SYSTEM AND METHOD FOR CONTEXT AWARE NETWORK FILTERING
First Claim
1. A method for automatically filtering network messages in an aviation network for an aircraft based on a current system context, the method comprising:
- receiving (401), by a processor (501) of a computer system (500), a network message (415) transmitted via one or more network packets within the aviation network, wherein the network message is transmitted from a source avionic device to a destination avionic device;
establishing (403), by the processor, a current system context (419) based on monitoring one or more avionic devices in the aviation network, wherein the system context indicates an aggregate status (417) of the one or more avionic devices;
analyzing (405), by the processor, an acceptability of the network message by;
identifying (409) a plurality of attributes (425) corresponding to the network message, wherein the plurality of attributes correspond to header and data fields (427) of the one or more network packets corresponding to the network message; and
determining (411) the acceptability of the network message within the system context based on one or more filter rules (429), wherein the one or more filter rules specify what attributes are allowed within a particular system context; and
forwarding (407), by the processor, the network message to the destination avionic device if the network message is determined to be acceptable within the system context.

Abstract
In general, certain embodiments of the present disclosure provide techniques or mechanisms for automatically filtering network messages in an aviation network for an aircraft based on a current system context. According to various embodiments, a method is provided comprising receiving a network message transmitted from a source avionic device to a destination avionic device via one or more network packets within the aviation network. A current system context, indicating an aggregate status of avionic devices within the aviation network, is determined based on monitoring the avionic devices. The network message is analyzed by identifying a plurality of attributes corresponding to header and data fields of the one or more network packets corresponding to the network message. The acceptability of the network message within the current system context is determined based on one or more filter rules that specify what attributes are allowed within a particular system context.
