What Is Wi-Fi Protected Access (Wpa); What Is Wpa2; What Is 802.1X Authentication; What Is Temporal Key Integrity Protocol (Tkip) - Planet WNAP-6350 User Manual

15. What is Wi-Fi Protected Access (WPA)?
W i-Fi's original security mechanism, Wired Equivalent Privacy (WEP), has been viewed as insufficient for
securing confidential business communications. A long
development. However, since the IEEE 802.11i standard is not expected to be published until the end of 2003,
several members of the WI-Fi Alliance
s ignificant near-term enhancement to Wi-Fi security. Together, this team developed Wi-Fi Protected Access.
To upgrade a WLAN network to support WPA, Acc
require a software upgrade for the network interface card, and possibly a software update for the operating
system. For enterprise networks, an authentication server, typically one that supports RADIUS and the selected
EAP authentication protocol, will be added

16. What is WPA2?

It is the second generation of WPA. WPA2 is based on the final IEEE 802.11i amendment to the 802.11
standard.
17. What is 80 2.1x Authentication?
8 02.1x is a framework for authenticated MAC-level access control, defines Extensible Authentication Protocol
(EAP) over LANs (WAPOL). The stand
dial-up authentication with Point-to-Point Protocol in RFC 2284.
Beyond encapsulating EAP packets, the 802.1x standard also defines EAPOL messages that convey the shared
key information critical for wireless security.

19. What is Advanced Encryption Standard (AES)?

Security issues are a major concern for

20. What is Inter-Access Point Protocol (IAPP)?

The IEEE 802.11f Inter-Access Point Protocol (IAPP) supports Access Point Vendor interoperability, enabling
