Example

[0022]A detailed description of one or more embodiments of the disclosed apparatus and method are presented herein by way of exemplification and not limitation with reference to the Figures.

[0023]FIG. 1 schematically illustrates a gas turbine engine 20. The gas turbine engine 20 is disclosed herein as a two-spool turbofan that generally incorporates a fan section 22, a compressor section 24, a combustor section 26 and a turbine section 28. Alternative engines might include an augmentor section (not shown) among other systems or features. The fan section 22 drives air along a bypass flow path B in a bypass duct, while the compressor section 24 drives air along a core flow path C for compression and communication into the combustor section 26 then expansion through the turbine section 28. Although depicted as a two-spool turbofan gas turbine engine in the disclosed non-limiting embodiment, it should be understood that the concepts described herein are not limited to use with two-spool tu

Abstract

A cyber monitored control system includes a controller with a first processing resource operable to execute a control application for a controlled system. The cyber monitored control system also includes a cyber monitor with a second processing resource isolated from the first processing resource. The cyber monitor is operable to evaluate a plurality of inputs to the cyber monitored control system with respect to a cyber threat model, apply trending using the cyber threat model to distinguish between a fault and a cyber attack, and isolate one or more subsystems of the cyber monitored control system based on identifying the cyber attack.
