Section 4 - Security

Wireless Security

This section will show you the dierent levels of security you can use to protect your data from intruders. The DAP-1533 oers

the following types of security:

• WPA2 (Wi-Fi Protected Access 2) • WPA2-PSK (Pre-Shared Key)

• WPA (Wi-Fi Protected Access) • WPA-PSK (Pre-Shared Key)

What is WPA?

WPA, or 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 computer’s 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 bridge or access point.

WPA/WPA2 incorporates user authentication through the Extensible Authentication Protocol (EAP). EAP is built on a more

secure public key encryption system to ensure that only authorized network users can access the network.
