Open Mode It allows any device to join the network without
performing any security check.
Shared Mode Data encryption and key are required for wireless
authentication.
WEP Mixed Mode WEP (Wired Equivalent Privacy), a basic encryption
method, usually encrypts wireless data using a series
of digital keys (64 bits or 128 bits in length).
By using the same keys on each of your wireless
network devices, you can prevent unauthorized
wireless devices from monitoring your transmissions
or using your wireless resources. WEP is based on
RSA algorithm from RC4. It is the original and weak
encryption method, so it is recommended not to use
this method.
WPA-Enterprise With warrant (username, password and etc.) offered
by user, this kind of authentication can be realized with
specific RADIUS server. This is the common way to be
adopted in large enterprise network.
WPA2-Enterprise You can use a RADIUS server to authenticate wireless
stations and provide the session key to encrypt data
during communication. It uses TKIP or CCMP (AES) to
change the encryption key frequently.
Mixed
WPA/WPA2-Enterprise It provides options of WPA (TKIP) or WPA2 (AES) for
the client. If it is selected, the data encryption type
must be TKIP + AES and the RADIUS server must be
set.
802.1X This security mode is used when a RADIUS server is
connected to the device. 802.1x, a kind of Port-based
authentication protocol, is an authentication type and
strategy for users. The port can be either a physic port
or logic port (such as VLAN). For wireless LAN users,
a port is just a channel.
The final purpose of 802.1x authentication is to check
if the port can be used. If the port is authenticated
successfully, you can open this port which allows all
the messages to pass. If the port isn’t authenticated
successfully, you can keep this port “disable” which
just allows 802.1x authentication protocol message to
pass.
