| 20090019531 | SYSTEM AND METHOD FOR WIRELESS LOCAL AREA NETWORK MONITORING AND INTRUSION DETECTION - Systems and methods for providing improved network security against unauthorized wireless devices are presented. A security component within in a wired portion of a computer network is provided. The security component is configured to control the bridging of network activity between the wireless portion and wired portion of the computer network. Using the security component, network traffic between the wireless and wired portions of the computer network for unknown wireless devices is passively monitored. Upon network traffic between the wireless and wired portions of the computer network for an unknown wireless device, the security component determines at least one identifying characteristic of the unknown wireless device by actively probing the device for an identifying characteristic. The security component determines at least one behavioral characteristic of the device according to the network traffic between the device and devices in the wired portion of the computer network. A device profile for the unknown wireless device is generated according to the identifying and behavioral characteristics, access privileges corresponding to the unknown wireless device according to the device profile are determined, and network traffic from the unknown wireless device is permitted to pass to the computer network according to the determined access privileges. | 01-15-2009 |
