Network Security

This chapter guides you on how to protect your home network from unauthorized

users by implementing these three network security functions. You can block or allow

specific client devices to access your wireless network using MAC Filtering, or using

Access Control for wired and wireless networks, or you can prevent ARP spoofing and

ARP attacks using IP & MAC Binding.

MAC Filtering

This function exploits the uniqueness of the MAC (Medium Access Control) address,

a unique 12-digit hexadecimal address (for example, D8:5D:4C:B4:46:EA) of every

network device, to determine if the device can or cannot access your wireless network.

Prevent unauthorized users from accessing my wireless network

by utilizing the network device’s MAC address and IP address.

For example

, I have a computer that is connected to my wireless

network. Now, an unknown device (an intruder) is also using my

wireless network, which affects my Internet speed. I would like

to control my wireless network with the following capabilities:

• My computer is always allowed to access the wireless network.

• The unknown device is not allowed to access the wireless

network.

• I don’t have to keep changing my wireless password as often.
