Procedure AC-07 — Grant vendor remote access
- Confirm a signed work order exists and names the vendor engineer. No name, no access.
- Open a time-boxed account on the brokered jump host, scoped to the target zone only. Default expiry: end of the booked window.
- Enable the conduit rule for the session (firewall object
vendor-rdp-temporary). It is disabled by default; do not make it permanent. - Notify the service owner, or the on-shift operator on a plant, that a vendor session is live and on which asset.
- Watch the session, or record it, per the work order.
- At the end of the window: disable the conduit rule, expire the account, and note the session in the site file.
