Wireless networks are rapidly becoming more
popular and down in price. Since they don’t
require cables, you can use the devices
anywhere in an office or home. There’s no
need to roll out an Ethernet network cable;
you can network anywhere without wires.
Wireless networking makes it easy to share
data and Internet access. With a wireless
network, your information is traveling through
the airwaves—not physical wires, so anyone
within range can "listen in" on your network.
Here are four essential security measures you should take to secure your wireless network.
1. Change the default SSID (network name).
2. Disable the SSID broadcast option.
3. Change the default password needed to access a wireless device.
4. Enable MAC address filtering.
