  • Patent number: 7779476
    Abstract: A wireless network security system including a system data store capable of storing network default and configuration data, a wireless transmitter and a system processor. The system processor performs a network security method. An active defense request signal is received, typically from an intrusion detection system. The received request signal includes an indicator of an access point within the wireless computer network that is potentially compromised. In response to the received an active defense of the wireless network is triggered. The triggered active defense may be on or more of transmitting a jamming signal, transmitting a signal to introduce CRC errors, transmitting a signal to increase the difficulty associated with breaking the network encryption (typically by including in the signal packet appearing legitimate but containing randomized payloads, or transmitting a channel change request to the potentially compromised access point.

  • Patent number: 7532895
    Abstract: Wireless devices are adaptively tracked utilizing a system data store, a set of one or more wireless receivers, and a system processor. The system processor identifies a wireless device for tracking based on behavior through a combination of dynamic operational and security assessments derived using data from the system data store. It receives and stores data from a subset of the set of wireless receivers. It then calculates and outputs the position of the identified wireless device based upon the received data.

  • Patent number: 7355996
    Abstract: This application is directed to systems and methods for adaptive monitoring of a wireless network with bandwidth constraints. A data unit from a wireless node is received. When a bandwidth constraint is satisfied, the received data unit is buffered. When the bandwidth constraint is not satisfied, the received or buffered data unit is transmitted to a monitoring processor. In some instances, downsampling, data discard and data aggregation can occur during the buffering process.

  • Patent number: 7322044
    Abstract: The present invention is directed to systems and methods for automated detection of one or more wireless network policy violations and/or enforcement of such policies. A wireless network policy violation is detected. Associated with the detected violation are one or more wireless network attributes. A responsive corrective action is triggered which is based at least in part upon the detected violation, the associated wireless network attributes or combinations thereof. The corrective action can in some instances include a notification to a user or further system. In addition to, or instead of, a notification, the corrective action can include an attempt to configure one or more devices in the wireless network to correct, in whole or in part, the detected violation.

  • Patent number: 7296283
    Abstract: Apparatus for a cable television subscriber to log onto a computer network with a modem over an upstream path using a USERID and password. The network validates the subscriber USERID and subscriber password with a stored database of valid USERIDs and associated passwords. After the USERID and password are validated, the modem then provides it electronic serial number to the network for validation against a stored database of authorized serial numbers. Upon additional validation of the modem's serial number, the subscriber is authorized to use the network.

  • Patent number: 7099308
    Abstract: An asymmetrical network is disclosed for coupling customer-premises Internet hosts such as personal computers to the Internet. The head end of a CATV system has a high-bandwidth connection to the Internet. The CATV system supports a plurality of concurrent channels to which an RF modem is capable of tuning. The RE modem is capable of receiving information from the head end that specifies the channel to which the RF modem should tune. Once tuned to the specified channel, the RF modem is capable of utilizing the CATV system for carrying high-speed data traffic. The high-speed data traffic can support Internet access using the Internet Protocol (IP).

  • Patent number: 6922412
    Abstract: An asymmetrical network for coupling customer-premises Internet hosts such as personal computers to the Internet. The head end of a CATV system has a high-bandwidth connection to the Internet. The down link connecting the personal computers to the Internet is the cables provided by the CATV system; the up link is a telephone connection to the head end. A router is connected to the down link by means of a RF modem, to the up link by means of an analog modem, and to a LAN which is connected to the Pcs. The router routes IP packets for the hosts that are received on the CATV cable to the hosts via the LAN; it routes IP packets from the hosts that are destined for the Internet to the head end via the telephone line. The asymmetrical network conserves IP addresses and addresses on the CATV cable by dynamically allocating the IP addresses for an RF modem's hosts and an address on the CATV cable for the RF modem in response to a request made by the RF modem via the telephone line.

  • Publication number: 20040210654
    Abstract: The present invention is directed to systems and methods for wireless network topology mapping and/or analysis. Scan data associated with monitoring one or more wireless access points and/or one or more wireless network nodes is received. The received scan data, potentially in combination with other data such as access point and/or node characteristics, is used to identify one or more relationships between two access points, between two nodes and/or between an access point and a node. The identified relationships are stored and/or outputted. Some systems according to the present invention can implement the above processes on a system processor in communication with a system data store. Some such systems may further include a wireless receiver for monitoring wireless transmission and providing the scan data from such monitoring.

  • Publication number: 20040008652
    Abstract: A wireless network sensor includes a system data store capable of storing a variety of data associated with a wireless computer network and communication(s) transmitted thereon, a communication interface supporting at least reception of wireless communication(s) over the wireless computer network and a system processor. Data is extracted into one or more logical units or frames according to the protocol of the wireless network from signal received by the communication interface. This extracted data is inspected and stored. In some embodiments, the stored data is aggregated with information subsequently derived from further received signals. The stored data can be locally or remotely analyzed to generate a security rating which can be forwarded to either a user or a further data processing system.
