Abstract
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. Show more
