Where in the taxonomy do deterrent controls play a role in reducing Loss Event Frequency?

Deterrent controls are mechanisms put in place to dissuade individuals or entities from undertaking actions that could lead to potential risks or losses. In the context of the FAIR framework, these controls specifically impact the probability that a harmful action will be initiated by a threat actor.

The correct answer reflects that deterrent controls reduce the likelihood of a loss event averting potential negative actions. By discouraging threat actors from attempting to exploit vulnerabilities or engage in activities that could lead to a loss, their effect is directly linked to reducing the probability of an action occurring. For example, implementing security measures such as surveillance cameras or strict access controls serves to deter unauthorized actions, thereby lowering the probability of a successful breach.

In contrast, the other categories do not adequately address how deterrent controls function. Loss Magnitude refers to the potential impact of a loss once it has occurred rather than the frequency of the loss event. Vulnerability assesses the susceptibility to loss, which does not involve active deterrence. Contact Frequency pertains to how often an entity interacts with potential threats but does not encompass the action-oriented aspect that deterrent controls specifically target.
