The location of your wireless access points is the first layer of security for your wireless network. If your wireless access points can be physically affected by a passerby, you’re in big trouble.
The easiest way to hack a wireless access point is to walk up to it and press the reset button. This will default to an open network and you will have the keys to the kingdom.
When placing your wireless access point, the only thing you should be able to see is perhaps the antenna. You can buy access point antennas that look like roof panels or fire alarms.
If a hacker is in your building testing your wireless network, they will look for access points. If you can determine the make and model of your access point, you can search the Internet for default passwords and vulnerabilities for that access point.
Finally, when placing your wireless antennas outdoors, try to have them blend in with the building as much as possible. You should use a wireless directional antenna that sits flat against a wall instead of a Yagi antenna that screams look at me.
Wireless access points can be hacked in 20 seconds or less if they are mounted in the wrong place. The most secure wireless network is the one that no one knows about.
