Reveal correct answer
Correct answer: C
Explanation
Risk = Threat x Vulnerability x Consequence From this equation, there are three components of risk which are Threat, Vulnerability and Consequences of threat exploiting vulnerability. A vulnerability without a threat cannot be exploited and, therefore, is not a risk. Equally, a threat with no vulnerability to exploit is not a risk. Therefore, Alan should do nothing as there are no humans that live nearby. Hence, there are no threats that can exploit the vulnerability of broken door handle. In the absence of threats, there are no risk of Alan’s hut being robbed. Therefore, he should not implement an expensive countermeasure of buying a new door handle.Discussion
