01
Select the operational scope
One control application, two endpoint roles, one approved flow, and one denied lateral path.
Utilities
Control-system segmentation · Evaluation
Evaluate control-system segmentation against agreed evidence.
One control application, two endpoint roles, one approved flow, and one denied lateral path.
Primary capability
Zero Trust
Evaluation plan
Test a representative scope against agreed acceptance criteria.
Restrict unauthorized lateral movement while preserving approved control-system communications.
02
Verify the technical path
Have representatives from OT security, SCADA owners, network security, grid operations review the architecture path and policy boundaries.
03
Review the decision evidence
Determine whether each operator, workload, and IACS zone can reach only its authorized control services.
Acceptance criteria
Define success with observable evidence and a decision.
Use representative systems, named owners, and a controlled operational scenario.
01
The evaluation includes one industrial automation and control system service relationship, two security zones, an approved conduit, and a denied lateral path.
02
OT, network-security, control-system, and application owners confirm the identities, service policy, and zone boundaries.
03
The team records admission decisions, allowed and denied flows, service reachability, session state, and revocation.
04
The results show whether authorized operations continue while unauthorized lateral access is denied.
Operational outcome
Restrict unauthorized lateral movement while preserving approved control-system communications.
Evaluation scope
One control application, two endpoint roles, one approved flow, and one denied lateral path.
Decision
Determine whether each operator, workload, and IACS zone can reach only its authorized control services.
