Guidance for reviewing vendor access, remote engineering support, jump hosts, account ownership and session evidence in OT environments.

Map access before changing controls
Remote access paths can accumulate over years through vendor support arrangements, temporary project connections and site-specific workarounds. Blocking access without understanding support requirements can create operational risk.
A review should first identify who connects, through which path, for what purpose, with what approval and what evidence is retained.
Review evidence and ownership
Useful evidence includes account ownership, approval records, session logging, jump host configuration, supplier responsibilities and disablement processes.
The target is controlled supportability: reducing unnecessary exposure while preserving maintainable routes for genuine operational support.
