Re: dissecting HTTPS traffic

[Mark Semkiw <Mark.Semkiw () commtrans org>]

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!
