Protokol 802.11i pomohl bezpe?nosti Wi-Fi sítí, ale není všelék, ?íkají jejich vývojá?i30.09.2004
The 802.11i protocol has been praised as a Wi-Fi suit of armor. But two people who had a hand in its development warn that wireless networking is still vulnerable to attack and that extra precautions are necessary.
Approved by the IEEE in June, 802.11i is designed to better encrypt data sent along a Wi-Fi-established WLAN and ensure it can't be cracked if intercepted. While Moskowitz and Walker touted those improvements, they warned wireless technology remains vulnerable to break-ins, forgeries, data exposure and other threats and offered users advice on how to make their networks more ironclad.
Walker also warned that technology doesn't work if security goals aren't clearly understood. "You can't just talk about pie-in-the-sky security," he said. "You need specific goals. If your biggest concern is forgery, your goals must revolve around stopping forgery." He added that enterprises should have their security plans reviewed by outside parties.
