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.

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.

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 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 an 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 head end 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.

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.

Abstract: Apparatus for recording and collecting usage and other statistical data from components of a cable data network comprises a network manager for maintaining and collecting the statistics. Internet protocol addresses are associated with components of the network. The component maintains a software agent that manages a statistics database. Responsive to a manager request generated at a service provider defined time interval, the component software agent provides the usage statistics to the network manager in real-time during an Internet session with a host. When the host to Internet or other data connection is torn down due to failure, disconnect or inactivity time-out, remaining usage statistics data is collected and the session duration updated with the time of tear down.

Abstract: The problem of wasting IP addresses by statically assigning them to hosts is solved as follows: when a cable router or RF modem becomes active, it sends a message requesting a set of IP addresses from the head end, which dynamically assigns the set of IP addresses and sends a message comprising the set of IP addresses to the cable router or RF modem. The cable router or RF modem then responds to requests by the hosts for IP addresses by assigning them IP addresses from the set. Furthermore, the set of IP addresses is released when the session terminates with the cable router or RF modem.
