Wireless Security
This section will show you the dierent levels of security you can use to protect your data from intruders. The router oers wireless security options
like WPA/WPA2 PSK/EAP.
What is WPA?
WPA (Wi-Fi Protected Access), is a Wi-Fi standard that was designed to improve the security features of WEP (Wired Equivalent Privacy).
The 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 computers hardware-specic MAC address, which is relatively simple to be snied 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 uses a passphrase or key to authenticate your wireless connection. The key is an alpha-numeric password between 8 and 63
characters long. The password can include symbols (!?*&_) and spaces. This key must be the exact same key entered on your wireless router or
access point.
