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.
