Primary capability

Zero Trust

Operational outcome

Define the operating constraint, systems, and decision.

Restrict unauthorized lateral movement and expose only approved operational service relationships.

01

Define the operating scope

Include OT applications, IACS security zones, remote users, Service and Route Endlets in a representative operating scope.

02

Trace the protected path

validated identity and machine state → Endlet admission → least-privilege service policy → enforcement across an approved OT conduit

03

Review the decision

Determine whether named users, workloads, and IACS zones receive only the minimum approved access.

Outcome readiness

Define the systems and constraints for protected OT boundaries.

Give network, security, and operational teams one service path to review and one decision to make.

Include OT applications in the selected scope.
Include IACS security zones in the selected scope.
Include remote users in the selected scope.
Include Service and Route Endlets in the selected scope.
Include identity and policy services in the selected scope.

Inputs

OT applications, IACS security zones, remote users, Service and Route Endlets, identity and policy services

Path

validated identity and machine state → Endlet admission → least-privilege service policy → enforcement across an approved OT conduit

Evidence

identity state, policy decision, allowed and denied flows, route visibility, session logs, and revocation timing
