A company evaluates three security threats using the formula:
Risk Score = Probability × Impact (in ₦).
The data are:

| Threat | Probability | Impact (₦) |
|---|---|---|
| A | 0.20 | 500,000 |
| B | 0.05 | 2,000,000 |
| C | 0.10 | 800,000 |

(a) Compute the risk score for each threat.
(b) Only one threat can be mitigated due to budget limits. Assuming the company also considers the possible loss of life (Threat B could cause loss of life, the others would not), which threat should be prioritized for mitigation? Justify your choice using both the risk scores and the ethical factor.

Assuming the company also considers the possible loss of life (Threat B could cause loss of life, the others would not), which threat should be prioritized for mitigation? Justify your choice using both the risk scores and the ethical factor.

Accepted Answer

Threat B should be mitigated because it has the highest (tied) risk score and also poses a possible loss‑of‑life, an ethical priority.
