Maritime & ports | Modelled case study
Assign rotatable identities to port cranes and gate systems
Can each crane, gate, scanner, and control service be authenticated without shared terminal credentials?
The modelled organisation
A recognisable problem reaches the operating agenda
This composite scenario follows the Port OT · Terminal Operations · Automation functions. It is grounded in the cited problem context but does not identify a real customer.
Operating environment
A shipping or port operator connects vessels, bridge systems, shore services, cargo platforms, cranes, gates, agents, and communications providers.
What is at stake
A trust failure can disrupt navigation, cargo release, port throughput, or the legal provenance of documents exchanged across jurisdictions.
Situation
Expansion projects and multiple equipment vendors leave shared certificates and service accounts across safety and cargo systems.
Event that forces action
Terminal automation, network segmentation, or vendor-access incident.
Concrete system boundary
Systems this case study puts in scope
The model is specific about the operational surfaces that must be discovered, changed, or independently checked.

Modelled case study walkthrough
How this organisation would use QNSI
The walkthrough connects the real-world problem to a bounded QNSI contribution and an independently reviewable result.
Recognise the operating condition
Expansion projects and multiple equipment vendors leave shared certificates and service accounts across safety and cargo systems.
Frame the decision the owners must make
Can each crane, gate, scanner, and control service be authenticated without shared terminal credentials?
Apply QNSI to the controlled boundary
Inventory machine identities, issuers, keys, algorithms, terminal zones, vendor ownership, and rotation constraints in QNSI.
Leave the team with a concrete result
A port machine-trust register exposing cloned identities, cross-zone reach, and renewal dependencies.
Prove the result in the organisation's environment
The terminal tests operational timing, safety interlocks, failover, vendor support, revocation, and manual fallback.
What useful success looks like
A decision artifact plus proof from the real environment
The model stops at a target result. It becomes an actual case study only when a customer produces and independently validates this evidence in production.

Real-world problem grounding
Primary sources behind the model
These sources establish the external requirement, failure mode, or risk context used to model this case. They do not endorse HEOSSI or prove that QNSI completed the scenario.
Customer evidence status
This is modelled, not a customer claim
The organisation is a composite and the result is a target state. This page does not prove a deployment, customer outcome, certification, legal conclusion, regulator endorsement, or completed control.
