Sicherheits Standards im Wireless LAN

• SSID -> WlanSicherheit (802.11b Konfiguration)
• MAC -> WlanSicherheit (802.11b Konfiguration)
• WEP
• LEAP
• EAP
• IeEE8021x - To address WEP security flaws, the IEEE came up with IEEE 802.1X standard. This was widely implemented in the late 2001 and throughout 2002 by wireless LAN manufacturers.
  • The IEEE 802.1X standard, a framework designed to provide controlled port access between wireless client devices, access points and servers. It employs dynamic keys instead of the static keys used in WEP authentication, and it requires an authentication protocol for mutual authentication. For authentication to work, the user's transmission must go through a wireless LAN access point to reach the remote authentication dial-in user service (RADIUS) backend server performing the authentication.
• IeEE80211i - IEEE 802.11i is a security standard expected in late 2003 that will further the authentication and encryption gains implemented by WPA. Most notably, it will add a ground up encryption standard known as advanced encryption standard (AES) as well as other enhancements.
• WPA - Wi-Fi Protected Access (WPA) is being deployed in wireless LAN products as a standard feature and vendors are making this protection available with a software download.
  • WPA implements the encryption benefits of temporal key integrity protocol (TKIP). TKIP was built upon the WEP standard and was designed and scrutinized by top cryptographers to further bolster the protection offered to WLAN networks.
