Subject: Wireless Audit Reports
Hi,
I work in an environment that has a policy that does not permit
wireless devices. We still do an "audit" of the area to ensure that
there are no wireless devices in our area. I wish to prove that there
are no devices. Being in a city, there are literally hundreds of
wireless networks present - perhaps up to 50 in any one given area of
our building. I have tracked the signals down and have determined
that
there are no rogue access points or peer networks hidden in our
portion
of the building.
Now a traditional wireless audit would be easy. I could report
the signal strengths of our devices, if the SSID's are correct, are
non-broadcast, etc. That would be an easy report to create after data
collection. In this case, I am trying to prove a negative. I can
list
networks, signal strengths, etc. but I feel like I am fluffing the
report with meaningless and time wasting statistics. Does anyone have
any experience in what they would report under these circumstances?
Being on the Las Vegas Strip crowded with a bunch of other casinos,
shops, malls, Starbucks, and everything else, the wireless spectrum over
here is pretty crowded and we get a fair amount of bleed into our
property. Having had to do something like this before, I went with the
"traditional" type of report like you detailed, listing all detected
networks, SSIDs, channels, encryption enabled, etc... but from a
different slant. The purpose was twofold- one was to show how much
signal was invading our airspace and how strong it was. Since everyone
around here is WiFi crazy, the airspace is heavily polluted in some
areas with a lot of signal overlap especially with some of these people
slapping amps and huge antennas on their APs to compensate for loss of
signal (you would be surprised how far away you can pick up some
properties' signals even without Yagis or anything special). Second
(more important) was to show the number, if any, of networks that bled
into here that were open or insecure. We don't want any of our devices
accidentally associating themselves with those networks, and want to
make sure that those networks can't be used to hurt us.
