Points of Vulnerability

Hackers know they want to corrupt your wireless network, and it doesn’t
take too long once they gain physical access to your corporate offices.
It is common that a cleaning staff person can actually be a hacker who
needs only a few minutes alone in your network room to destroy cabling,
install a virus onto the server, fray the cables (causing intermittent connectivity),
or simply pour water onto your computing devices.

The best defense against physical vulnerabilities is to keep access to
any room with WLAN equipment away from everyone except authorized
personnel who are supposed to be working in this equipment. You
should always place access points and associated antennae in a secured
area that is nowhere near public places. You should then protect this equipment by placing the machines in locked rooms with barriers and
access controls that prevent anyone from getting near this equipment.

You may also wish to install intrusion detection systems (IDSs) that
monitor activity near this equipment and watch these assets with
remote cameras used by special administrative personnel over the Internet
(through a secure channel!) or at a remote office location so that you
know who has been accessing your wireless equipment in an attempt to
gain unauthorized access.
