Which of the following conclusions could the CISO draw from the analysis?

A Chief Information Security Officer (CISO) is reviewing the results of a gap analysis with an outside cybersecurity consultant.

The gap analysis reviewed all procedural and technical controls and found the following:

✑ High-impact controls implemented: 6 out of 10

✑ Medium-impact controls implemented: 409 out of 472

✑ Low-impact controls implemented: 97 out of 1000

The report includes a cost-benefit analysis for each control gap.

The analysis yielded the following information:

✑ Average high-impact control implementation cost: $15,000; Probable ALE for each high-impact control gap: $95,000

✑ Average medium-impact control implementation cost: $6,250; Probable ALE for each medium-impact control gap: $11,000

Due to the technical construction and configuration of the corporate enterprise, slightly more than 50% of the medium-impact controls will take two years to fully implement .

Which of the following conclusions could the CISO draw from the analysis?
A . Too much emphasis has been placed on eliminating low-risk vulnerabilities in the past
B . The enterprise security team has focused exclusively on mitigating high-level risks
C . Because of the significant ALE for each high-risk vulnerability, efforts should be focused on those controls
D . The cybersecurity team has balanced residual risk for both high and medium controls
