“…Upon receiving a packet, the remote TP can verify the zone information, decrypt the packet and, if all checks succeed, forward the packet into the local network. The latency overhead introduced by each TP is less than 5 µS [13].…”

“…To that end, this paper introduces Tableau, a modern zoning model for OT networks. Tableau builds on Mondrian [13], a recently developed zoning architecture for IT networks (see Section 4), and makes it suitable for operation on OT networks by defining a new Mondrian deployment model. By doing so, Tableau enables highly flexible network management in OT settings.…”

For over two decades, hierarchical zoning models have dominated operational technology (OT) network design. However, ongoing changes to industrial network technologies and workloads, together with rising threat levels, are now challenging this design pattern. To address these issues, this paper introduces Tableau, a new zoning architecture for OT networks. Tableau increases network flexibility by flattening the zone structure and by allowing the seamless integration of plant, edge, corporate, and cloud networks. Simultaneously, Tableau facilitates modern security practices and is IEC 62443 compatible, ensuring the continued secure operation of OT infrastructure.
