Define the device-control decision
A customer arrives with print-ready files on removable media. The operator needs a controlled way to accept the job while keeping unknown devices away from other production PCs.
Create a documented exception for one known device, job and time window without turning approval into permanent trust.
Run the control sequence
- 01Confirm the job, customer contact and operator responsible for intake.
- 02Record a neutral device identifier without copying unnecessary customer data.
- 03Use the designated intake workstation and approved scanning process.
- 04Limit authorization to the device, workstation and time needed.
- 05Remove the exception and reconcile copied files when intake ends.
Preserve enough evidence
Record the workstation, Windows version, device class or identifier, customer job, operator, approving manager, rule or exception, start time, expiry, test result and rollback owner. Do not copy customer document contents into the control record.
Keep device identity, approver, workstation scope, exception expiry, screening result and rollback evidence together without copying customer document contents.
Keep surrounding controls visible
Allowlisting identifies an approved device record; it does not certify the files, firmware, owner or future behavior.
Customer USB intake can create file copies on the intake PC, spool folders, production workstations and output systems. Device authorization addresses port access only; the shop must separately scan files, restrict accounts, minimize copies, protect customer content and document deletion or retention. Verify the current Windows and USB Block release before relying on observed behavior. Assign one manager to review exceptions, blocked events and failed rollbacks. Keep the control record concise enough for front-counter staff to follow during a deadline, but specific enough for another administrator to reproduce the decision. Recheck the workstation after operating-system, driver or production-hardware changes, and never solve an urgent job by granting open-ended access.
Questions to ask
Does an approved USB device bypass malware screening?
No. Device approval and file screening are separate controls; use the approved shop screening process before opening customer files.
Does USB blocking encrypt customer drives or inspect files?
No. USB authorization controls device access on the supported PC. It does not encrypt media, validate print files or replace endpoint protection.
