The latest version of the Raise the Bar (RTB) initiative introduced by the National Cross Domain Strategy & Management Office (NCDSMO) requires that future Cross Domain Solution (CDS) systems deliver log data to a Defensive Cyber Operations (DCO) aggregation point. When multiple data sources from different security domains are reporting to the same DCO network, an approved one-way transfer (OWT) mechanism is required to protect the independent sources from potentially malicious content. For large-scale CDS deployments, this can result in a large concentration of OWT devices. Compliance with these requirements using conventional OWT devices will consume an impractical amount of rack space and power. This approach will also create an administrative nightmare for network operators who need to configure, manage, and monitor an individual OWT appliance for every logging port connection.
