摘要： A method for monitoring a selected region of an airspace associated with local area networks of computing devices is provided. The method includes providing one or more segments of a legacy local area network to be protected in a selected geographic region. The legacy local area network is characterized by an unsecured airspace within the selected geographic region. The method includes determining a security policy associated with the one or more segments of the legacy local area network. The security policy at least characterizes a type of wireless activity in the unsecured airspace to be permitted, denied, or ignored. Additionally, the method includes connecting one or more sniffer devices into the legacy local area network. The one or more sniffer devices are spatially disposed within the selected geographic region to cause at least a portion of the unsecured airspace to be secured according to the security policy. Moreover, the method includes coupling a security appliance to the legacy local area network. The method also includes determining if at least one of the sniffer devices is coupled to each of the one or more segments of the legacy local area network to be protected and determining if the one or more sniffer devices substantially covers the portion of the unsecured airspace to be secured The method additionally includes monitoring wireless activity in the airspace using the one or more sniffer devices, and automatically classifying, using a classification process, a portion of information associated with the monitoring of the wireless activity to at least determine if the wireless activity communicates to at least one of the one or more segments to be protected. Further, the method includes detecting a violation of the security policy based upon at least the classifying of the portion of the information from the monitoring of the wireless activity, and automatically processing an action associated with the violation in accordance to the security policy for the one or more segments in the legacy local area network to be protected

摘要： A method of estimating a location of a wireless device providing a wireless attack. The method includes disposing a number of sniffers in a geographic region and receiving a number of wireless signals at one or more of the number of sniffers. The method also includes processing the number of wireless signals to identify a subset of the number of wireless signals that are associated with the wireless device and determining a number of received signal strengths associated with the subset of the number of wireless signals. The method further includes providing an estimation of the location of the wireless device utilizing the determined received signal strengths associated with the subset of the number of wireless signals.

摘要： A method for disrupting unauthorized communications between at least two communication devices is provided. The method comprises using an address resolution protocol (ARP) to redirect transfer of data that occurs using unauthorized wireless communication between a first wireless device and a second wireless device. In a preferred embodiment, the method maintains a layer two wireless link while the data are being redirected.
