1. A risk assessment method comprising: receiving, by an inference engine within a computing system, first sensor cohort data associated with a first cohort, said first cohort located within a first airport; receiving, by said inference engine, first group technology inferences associated with said first cohort; generating, by said inference engine, first risk cohort inferences, said generating said first risk cohort inferences based on said first group technology inferences and said first sensor cohort data; receiving, by said inference engine, first inference data generated by said inference engine, said first inference data comprising a first plurality of inferences associated with said first cohort and a security perimeter area surrounding said first airport; receiving, by said inference engine, second inference data generated by said inference engine, said second inference data comprising a second of plurality of inferences associated with said first cohort and a pre/post security area within said first airport; receiving, by said inference engine, third inference data generated by said inference engine, said third inference data comprising a third of plurality of inferences associated with said first cohort and a gate area within said first airport; receiving, by said inference engine, fourth inference data generated by said inference engine, said fourth inference data comprising a fourth of plurality of inferences associated with said first cohort and a second airport; receiving, by said inference engine, fifth inference data generated by said inference engine, said fifth inference data comprising a fifth of plurality of inferences associated with said first cohort and an aircraft; receiving, by said inference engine, sixth inference data generated by said inference engine, said sixth inference data comprising a sixth of plurality of inferences associated with said first cohort and said first airport; generating, by said inference engine, seventh inference data, said seventh inference data comprising a seventh plurality of inferences associated with said first cohort and said first airport, wherein said generating said seventh inference data is based on said first risk cohort inferences, said first inference data, said second inference data, said third inference data, said fourth inference data, said fifth inference data, and said sixth inference data; generating, by said inference engine based on said seventh inference data, a first associated risk level score for said first cohort; and storing, by said computing system, said seventh inference data and said first associated risk level score.
