3-2 Wireless Security Options
To make wireless networking as safe and easy as possible, this radio provides several
network security features, but requires specific programming and setup.
Security Precautions
The following is a complete list of recommended security precautions that can be taken to
help ensure a secure network.
1. Change the default SSID.
2. Disable
SSID
Broadcast.
3.
Change the default password for the Administrator account.
4.
Enable MAC Address Filtering.
5. Change
the
SSID
periodically.
6. Use the highest encryption algorithm possible. Use WPA if it is available. Please note
that this may reduce your network performance.
7. Change the WEP encryption keys periodically.
To ensure network security, steps one through four should be followed.
Wireless
networks are easy to find. Unauthorized users know, that in order to join a wireless
network, wireless networking products first listen for “beacon messages”. These
messages can be easily decrypted and contain much of the network’s information, such
as the network’s SSID (Service Set Identifier).
Security Options
There are several ways you can enhance the security of your wireless network:
Restrict Access Based on MAC address.
You can restrict access to only trusted clients so
that unknown clients cannot wirelessly connect to the radio. MAC address filtering adds
an obstacle against unwanted access to your network, but the data broadcast over the
wireless link is fully exposed.
Use WEP.
Wired Equivalent Privacy (WEP) data encryption provides data security. WEP
Shared Key authentication and WEP data encryption will block all but the most
determined eavesdropper.
Use WPA or WPA-PSK.
Wi-Fi Protected Access (WPA) data encryption provides data
security. A very strong authentication key along with dynamic per frame re-keying of WPA
makes it virtually impossible to compromise.
Enable Wireless Security Separator.
The associated wireless clients will not be able to
communicate with each other if this feature is enabled. The default setting is
disabled.
