T&A Terminals – Technical info
Simployer Capitech T&A terminals for our cloud customers.
The terminals are running Windows 10 IOT.
Communication:
The terminals are communicating over 3 different access points:
https://TARS-IoT-Prod.azure-devices.net (IOT-Hub)
https://sttarsstore.blob.core.windows.net (Blob-storage)
https://<customername>.capitech.no/Internal-API (Flow - only used for fetching live info for our customers that uses plan)
https://*.teamviewer.com (Access for Capitech support / PS)
The terminals communicates with the Azure region located in West Europe to access and use functionalities from IOT-hub and Blog-Storages.
The terminals communicates with the Azure region located in East Norway to access functionalities from our Flow cloud solution.
All kommunikasjon skjer over TLS 1.2 på port 443.
All communication takes place over TLS 1.2 on port 443.
IOT-hub:
Every terminal will get their own unique key.
This key is used for communication with the Azure IOT Hub.
We can withdraw this key with immediate effect.
Blob-storage:
Is used for transferring files (employee information, dimensions, logs, etc.) to and from the terminal.
Each file has its unique key, which is valid for 30 days.
URL and key are communicated to the terminal via IOT-Hub.
Live-data fetching:
For live-data fetching, communication goes directly to Flow's API.
It is first authenticated with a shared key for communication with Azure.
A unique key is then used per terminal for further communication.
Team Viewer:
Team Viewer does not release an IP address or connection range for its software. The link below provides some information regarding ports and how they work.
Briefly, the following ports are tried in order: TCP/UDP 5938, TCP 443, TCP 80, all towards *.teamviewer.com.
