Wireless Security Configuration
Establishing Security
Web: Setting Security Options
The Security tab provides these options:
■
No Security: The access point is configured as an open system with no
user authentication or data encryption. This is the default setting.
■ Static WEP: Use static IEEE 802.11 Wired Equivalent Privacy (WEP)
shared keys for user authentication and data encryption. Four keys can
be defined for each WLAN interface that uses static WEP, but only one of
these WEP keys is transferred for active use by the SSID interface at any
given time. Note that the same WEP key must be used by each station
associated with the SSID interface.
• Transfer Key Index: Select the key number (1–4) to use for encryp-
tion of transmitted data. The selected index must not be already
allocated to another SSID interface. (The default is 1.)
• Key Length: Select 64 bits or 128 bits. Note that the same size of
encryption key must be supported on all wireless stations. (The
default is 128 bits.)
•
Key Type:
Select the preferred method of entering WEP encryption
keys on the access point and enter up to four keys:
–
ASCII: Enter keys as 5 alphanumeric characters for 64-bit keys
or 13 alphanumeric characters for 128-bit keys.
– Hex: Enter keys as 10 hexadecimal digits for 64 bit keys or 26
hexadecimal digits for 128 bit keys. (The default is Hex.)
• WEP Keys: Enter up to four strings of character keys. If you selected
“ASCII”, enter any combination of ASCII characters. If you selected
“Hex”, enter hexadecimal digits (any combination of 0–9 and a–f or
A–F). The number of characters required is updated automatically,
based on how you set Key Length and Key Type.
• [Update]: Updates the security parameters.
N o t e
■
When static WEP is selected, the AP530 uses “Open” authentication.
■ WEP has been found to be seriously flawed and cannot be recommended
for a high level of network security. For more robust wireless security, the
access point provides Wi-Fi Protected Access (WPA) for improved data
encryption and user authentication.
■
Dynamic WEP: Establishes the Extensible Authentication Protocol
(EAP) to pass user credentials from the station to the RADIUS server.
Authentication is then verified on the RADIUS server before the access
point grants station access to the network. For the configuration of the
RADIUS servers, see
“Web: Setting RADIUS Server Parameters” on page 7-33
.
• RADIUS Servers: Opens the RADIUS configuration screen.
