The hacker can use such information to do long-term traffic profiling and analysis that may provide user or device details. To mitigate such hacker activities, a site should use per-session WEP keys. A Complete Security Solution What is needed is a wireless LAN security solution that uses a standards-based and open architecture to take full advantage of 802.11b security elements, provide the strongest level of security available, and ensure effective security management from a central point of control. A promising security solution implements key elements of a proposal jointly submitted to the IEEE by Cisco Systems, Microsoft and other organizations. All sensitive information, such as the password, is protected from passive monitoring and other methods of attack.
Nothing is transmitted over the air in the clear.
A wireless client associates with an access point. The access point blocks all attempts by the client to gain access to network resources until the client logs on to the network. The user on the client supplies a username and password in a network logon dialog box or its equivalent. One of several authentication methods or types can be used. The client loads this key and prepares to use it for the logon session.
