Summary

Summary

This chapter described the requirements for security on wireless networks in terms of authentication, data confidentiality (encryption), and data integrity. The original 802.11 standard defined two types of authentication (open system and shared key) and WEP, which provides encryption and data integrity. The security methods used by the original 802.11 standard proved to be relatively weak and did not scale for large wireless networks. The 802.1X standard was adapted for 802.11 wireless networks to provide much stronger authentication and automated encryption key management. WPA, a software upgrade for wireless equipment, replaces WEP encryption with TKIP and WEP data integrity with Michael. Using 802.1X, WPA, or both can mitigate the most common attacks against wireless networks.
