Claim 18:
19. A system comprising:
a host device comprising a camera, a host device processor, and at least one peripheral device;
a server comprising a server processor;
the host device processor configured to execute host device instructions to perform operations comprising:
monitor first images taken of the at least one peripheral device by the camera;
determining from a first region overlaid in the first images whether non-busy components of the at least one peripheral device show changes associated with a security threat to the host device or the at least one peripheral device;
processing a security operation to disable one or more of the host device and the at least one peripheral device when the security threat is determined to be present from the changes;
periodically instructing the at least one peripheral device to move busy components from an idle state;
determining from a second region overlaid in a second region of second images provided by the camera and after the at least one peripheral device was instructed to move the busy components whether busy components moved from the idle state; and
processing the security operation to disable one or more of the host device and the at least one peripheral device when the second region of the second images are not depicting movement of the busy components from the idle state; and
raising a security alert to the server indicating that a potential replay attack is underway with respect to the camera and the at least one peripheral device when the busy components did not move in the second images from the idle state;

the server processor configured to execute server instruction to perform second operations comprising:
receiving the security alert from the host device; and
dispatching a service engineer or a technician to the host device to inspect the at least one peripheral device and the camera of the host device.
