  • Patent number: 9003527
    Abstract: The wireless activity in a geographic area containing LAN connection ports is monitored using one or more sensor devices, called sniffers. By analyzing said wireless activity, one or more APs that are operating in said geographic area are identified. The active APs so identified are classified into three categories, namely “authorized” APs (those that are allowed by network administrator), “unauthorized” APs (those that are not allowed by the network administrator, but are still connected to the LAN of interest) and “external” APs (those that are not allowed by network administrator but are not connected to the LAN of interest, for example APs connected to the neighbor's LAN) by conducting one or more tests. The sniffers detect any wireless station attempting to connect to or communicating with the one or more identified unauthorized APs. Upon identifying unauthorized AP and/or intruding wireless station an indication is transferred to the prevention process.

  • Publication number: 20110083165
    Abstract: A method for restricting one or more wireless devices from engaging in wireless communication within a selected local geographic region. The method includes receiving an indication comprising at least identity information. Preferably, the indication is associated with a selected wireless device, which is associated with an undesirable wireless communication within the selected local geographic region. The method includes selecting one or more processes directed to restrict the selected wireless device from engaging in wireless communication and performing a prioritized access to a wireless medium using at least one of one or more sniffer devices, which are spatially disposed within a vicinity of the selected local geographic region. The method transmits one or more packets from the at least one of one or more sniffer devices. Preferably, the one or more packets are directed to perform said one or more processes to restrict the selected wireless device.

    Abstract: Methods and systems for detecting a masquerading wireless device in a local area network are provided. The method includes receiving a first packet and a second packet. Preferably, the first packet includes a first identity information and a first time information, and the second packet includes a second identity information and a second time information. The method can compute, using the first time information, a first approximation to a starting time of a wireless device associated with the first identity information. The method can also compute, using the second time information, a second approximation to a starting time of a wireless device associated with the second identity information. The method further includes determining whether a masquerading wireless device is present in the local area network based on at least the first and second approximations.

    Abstract: 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.
