An apparatus is described that provides security and monitoring in a networking architecture. One embodiment of the apparatus includes a physical layer interface that includes a physical layer receiver and a decoder for converting physical layer data from the physical layer receiver to data link layer information, wherein the decoder processes input data corresponding to the physical layer data based on rules conditioned on higher layer information to generate output data corresponding to the data link layer information; and a controller for provisioning the physical layer interface. Advantageously, the apparatus provides an architectural framework well suited to a low cost, high speed, robust implementation of flexible, advanced network security and monitoring features, traffic management, and network traffic analysis.
