5.4 Security on the Wireless Network
In a wireless network, data security is maintained using the following three functions.
According to your security needs, use any combination of these security options and
strengthen your security.
SSID
(
Page 83)
SSID (Service Set IDentifier) is a wireless network name.
SSID setting must be same among the wireless devices.
For security, specify a unique SSID that others
cannot guess for a wireless network. Avoid an obvious
SSID (your name, birthday, etc.), since the communication
may be interfered with the neighbor wireless network.
Advantage:
It is easy to set the SSID into each wireless device.
Disadvantage:
If an unauthorized user steals the SSID, he may break into
wireless networks.
Encryption
(
Page 86)
This setup allows you to encrypt the data that is transmitted
over your wireless network. By setting a WEP key in the
KX-HGW600, you can prevent wireless network data from
being decrypted externally. To read an encrypted file, the
same WEP key must be set into each wireless device. There
are two types of WEP key, 40(64) bit and 128 bit versions.
Advantage:
The higher the bit number, the more secure the encryption.
Disadvantage:
The higher the bit number, the slower the communication
speed.
MAC Address
Filtering
(
Page 91)
If the MAC address on each wireless network card has not
been registered on the MAC Address Filtering window, the
wireless devices cannot link to the KXHGW600.
Advantage:
Even if SSID or WEP key is stolen by an unauthorized
user, the wireless devices with unregistered MAC address
cannot communicate with the KX-HGW600.
Disadvantage:
The greater the scale of wireless network is, the more
vexatious the administration of MAC addresses may be.
