Configuring AP Security

The Default AP profile does not use any security mechanism by default. In order to protect your network, D-Link strongly
recommends that you select a security mechanism so that unauthorized wireless clients cannot gain access to your network.
From the VAP tab of the Wireless Network Configuration page, you can select None, WEP or WPA/WPA2 as the WLAN
security mechanisms, as the following figure shows. The default is None.
The following sections describe the security mechanicians.
Using No Security
If you select None as your security mode, no further options are configurable on the AP. This mode means that any data
transferred between the AP and the associated wireless clients is not encrypted, and any wireless client can associate with
the AP.
This security mode can be useful during initial network configuration or for problem solving, but it is not recommended for
regular use on the internal network because it is not secure.
Using Static or Dynamic WEP
Wired Equivalent Privacy (WEP) is a data encryption protocol for 802.11 wireless networks. If you select this security
mechanism, all wireless clients and access points on the network are configured with a 64-bit (40-bit secret key + 24-bit
initialization vector (IV)) or 128-bit (104-bit secret key + 24-bit IV) Shared Key for data encryption.
Static WEP is not the most secure mode available, but it offers more protection than setting the security mode to None as
it does prevent an outsider from easily sniffing out unencrypted wireless traffic.
Dynamic WEP is more secure than Static WEP, but you need a RADIUS server to manage the dynamically generated keys.
WEP encrypts data moving across the wireless network based on a static key. (The encryption algorithm is a stream cipher
called RC4.)
