Editing AirPort (section)

==Security==
AirPort and AirPort Extreme support a variety of security technologies to prevent [[eavesdropping]] and unauthorized network access, including several forms of [[cryptography]].

The original graphite AirPort base station used 40-bit [[Wired Equivalent Privacy]] (WEP). The second-generation model (known as Dual Ethernet or Snow) AirPort base station, like most other [[Wi-Fi]] products, used 40-bit or 128-bit [[Wired Equivalent Privacy]] (WEP). AirPort Extreme and Express base stations retain this option, but also allow and encourage the use of [[Wi-Fi Protected Access]] (WPA) and, as of July 14, 2005, [[WPA2]].

AirPort Extreme cards, which use the [[Broadcom]] chipset, have the [[media access control layer]] in software. The driver is [[closed source]].
