Topic #: 8
[All CISA Questions]

The GREATEST concern for an IS auditor reviewing vulnerability assessments by the auditee would be if the assessments are:

Show Suggested Answer Hide Answer
Suggested Answer: A

Comprehensive and Detailed Step-by-Step Explanation:

Conducting vulnerability assessments only once per year, right before an audit, creates a false sense of security and leaves systems exposed between assessments.

Annual Testing Before Audit (Correct Answer -- A)

Risks undetected vulnerabilities for extended periods.

Example: A company only tests security before a compliance audit, allowing zero-day threats to persist for months.

Internal Team Conducting Assessments (Incorrect -- B)

Not ideal, but regular assessments are more critical.

Focusing on Critical Systems (Incorrect -- C)

Not perfect, but better than no testing at all.

Using Open-Source Tools (Incorrect -- D)

Open-source tools can be effective if properly configured.

I vaguely recall that using open-source tools isn't necessarily bad, but it might raise questions about thoroughness. So D might not be the greatest concern.

I feel like option C could be a major red flag too. If they're only assessing critical systems, what about the rest of the infrastructure?

I'm not really sure, but I remember something about internal teams possibly missing things that external experts would catch. So maybe B is a concern?

I think the biggest issue might be if the assessments are only done once a year, like option A. That doesn't seem frequent enough to catch vulnerabilities.

I think the auditor would be most worried if the assessments were done by the internal team instead of external experts. That could lead to biased or incomplete results. I'm going with option B.

Okay, I've got this. The key here is that the auditor would be most concerned if the vulnerability assessments were not comprehensive and didn't cover the entire infrastructure. That's the biggest risk, so option C is the answer.

Hmm, this is a tricky one. I'm not sure if the frequency, the source, the scope, or the tools used for the assessments would be the biggest concern. I'll have to think this through carefully.

This question seems straightforward, but I want to make sure I understand the key concern the auditor would have. I'll need to carefully read through the options to identify the one that poses the greatest risk.
