and also may be the right convenience trade-off for other scenarios where the priority is making it as
easy as possible for clients to connect. (See “Does Prohibiting the Broadcast SSID Enhance Security?
”)
Following is a brief discussion of what factors make one mode more secure than another, a description
of each mode offered, and when to use each mode.
Comparison of Security Modes for Key Management,
Authentication and Encryption Algorithms
Three major factors that determine the effectiveness of a security protocol are:
How the protocol manages keys
Presence or absence of integrated user authentication in the protocol
Encryption algorithm or formula the protocol uses to encode/decode the data
Following is a list of the security modes available on the AT-TQ2403 Management Software
along with a description of the key management, authentication, and encryption algorithms used
in each mode. We include some suggestions as to when one mode might be more appropriate
than another.
When to Use Unencrypted (No Security)
When to Use Static WEP
When to Use IEEE 802.1x
When to Use WPA Personal
When to Use WPA Enterprise
When to Use Unencrypted (No Security)
Setting the security mode to None (Plain-text) by definition provides no security. In this mode, the
data is not encrypted but rather sent as "plain-text" across the network. No key management, data
encryption or user authentication is used.
Recommendations
Une
ncrypted mode, i.e. None (Plain-text), is not recommended for regular use on the Internal
network because it is not secure. This is the only mode in which you can run the Guest network, which
is by definition an insecure LAN, always virtually separated from any sensitive information on the Internal
LAN.
Therefore, only set the security mode to None (Plain-text) on the Guest network, and on the Internal
network for initial setup, testing, or problem solving only.

When to Use Static WEP
Static WEP (Wired Equivalent Privacy) is a data encryption protocol for 802.11 wireless networks. All
wireless stations and access points on the network are configured with a static 64-bit (40-bit secret key
