Replacement Of WEP
| | Why do you need replacement of WEP? Check here what is WPA and the best WEP replacement. |
If you ask me is it better to use WEP or to have no security at all on your wireless network, I would say use WEP. But in wireless networks today, WEP is not enough. Your network is very vulnerable with WEP, check on WEP key find in less than a minute. There are two versions of WEP (Wired Equivalent Privacy), one version is using 64-bit shared key and other is WEP with 128-bit shared key. Read about WEP, its main weaknesses and the structure of the WEP shared-key on WEP open or shared. I do not recommend WEP not only in an enterprise environment, but also in your home networks. The reason for that is that all new WLAN equipment supports WPA. The majority of old WLAN equipment, you could make WPA compatible, only with a simple upgrade of drivers on your PC and firmware on your broadband wireless router or access point. On the WEP vs WPA you could read about the weaknesses of the WPA and the advantages of WPA over WEP. WEP can be replaced with WPA TKIP (Temporary Key Integrity Protocol). TKIP is also backward compatible with WEP. TKIP is not perfect, but it is good enough for your home network. For enterprise networks that could afford RADIUS server, use WPA and WPA2 Enterprise. There are four versions of a WPA security: 1) WPA-Personal mode - use PSK authentication and TKIP/MIC encryption 2) WPA-Enterprise mode - use authentication 802.1x/EAP and TKIP/MIC encryption 3) WPA2-Personal mode - with 802.1x/EAP authentication and AES/CCMP encryption 4) WPA2-Enterprise mode – with PSK authentication and AES/CCMP encryption.
To learn more about the WPA, the authentication and encryption mechanism and its implementation read on What is WPA.
