For an organization that is experiencing outages due to malicious code, which of the following is the BEST index of the effectiveness of countermeasures?
The correct answer is (C.) Amount of infection-related downtime as countermeasures are meant to reduce the downtime related to infection-related incidents. It's in the answer "infection-related" and the keywords "malicious code" and "outage".
Rationale:
(A.) Number of virus infections detected does not measure outages so this can't be the correct answer.
(B.) Average recovery time per incident is incorrect it is not as specific as C. It also measures time and not a number of occurrences like C and every incident is different. Some take more time some take less, so this variable measurement is not good for consistent measurement.
(D.) Number of downtime-related help desk calls is incorrect cause this could be for a number of reasons.
I said B but further analysis would be C if you being petty. (B) Average recovery time per incident speaks more of incident response than control effectiveness. (C) directly relates to the malware code infection control.
B. Average recovery time per incident
This metric measures how quickly the organization can recover from incidents caused by malicious code. A shorter average recovery time indicates that the countermeasures in place are effective at minimizing downtime and mitigating the impact of malicious code outbreaks. It directly assesses the organization's ability to respond to and recover from such incidents, which is a critical aspect of cybersecurity incident management.

The correct answer is C. Amount of infection-related downtime.
Explanation: Among the options provided, the amount of infection-related downtime is the best index of the effectiveness of countermeasures for an organization experiencing outages due to malicious code.
Here's why the amount of infection-related downtime is the best choice:
C. Amount of infection-related downtime: This metric directly measures the impact of malicious code by evaluating the total time the organization experiences downtime due to infections. Lowering downtime directly indicates the effectiveness of countermeasures.
Agreed: When an organization suffers from outages caused by malicious code, the goal of countermeasures is to reduce the impact of the malware and the amount of downtime caused by the infection. As a result, the amount of infection-related downtime is the best indicator of countermeasure effectiveness. This metric can be used to track the progress of countermeasures over time and identify areas that require further improvement.
b. average time per incident should reduce over time
