Transforming Perimeter Cybersecurity to a Zero Trust Strategy Using Model Based System Engineering

Noblis Speakers:
Pat Meharg, Chief Architect – Model Based Systems Engineering
Neil Gensler, Cybersecurity Engineer

The challenge enterprises face today is how to transition to a Zero Trust Architecture without impeding operations or compromising security. Applying a Model Based System Engineering (MBSE) approach provides an integrated, coherent, and consistent set of engineering products serving as the central repository for requirements, design decisions, and candidate solutions creating an Authoritative Source of Truth (ASoT). The Zero Trust Reference Architecture modeling activity is based on the CISA Zero Trust Maturity Model (v 2.0 April 2023) and the DoD Zero Trust Strategy (Oct 21, 2023). The models are purposely built at a high level of abstraction to define and describe “what” a Zero Trust Architecture and framework is intended to accomplish from two different stakeholder perspective. Each model contains the pillars, capabilities, and levels of implementation from each strategy creating a reusable set of digital artifacts. From what is referred to as 150% model, variation points are used by the enterprise and/or programs to define and describe their specific Zero Trust implementation approach. Once defined, a new model is created from the 150% model specifically tailored to their unique needs. The reuse of the reference models significantly reduces development time while aligning programs and projects to a common baseline.
