Ways to Secure Your Wireless Network

View recommendations and suggestions to further secure your wireless home network.
The following table provides several different methods that you can take to better secure your wireless network. Both recommendations and suggestions are included.
|Enable high level of encryption|
There are several encryption methods that can be used to secure a wireless network. Depending on the age and type of your device you may have one or more encryption methods at your disposal.
Recommend: Enable WPA encryption.
|Enable some level of encryption when WPA is not available|
If you find that some of your wireless devices only support Wired Equivalent Privacy (WEP) encryption, like Media Players, Personal Digital Assistants (PDAs), and Digital Video Recorders (DVRs), it is still important to enable encryption.
Recommend: Enable WEP encryption as some encryption is better than no encryption.
In spite of the issues with using WEP encryption, it is still better than having no encryption at all. When using WEP, use an encryption key that is extremely hard to guess. Refrain from using a WEP key like a string of the same or consecutive numbers. Because of the security issues, when using WEP encryption it is also highly advisable to change the encryption keys often. Additionally, when using WEP encryption, enabling Media Access Control (MAC) filtering can provide another ‘layer’ of protection (See ‘Turn on MAC filtering’ below).
|Create a strong admin password|
Many devices have an Administrator username and password that are needed to access the device and modify any configuration settings. Most of these devices use a weak default password while others do not have a default password at all.
|Turn off remote administration|
Most wireless devices have the ability to be remotely operated or administered via the Internet. This feature can allow almost anyone to find and access the settings for your device.
|Save your configuration|
Many devices have the ability to save a file containing your device configuration to a location on your network.
|Turn off broadcasting|
Many devices automatically (and continuously) broadcast the network's name, or SSID. This makes setting up wireless clients extremely convenient since you can locate a Wireless network without having to know what it is called. The drawback to this is that this also makes your Wireless network visible to any wireless devices within range.
|Turn on MAC filtering|
Another security measure that should only be used with encryption is MAC address filtering. MAC addresses are unique to specific network adapters and devices so by enabling MAC address filtering you can manage access to your network.
Using MAC address filtering requires that you manually enter the 12-character MAC address of every device that will be managed on your network. If you frequently add new devices to your network, MAC address filtering can become inconvenient and time consuming.
