Abstract: In one embodiment, the present invention is a method and apparatus for identifying wireless transmitters. In one embodiment, a method for identifying a transmitter in a wireless computing network includes extracting one or more radio frequency signal characteristics from a communication from the transmitter and generating a fingerprint of the transmitter in accordance at least one of the extracted radio frequency signal characteristics.

Abstract: In one embodiment, the present invention is a method and apparatus for wireless network security. In one embodiment, a method for securing a wireless computing network includes receiving a communication from an unidentified transmitter, identifying the transmitter in accordance with a fingerprint generated from one or more radio frequency signal characteristics extracted from the communication, and taking action in response to an identity of the transmitter.

Abstract: A groupware management system for collaborative groups is disclosed that is scalable to support large, dynamic, multiple, and other virtual VPNs. The system may introduce a graph (or hierarchical) structure to the VPN, providing multiple master nodes controlling membership in subsets of the collaborative group. Use of multiple master nodes in a graph-structured (or hierarchical) network topology often relaxes the need for a single, centralized, globally consistent view of VPN group membership, and enables distribution of the management burden among multiple master nodes. Membership in the VPN may be changed dynamically by the second master node for the member nodes of the second subset, without requiring the first master node to dynamically update its group membership records to reflect the change and in many cases without even having to notify the first master node (and vice versa), for example.

Abstract: A method includes passing a request for data received by a first server process executing in a first server to a detection process that includes packing a subset of the data into an analysis format and passing the subset to an analysis process.
