- Analog Control Engineering Roles
Secure remote support architecture
An OEM was connecting to installed machines through ad-hoc, inconsistent paths, with gaps in logging and unclear vendor boundaries. We prepared a repeatable access model that defines service, vendor and engineering access with zones and logging rules.
- OEM support
- Remote access
- OT network
- NDA-based
Starting point
An OEM needed a repeatable secure remote access model for installed machines across multiple countries and service partners.
Problem
Ad-hoc remote access paths created inconsistent logging, unclear vendor boundaries and operational risk for installed-base support.
Work performed
We defined access zones, controlled vendor sessions, engineering access flows and the documentation the OEM's service team needed. Implementation is project-specific; diagrams on this site are reference only.
What was delivered
Zone-oriented access concept
Vendor and service access flow definition
Session logging and review procedure outline
Emergency access rules within agreed windows
Reference architecture documentation for OEM service teams
Outcome
The OEM's service teams now have a written access model they can use across the machines' life cycle; implementation stays project-specific, following the end user's security requirements.
