Not sure, I'll try to describe it a bit better. I do security audits
for clients and some of them have have VLANs setup, what I want to
look are things like what would I need to compromise to see the most
traffic, or how to try to get from a guest VLAN to the one that
handles card processing when doing PCI audits.
For hopping, there are tools out there but I've not looked at them
just because I haven't had the facilities to test them.
I'm finding it hard to describe just because I don't know enough about
the area to fully articulate what I'm trying to do and I don't really
know what I want/need to do till I've got at least the bones of a lab
set up so I can start playing with things.
Its late on a Friday, I hope that makes sense.
