CompTIA CAS-005 Exam - Topic 3 Question 17 Discussion

Actual exam question for CompTIA's CAS-005 exam

Question #: 17
Topic #: 3

[Governance, Risk, and Compliance (GRC)]

A company wants to install a three-tier approach to separate the web. database, and application servers A security administrator must harden the environment which of the following is the best solution?

ADeploying a VPN to prevent remote locations from accessing server VLANs

BConfiguring a SASb solution to restrict users to server communication

CImplementing microsegmentation on the server VLANs

Dinstalling a firewall and making it the network core

Show Suggested Answer

Suggested Answer: C

The best solution to harden a three-tier environment (web, database, and application servers) is to implement microsegmentation on the server VLANs. Here's why:

Enhanced Security: Microsegmentation creates granular security zones within the data center, allowing for more precise control over east-west traffic between servers. This helps prevent lateral movement by attackers who may gain access to one part of the network.

Isolation of Tiers: By segmenting the web, database, and application servers, the organization can apply specific security policies and controls to each segment, reducing the risk of cross-tier attacks.

Compliance and Best Practices: Microsegmentation aligns with best practices for network security and helps meet compliance requirements by ensuring that sensitive data and systems are properly isolated and protected.

SASb solutions are great for user restrictions, but not the best here.

I disagree, a firewall at the core is more effective.

I feel like configuring a SASb solution could help, but I’m not clear on how it compares to the other options for hardening the servers.

I practiced a similar question where implementing a firewall was the answer, but I wonder if that's enough compared to microsegmentation in this case.

I’m not entirely sure, but I think deploying a VPN might not be the best solution for hardening the environment. It feels more like a network access control measure.

I remember studying about microsegmentation and how it can enhance security by isolating different server types. It seems like a strong option here.

I'm a bit confused by the options. Deploying a VPN or a SASL solution doesn't seem to directly address the requirement of separating the server tiers. Installing a firewall as the network core also doesn't sound like the right approach. I think I need to focus on the microsegmentation option and make sure I understand how it works to secure the three-tier architecture.

Okay, I've got this. The key is to isolate the different server tiers and control access between them. Implementing microsegmentation on the server VLANs is the way to go - it'll allow me to create granular security policies and restrict communication between the tiers. Seems like the most robust solution here.

Hmm, I'm a bit unsure about this one. The question mentions a three-tier architecture, so I'm wondering if a VPN or SASL solution might be more appropriate to control access between the tiers. I'll need to think through the pros and cons of each option carefully.

This looks like a classic network segmentation and access control question. I'd start by considering the key requirements - separating the web, database, and application servers, and hardening the environment. Implementing microsegmentation on the server VLANs seems like the best approach to achieve that.

SASb? Is that some kind of new acronym? Microsegmentation is the industry-standard approach for this use case.

SASb stands for Secure Access Service Edge, it's a cloud-native security solution.
