1. A computing system for managing security threats, the computing system comprising: a processor to execute: a threat detection module to detect the existence of a security threat to the computing system; a threat mitigation analysis module to determine a plurality of mitigation scenarios to employ to mitigate the security threat and implement each of the plurality of mitigation scenarios on the computing device to mitigate the security threat, wherein each mitigation scenario comprises (i) one or more threat mitigation actions to be performed by the computing system, (ii) one or more threat response systems of the computing system to be used to perform the selected threat mitigation actions, and (iii) a temporal sequence of the determined mitigation actions, wherein the temporal sequence defines an order in which the determined mitigation actions are to be performed; and an evaluation module to (i) evaluate a threat mitigation result of each mitigation scenario, (ii) select one of the mitigation scenarios from the plurality of mitigation scenarios to respond to future security threats based on the evaluation of the threat mitigation results, and (iii) store the selected threat mitigation scenario as a validated threat mitigation scenario to use to respond to the security threat; and a user habituation module to implement a threat scenario on the computing system to replicate the security threat, wherein the threat mitigation analysis module is to receive the validated threat mitigation scenario and implement the validated threat mitigation scenario to mitigate the threat scenario, and wherein the user habituation module is further to request, from a user, at least one threat mitigation user interaction with the computing system and reward the user based on the at least one threat mitigation user interaction to habituate the user in responding to the security threat.
