A technique for the detection of an unauthorized wireless communication device includes monitoring of Bluetooth&#xae; communications activity by a Bluetooth&#xae; capable communication device. Any monitored communication activity is analyzed against parameters that are predefined to detect suspected illegal activity. If illegal activity is suspected by the analysis, an alert is generated for a system administrator. The predefined parameters associate illegal activity with; data that includes credit card numbers and expiration dates, credit card transaction logging information, non-discoverable devices, activity after store hours, exceedingly long activity, etc.

Detection of an unauthorized wireless communication device

A technique for locating a wireless communication attack includes monitoring of Bluetooth&#xae; communications activity by a Bluetooth&#xae; capable communication device. Any monitored communication activity is analyzed against parameters that are predefined to detect a communication attempt by a suspected criminal device to an illicit device. If the communication attempt by the suspected criminal device is detected by the analysis, a communication to the criminal device is controlled so as to delay completion of the communication to the criminal device in order to provide time to locate the criminal device.

Locating a wireless communication attack

A technique for distributed propagation of data in a wireless communication network includes providinga unique host identifier for each peer network entity in the wireless communication network, each host identifier having a length of B bits. A next step includes requestingdata from peer network entities using a request having a host identifier of the requesting network entity. A next step includes, if a peer network entity is hosting the requested data, comparingthe host identifiers of the requesting network entity and the peer network entity receiving the request to determine a match. A next step includes respondingto the request if a match is determined.

Distributed propagation of data in a wireless communication network

A technique for synchronization of mobile device information in a wireless communication network includes associatinga mobile device (MD) to a first access point (AP). A next step includes transmittinga roam notification message from the first AP to all APs in network. A next step includes associatingthe MD to a second AP. A next step includes establishingthat the first and second APs are roaming neighbors. A next step includes buildinga roaming neighbor list in the associated first and second APs for the MD, wherein the list includes those neighboring APs where the MD has been associated. A next step includes determiningthat the MD is currently associated with an AP. A next step includes preemptively pushinginformation about the MD to those APs in the list of the determined AP for synchronization.

Synchronization of mobile device information in a wireless communication network

Apparatus and methods are provided for implementing a firewall in a network infrastructure component. A method comprises generating a search tree for a plurality of rules. The search tree comprises a first node having a first field bounds and a first set of rules of the plurality of rules, and a plurality of child nodes for the first node. Each child node has child field bounds based on an intersection of the first field bounds and the first set of rules, and each child node is assigned a respective subset of the first set of rules based on the respective child field bounds. The method further comprises receiving a first packet, identifying a first child node of the plurality of child nodes based on values for one or more fields of the first packet, and applying the respective subset of rules assigned to the first child node to the first packet.
