The risk associated with an asset before controls are applied is also known as the inherent risk. It is the level of risk that exists in the absence of any mitigating actions or measures. To express the inherent risk, one needs to consider two factors: the likelihood and the impact of a potential threat. The likelihood is the probability or frequency of a threat occurring, while the impact is the magnitude or severity of the consequences if the threat materializes. The inherent risk can be calculated by multiplying the likelihood and the impact, or by using a risk matrix that assigns a risk rating based on the combination of these two factors. The other options are not correct ways of expressing the inherent risk, as they do not account for both the likelihood and the impact of a threat. The magnitude of an impact is only one component of the risk, and it does not reflect how likely the threat is to happen. The function of the cost and effectiveness of control is related to the residual risk, which is the risk that remains after controls are applied. The likelihood of a given threat is also only one component of the risk, and it does not indicate how severe the impact would be if the threat occurs.
