Ports and Terminal Boundary
Problem
Crane, gate, and yard systems share paths with office IT and vendor remotes. CISA treats this OT pattern as critical infrastructure, not as a separate IT problem.
What it solves
A one-site packet: what can reach operations, which vendor path is still open.
How
Read-only map plus vendor closeout list. Same shape as Plant Boundary. Written for terminal ops and marine review.
