Re: Wireless Audit Reports

["Maudite MLRL" <maudite.mlrl () gmail com>]

I have had to do the same thing on quite a few occasions.

We do spend a good amount of time on this issue during our tests, but
we add GPS data to our findings. We would also use kismet validate
that the address ranges of the APs broadcast side did not belong to
the clients network.

Microsoft Streets and maps comes with a GPS that is actually a
repackaged Pharos 360 USB GPS for about a $100. This works with net
stumbler, kismet, etc.

Driving around the target location gives a decent triangulation of
actual positions of the access points so you can ID what's in and out
of the building. This actually cuts down on what you should be
validating on foot. We are also able to drop the data to a street map
and/or satellite overlay image for evidence of assumptions in the
audit findings.

Because our clients would actually be housed in buildings with
multiple businesses, we would work to validate that the points are
located in other businesses. Record the SSID owning company, location
and possibly a contact. This took the most time, but since our audits
were reoccurring, it was useful for future visits.

Other ways we would validate is sweep the wired network for MACs
belonging to AP vendors. We understood that this could be faked, but
we also looked at the skill level of the employees on site and
associated a risk/possibility level that this could occur.


Hope this helps.
