Files being copied between the removable storage device and the host computer through the adaptor are scanned for malware using the scan engine.
Claims18
An industrial control system comprising:
- an adaptor comprising a first connector and a second connector, the first connector of the adaptor being removably connected to a connector of a host computer, the adaptor comprising a non-volatile memory that stores a scan engine;
- a removable storage device comprising a first connector that is removably connected to the second connector of the adaptor, the removable storage device storing a first file;
- and
- the host computer that is configured to control an industrial equipment, the host computer operable to receive the scan engine from the adaptor, and to execute the scan engine to scan the first file being copied from the removable storage device to the host computer through the adaptor for malware.
