Were you wondering how to disable the USB port on your Synology NAS through DSM? Deactivation via the DSM “operating system” is a solution that will not allow any Local users to mount any USB key.

Follow the short steps listed below to turn off the USB port:

Go to Control Panel / External Devices / Settings. Follow the instructions in the image below.

Note: By following the guide above Local Users will not have access to the USB port. If, in the future, you need to use the USB port again, remember to change the Default Permissions back.
