Wireless

Wireless technologies seem to be growing quickly. Just turn on your laptop and drive through any neighborhood and the laptop will invariably find wireless computer networks, some with security and many without.

Wireless equipment almost always works right out of the box, in the true plug and play modality. The warning here is that these devices often have even rudimentary security disabled in their default configuration.

Remember, default=works easily=NO security!

Security of Wireless

Security of wireless connections falls into 2 categories: WEP and WPA.

WEP, or wired equivalency privacy, is a 64 or 128 bit encryption, with a manually assigned static key and it uses no authentication. The key is sent in every packet, so with the right equipment, you can capture enough packets and crunch out the key, thereby compromising the network security.

WPA, or wifi protected access, is better than WEP. It uses dynamic, unique keys, requires authentication and is more difficult to implement; all equipment using WPA must natively support it and it is more hardware intensive, so the equipment itself is inherently more expensive.

WPA2, or Wi-Fi protected Access 2 is the name for wireless security that adheres to the 802.11i specifications. This technology is best of class and requires more powerful equipment for securing your wireless network.
