Getting To Know AG-3621 Wireless Security Options
Zcomax (UK) Limited wants to make wireless networking as safe and easy for you as possible.
The current generation of Zcomax (UK) Limited products provides several network security
features, but they require specific action on your part for implementation. So, keep the
following in mind whenever you are setting up or using your wireless network.
Security Precautions
The following is a complete list of security precautions to take as shown in this User’s Manual.
(at least steps 1 through 5 should be followed):
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, at least. Wireless
networks are easy to find. Hackers 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 AG-3621. 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. The very strong authentication along with dynamic per frame re-keying of WPA
makes it virtually impossible to compromise.
