When calculating a risk rating, if the Impact rating is 25, the threat is .25, and vulnerability is .35, what is the overall risk rating?

To compute the overall risk rating, you multiply the Impact rating, Threat level, and Vulnerability rating together. In this case, the calculation follows this formula:

Overall Risk Rating = Impact × Threat × Vulnerability.

Given the values:

• Impact rating = 25

• Threat = 0.25

• Vulnerability = 0.35

Substituting the values into the formula gives:

Overall Risk Rating = 25 × 0.25 × 0.35.

First, calculate the Threat and Vulnerability component:

0.25 × 0.35 = 0.0875.

Then, multiply that result by the Impact rating:

25 × 0.0875 = 2.1875.

Therefore, the computed overall risk rating is 2.1875, which corresponds to the indicated answer. This demonstrates how to correctly evaluate the risk by considering all three critical components in the risk management formula, leading to a precise understanding of the overall risk level.
