The present invention is a system and method for providing security for a mobile device by analyzing data being transmitted or received by multiple types of networks. The invention can provide security for many types of network interfaces on a mobile device, including: Bluetooth, WiFi, cellular networks, USB, SMS, infrared, and near-field communication. Data is gathered at multiple points in a given processing pathway and linked by a protocol tracking component in order to analyze each protocol present in the data after an appropriate amount of processing by the mobile device. Protocol analysis components are utilized dynamically to analyze data and are re-used between multiple data pathways so as to be able to support an arbitrary number of network data pathways on a mobile device without requiring substantial overhead.
