Although the Executive Order on Cybersecurity, which set Zero Trust Architecture (ZTA) as the foundation of federal agency security, is only a year old there are already new developments in ZTA. The new multi-domain approach to Zero Trust is redefining the standard for how users on the network should be handled by creating a single source of truth.

ZTA assumes no implicit trust is granted to any users on the network, and it must be intrinsic throughout the entire agency’s IT environment. ZTA also requires that agencies create a central policy over their infrastructure and develop a unified security posture over everything in their network. However, the multi-domain approach with its “single source of truth” necessitates the unification of all of the legacy and independent policy control points that were traditionally spread out through different environments into a central pane of glass.

These were the key insights of a recent Government Technology Insider podcast interview with Jeff Fossett, a Principal Architect at CTG Federal, who explained the benefit of creating this central pane of glass for policies with a multi-domain approach.
