IRL Security
IRL refers to “in real life” security; while most hacker attacks occur on
the “ether” of the net, IRL security refers to physical security dealing
with the actual nuts and bolts of your system. The concept of protecting
these resources is as real as any other element of your system security.
The tangible portions of your physical network can be damaged in
any number of ways, not the least of which is sabotage. Wireless networks
have all the same types of problems that any radio station
endures. Lightning strikes can disrupt your equipment and cause
irreparable damage.
Access points are essentially radio transmitters, so it is important to
ground all your equipment and locate the antennas in areas that are not
near the outside areas of your building.
Hackers may see exposed antenna arrays as an easy way to reverse
transmit radio signals through the antennas in an attempt to destroy
the wireless transmitter in your equipment. In fact, most radio transmitter
assemblies can be tweaked to transmit 100 watts of power into a
transmitting antenna. The purpose of this action is to destroy your
transmitter and your WLAN. This is easy to do if any portion of your
radiating assembly is in an unsecured area that a hacker can access.
