Abstract
Techniques for securely monitoring an air-gapped machine. Systems, methods, and devices for generating a status message representing a state of an air-gapped machine, converting the status message to a visual code, displaying the visual code to a display monitor connected to the air-gapped machine, capturing image data of the visual code at a camera connected to a monitoring machine, and transmitting the image data to the monitoring machine, thereby causing the visual code to be accessible by a user of the monitoring machine. Techniques for verifying the integrity of the status message, and optionally, encrypting the status message.
