Wireless 101

A Few Words About Security

Security for WLANs continues to evolve. The newest standards offer a very high level of encryption to protect data transfers. Here are some wireless security basics.

WEP (Wired Equivalent Privacy) | This security protocol for WLANs encrypts data over radio waves, protecting it in transit. Advocates originally believed WEP provides the same level of protection as a wired LAN, but recently the standard was found to have security holes.

WPA (Wi-Fi Protected Access) | Designed to compensate for the shortcomings of the WEP security standard, WPA ensures that only authorized users can access the network. The technology works with WEP-enabled products, and adds improved encryption, while allowing user authentication through the extensible authentication protocol (EAP). EAP is built on a highly secure public encryption system.

802.11i | This security protocol, recently ratified under IEEE's all encompassing 802.11 banner, will eventually replace the interim WPA security standard. 802.11i bolsters protection by using Advanced Encryption Standard, which is so difficult to crack that it meets government security standards. Wireless access points have begun shipping with 802.11i installed.
