Question #: 216
Topic #: 1

A company has decided to expose several systems to the internet. The systems are currently available internally only. A security analyst is using a subset of CVSS3.1 exploitability metrics to prioritize the vulnerabilities that would be the most exploitable when the systems are exposed to the internet. The systems and the vulnerabilities are shown below:

Which of the following systems should be prioritized for patching?

A. brown
B. grey
C. blane
D. sullivan

Selected Answer: C

For internet facing systems, the most vulnerable are those who have attach vectors which are on the network (AV/N), have low complexity (AC/L) and have high impact on CIA (A/H). Option C, blane ticks all the 3 boxes and hence is most vulnerable and needs to be prioritised for patching

Selected Answer: A

For internet-facing systems, we should prioritize vulnerabilities with lower Access Vector (AV) and lower Attack Complexity (AC) scores. Lower scores indicate easier exploitation. So, the system that should be prioritized for patching is brown (AV:L AC:L). Therefore, the correct answer is: A. brown

Brown’s attack vector is local. No one’s touching that vulnerability if they don’t have access to the network locally. Blane’s tho, has a Network attack vector. Anyone with internet can exploit it. Complexity is low and impact on availability is high.
