01 / DECISION

Choose a device control that matches the task

Device authorization should protect a retained archive while the editable USB policy remains governed in its approved endpoint management service. Define where plaintext working copies exist, how a release is exported, when it enters the device restriction policy and how temporary files are removed after verification.

Shared-workstation scenario

An administrator pilots rules on a small group of shared PCs using non-sensitive test drives. Required keyboards, badge readers and approved storage stay documented before broader rollout.

02 / PROCEDURE

Run the control sequence

  1. 01

    Keep the authoritative working USB policy in the approved approved administration console.

  2. 02

    Export one named policy version to a controlled staging folder.

  3. 03

    Verify the export, then import it using the tested archive procedure.

  4. 04

    Lock and reopen the archive; compare the manifest and file counts.

  5. 05

    Remove or retain plaintext staging according to the recorded policy.

03 / RECORD

Preserve decision evidence

Record policy version, source system, export time, staging path, archive ID, import result, reopen test, manifest comparison, plaintext disposition and operator.

Stop when

  • The device restriction policy is mistaken for the live endpoint management service.
  • An import is assumed successful without reopening it.
  • Untracked plaintext exports remain on local or synced storage.

The record should show the approved policy version, tested environment, responsible people and known limitations without storing passwords or unnecessary USB policy content.

04 / BOUNDARY

Separate the surrounding controls

USB Block authorizes/restricts local devices; it does not encrypt drive contents. Device authorization does not encrypt drive contents, validate every file, govern cloud access or replace layered endpoint controls.

05 / QUESTIONS

USB-device policy questions

Should USB Block replace endpoint management?

No. Use it only for the tested local-device control role and keep central inventory, identity, monitoring and incident response in their appropriate systems.

Does blocking a USB drive encrypt its contents?

No. Authorization and encryption are separate controls; use appropriate encryption when data at rest requires protection.
