CRISC · Question #518

Which of the following is MOST important to consider when assessing the likelihood that a recently discovered software vulnerability will be exploited?

The correct answer is A. The skill level required of a threat actor. When assessing the likelihood of a software vulnerability being exploited, the most important factor is the skill level required by a threat actor. Lower skill requirements increase the pool of potential attackers and thus the likelihood of exploitation.

Why each option

When assessing the likelihood of a software vulnerability being exploited, the most important factor is the skill level required by a threat actor. Lower skill requirements increase the pool of potential attackers and thus the likelihood of exploitation.

AThe skill level required of a threat actorCorrect

The skill level required by a threat actor directly impacts the ease and accessibility of exploiting a vulnerability. If a vulnerability requires low skill or readily available tools, the likelihood of exploitation significantly increases because a broader range of malicious actors can exploit it.

BThe amount of personally identifiable information (PH) disclosed

The amount of PII disclosed relates to the *impact* of an exploit, not its likelihood.

CThe ability to detect and trace the threat action

The ability to detect and trace an action relates to incident response and post-exploitation, not the likelihood of the initial exploitation.

DThe amount of data that might be exposed by a threat action

The amount of data exposed relates to the *impact* of an exploit, not the likelihood of it occurring.
