Is wireless communication secure?

Wireless networks can be "tapped" in a similar manner to a wired network. That is why it is important to implement encryption as a standard security measure on all wireless networks. Some wireless networks allow for MAC address filtering which is, in effect, an access list that allows only certain computers on a network. This is an added effective step to protect intrusions on home networks. See the links on the Vendor specific How-Tos page for additional information.
