Living tissue is material made of active biological cells or organisms, not inert matter. In practical terms, it can grow, metabolize, respond to its environment, and degrade if conditions change. That makes it fundamentally different from conventional materials such as synthetic fibers, metals, or plastics.
For cyber security and other digital control systems, living tissue matters because it turns a product into a living process. Any system that monitors, cultivates, or controls biological material must protect sensors, automation, and data from error or tampering, because bad inputs can change the organism itself. In biofabrication and laboratory settings, defenders use access control, environmental monitoring, logging, and isolation to reduce contamination and unauthorized manipulation. The key security challenge is that the asset is not just information or hardware; it is a biological system whose behavior can change over time.
