eaten up, and we've narrowed it down to one executive's computer.

Now we want to dissect that computer's traffic to see what it's doing. However, much of it is HTTPS, so we can't see the content. Any suggestions on getting a useful analysis?

Thanks!
