We try to systematize the risk assessment mechanism in two general threat management systems 1) the threat detection: intended to face current threats, 2) and the precautionary responses: intended to face hypothetical threats. These mechanisms could act via several specific subsystems, including the self-protection subsystem, the disease avoidance subsystem, one that we hypostatize and have called the security sense subsystem, and very probably others.
