Electronic House Expo/Fall 2001 Long Beach S59: Installing Wireless - The Configuration Choices Gateways offer Firewall Security But Power Line & RF extend Outdoors, Internet Ethernet HomePNA or HomePlug so beware of Compromises! Gateways let users share their Internet connection, and Firewalls provide security from hackers. Both Ethernet and Phone Line wiring are fairly secure since attacks require physical access. But Power Lines and RF extend outside for long distances. Serious security holes in Wi-Fi have been well publicized, and defeating WEP security is trivial with off-the-shelf products. HomeRF offers an extra layer of security that is especially important to consumers with no IT support personnel to protect them. (Details on next slide)
