Abstract
An analog signal can be received. The analog signal can preserve native RF characteristics of a device RF signal received from a wireless device operating in a closed environment. An analog signature of the wireless device can be generated based on the native RF characteristics of the device RF signal. A digital signature of the wireless device can be generated based on information of network packets received from the wireless device. The analog signature and the digital signature can be correlated with characteristics of each known device of a plurality of known devices. The wireless device can be determined to be an unauthorized device based on correlating the analog signature and the digital signature with the characteristics of each known device.
