Secure Remote Access Review for Industrial Sites
A representative review of accumulated vendor and engineering remote-access routes across operational sites.
Client profile
Distributed industrial operator
Client situation
An industrial operator had accumulated several mechanisms for remote engineering and vendor support across its operational sites. Different technologies had been introduced at different times to meet genuine support requirements, but the organisation no longer had a single authoritative view of who could connect, how identities were controlled, where sessions were logged or how access was revoked when no longer required. The objective was not to remove remote access; operational teams depended on several of these routes. The requirement was to understand the existing exposure and establish a controlled remote-access model without compromising necessary support capability.
The engagement
What the client needed
- identify every remote-access route from external user to OT asset
- confirm account ownership, approval and revocation responsibilities
- review network restriction, privilege, logging and session evidence
- identify shared credentials, broad reach and always-on dependencies
- retain necessary engineering support while reducing unnecessary exposure
How Meridian would approach it
- trace each support path from the external user through authentication and network boundaries to the final OT asset
- review approval, identity, account ownership, MFA where appropriate, privilege and network restrictions
- assess logging, session records, connection duration and account-disablement arrangements
- identify routes with shared credentials, excessive reach or unclear operational dependency
- define practical access, monitoring and close-out actions with responsible owners
What the client would receive
- authoritative remote-access pathway register
- remote-access control review
- prioritised control-improvement plan
- residual-risk and dependency summary
- operational guidance and ownership actions
What this would enable
Client outcome
The client would receive a single view of authorised remote-access pathways, ownership and reach, together with a prioritised improvement plan that retained necessary engineering support while reducing unnecessary exposure.
Representative engagement: this scenario is based on common industrial requirements and shows how Meridian would approach the work. It is not presented as a completed client engagement.
