System and method for a WPAN firewall

Systems and methodologies for implementing Wireless Personal Area Network (WPAN) security are provided herein. As disclosed herein, firewall functionality can be implemented for a WPAN-capable device to control access to resources of the device over a WPAN. In one example, a WPAN protocol can be extended to include low-level access control measures that enable analysis of communication requests to and/or from a device prior to acting on the requests. As described herein, a WPAN firewall associated with a device can be configured to block, monitor, and/or log respective resource accesses to and/or from a WPAN. WPAN firewall functionality as described herein can be configured using mechanisms such as an Application Programming Interface (API) and/or a user control interface. Additionally, lateral regulation of security policies for a WPAN and one or more other networks utilized by a device can be provided.
