Protected OT boundaries · Evaluation
Evaluate protected OT boundaries against agreed evidence.
One OT application, two user or workload identities, and one denied lateral-access scenario.
Primary capability
Zero Trust
Evaluation plan
Test a representative scope against agreed acceptance criteria.
Restrict unauthorized lateral movement and expose only approved operational service relationships.
02
Verify the technical path
Have representatives from OT security, network security, application owners, plant operations review the architecture path and policy boundaries.
03
Review the decision evidence
Determine whether named users, workloads, and IACS zones receive only the minimum approved access.
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, process-control, network-security, and application owners confirm the identities, service policy, and zone boundaries.
03
The team records identity evidence, admission decisions, allowed and denied flows, service reachability, session state, and revocation.
04
The results show whether required operations continue while unauthorized lateral access is denied.
Operational outcome
Restrict unauthorized lateral movement and expose only approved operational service relationships.
Evaluation scope
One OT application, two user or workload identities, and one denied lateral-access scenario.
Decision
Determine whether named users, workloads, and IACS zones receive only the minimum approved access.
