True or False: The level of risk is directly proportional to threat, vulnerability, and impact.

True or False: The level of risk is directly proportional to threat, vulnerability, and impact.

• A. True
• B. False
• C. Not sure
• D. Depends

Answer: (B)

Risk is defined as a function of threat, vulnerability, and impact, typically expressed as a product: risk = threat × vulnerability × impact. This means the level of risk changes with each factor, and the overall risk is shaped by multiplying all three together. It’s not a simple linear (one-to-one) proportionality to all three at once. For example, doubling the threat while keeping vulnerability and impact the same will double risk; doubling both threat and vulnerability increases risk by four times; if any factor is zero, risk drops to zero. So, while risk depends on all three, the relation is multiplicative rather than a straightforward direct proportionality to each factor simultaneously. Hence the statement is false.
