Exam SY0-701 topic 1 question 194 discussion

The security team should ensure that all of the following are in place, but the most comprehensive answer that addresses cloud-based services is: A. Virtualization and isolation of resources In a cloud-based environment, virtualization and isolation of resources are critical to maintaining security best practices. Virtualization allows multiple workloads to run on the same physical infrastructure while keeping them isolated from each other, which is a foundational practice in cloud environments to prevent data leakage or unauthorized access between different tenants or applications.

Since it is in the Cloud and theoretically can be compromised at some point, in my opinion, the first thing that needs to be ensured is the confidentiality of the data. Therefore, the data should always be encrypted.

The best answer is C. Data encryption. Here's why: Virtualization and isolation of resources: While important for resource management and security, it doesn't directly address the protection of data in transit or at rest. Network segmentation: This helps in limiting the spread of potential breaches but doesn't directly protect the data itself. Data encryption: This is crucial for protecting data both in transit and at rest, ensuring that even if data is intercepted or accessed without authorization, it remains unreadable. Strong authentication policies: These are essential for controlling access to the cloud environment but don't directly protect the data once it is accessed. this makes sense to me data encryption is the basic level of security best practices.

Virtualization and isolation of resources: This ensures that each application or tenant within the cloud environment is running in its own isolated virtual environment, preventing unauthorized access or interference from other users. Network segmentation: While network segmentation is a valuable security measure, it's not as directly related to the security of the on-premises software application itself. It's more about protecting the overall network infrastructure. Data encryption: Data encryption is crucial for protecting sensitive data both at rest and in transit, but it's not the primary concern for ensuring a secure cloud-based environment. Strong authentication policies: Strong authentication policies are essential for controlling access to the cloud environment, but they don't address the isolation and protection of resources within that environment.

Network segmentation would provide a barrier between the hosting software and internal company resources

Setting up a private cloud means your data will be traveling over the internet, encryption seems like a best practice to me when compared to virtualization and isolation which could already be in place for the on-premise architecture

I'm not overly smart about this type of thing, but I *feel* like this is one of those trick questions. In order to get any sort of cloud services up you'll need virtualization. The isolation of resources may be part of the security aspect but I am not entirely sure. D is probably a stronger answer but I don't necessarily disagree with A.

D. Strong authentication policies. Ensuring a strong user authentication is crucial to prevent unauthorized access to the cloud environment. This forms the first line of defense in securing the system.
