Wireless Security; What Is Wpa - D-Link DSL-X1852E User Manual

Appendix B - Networking Basics
This section will show you the different levels of security you can use to protect your data from intruders. The DSL-X1852E offers the
following types of security:
• WPA2/WPA with 802.1x (Wi-Fi Protected Access 2)
(Wired Equivalent Privacy)
• WEP
WPA (Wi-Fi Protected Access), is a Wi-Fi standard that was designed to improve the security features of WEP (Wired Equivalent
Privacy). WPA has 2 major improvements over WEP:
• Improved data encryption through the Temporal Key Integrity Protocol (TKIP). TKIP scrambles the keys using a hashing
algorithm and by adding an integrity-checking feature, ensures that the keys haven't been tampered with. WPA2 is based
on 802.11i and uses Advanced Encryption Standard (AES) instead of TKIP.
• User authentication, which is generally missing in WEP, through the Extensible Authentication Protocol (EAP). WEP regulates
access to a wireless network based on a computer's hardware-specific MAC address, which is relatively simple to be sniffed
out and stolen. EAP is built on a more secure public-key encryption system to ensure that only authorized network users
can access the network.
WPA-PSK/WPA2-PSK/WPA3-SAE uses a passphrase or key to authenticate your wireless connection. The key is an alpha-numeric
password between 8 and 63 characters long. This key must be the exact same key entered on your wireless router or access
point. Further, the Simultaneous Authentication of Equals (SAE) of WPA3 enhances the protection against dictionary attacks.
WPA3-SAE has the strongest encryption among these with the increased cryptographic capability and the requirements of the
Protected Management Frames (PMFs) to help prevent snooping attacks.
The WPA2/WPA with 802.1x option features WPA2/WPA used in coordination with a RADIUS server for user authentication in an
organization or enterprise environment. The exchange of authentication information between wireless clients and a RADIUS
server employs Extensible Authentication Protocol (EAP).
