Isaca Cybersecurity-Audit-Certificate Exam - Topic 1 Question 7 Discussion

Actual exam question for Isaca's Cybersecurity-Audit-Certificate exam

Question #: 7
Topic #: 1

[All Cybersecurity-Audit-Certificate Questions]

he MOST significant limitation of vulnerability scanning is the fact that modern scanners only detect:

Acommon vulnerabilities.

Bunknown vulnerabilities.

Cknown vulnerabilities.

Dzero-day vulnerabilities.

Show Suggested Answer

Suggested Answer: D

The MOST cost-effective technique for implementing network security for human resources (HR) desktops and internal laptop users in an organization is using avirtual local area network (VLAN). A VLAN is a logical grouping of network devices that share the same broadcast domain regardless of their physical location or connection. A VLAN can enhance network security by isolating different types of traffic or users from each other and applying different security policies or rules based on the VLAN membership. For example, an organization can create a VLAN for HR desktops and internal laptop users that restricts their access to only HR-related systems or resources. A VLAN can also reduce network costs by saving bandwidth, improving performance, and simplifying management.

Common vulnerabilities are the main focus, though.

I think they can detect some unknowns too, right?

Wait, are you saying they can't catch zero-days?

I'm a bit confused; I thought scanners could also detect some common vulnerabilities, but maybe that's not the main limitation?

I feel like the answer is C, known vulnerabilities, since that's what scanners are designed to detect most effectively.

I think I saw a practice question that mentioned zero-day vulnerabilities being a major concern, but I'm not sure if that's what this question is asking.

I remember reading that scanners are really good at finding known vulnerabilities, but they struggle with the unknown ones.

I feel pretty confident about this one. Vulnerability scanners are great for finding the low-hanging fruit, but they can't uncover the more advanced, unknown vulnerabilities that could be lurking in the system. I'm going to select option B.

Hmm, I'm a bit confused on this one. I know vulnerability scanners have limitations, but I'm not sure if the most significant one is that they only detect known vulnerabilities. Let me think this through a bit more.

I'm pretty sure the answer is C - known vulnerabilities. Vulnerability scanners are designed to detect common, well-known vulnerabilities, but they can't find zero-day or unknown vulnerabilities.

Okay, I think I've got it. The key here is that modern scanners are limited to detecting common, well-known vulnerabilities. They can't find the really tricky, zero-day vulnerabilities that hackers might be using. So I'm going to go with option D.

Ah, I see what they're getting at. Confidential Transactions use cryptographic techniques to conceal the amounts, but they still have to prove the transaction is valid by showing the inputs and outputs match up. So the answer has to be True.

This is a tricky one. I'm not super familiar with Splunk's syslog handling, so I'll need to review the material and think through the different approaches. Reliability is key, so I'll focus on understanding which options are most likely to ensure consistent data delivery.

This question seems straightforward. I think segregating the application and database servers into different virtual networks is the way to go.

Haha, imagine a vulnerability scanner that could detect 'unknown' vulnerabilities. That would be like a mind-reading cybersecurity tool. Sign me up for that one!

I'm pretty sure the scanners can't detect zero-day vulnerabilities. That's the whole point of a zero-day - it's something no one knows about yet. Scanners are useful, but they're not psychic.

C is the correct answer. Vulnerability scanners are great, but they're only as good as the database of known vulnerabilities they have access to. Anything new or unknown will slip through the cracks.

I think the most significant limitation is that vulnerability scanners can only detect known vulnerabilities. There are always going to be unknown and zero-day vulnerabilities out there that they can't catch.
