Abstract
Techniques for cross-domain routing using a fractionated cross-domain solution (F-CDS) are disclosed. A first intermediate node operating in a first physical device in an assured pipeline of the F-CDS receives a data item originating at a source node in a first security domain. The first intermediate node applies a first data filter to determine that the data item complies with a data security requirement of the F-CDS. The first intermediate node transmits the data item to a second intermediate node operating in a second physical device in the assured pipeline of the F-CDS. The second intermediate node applies a second data filter to redundantly determine that first data item complies with the data security requirement of the F-CDS. The second intermediate node transmits the data item to a recipient node in a second security domain via the assured pipeline.
