What is the best mitigation technique for keeping data and applications of different sensitivity secure in a virtualization environment?

Segmentation is the best mitigation technique for keeping data and applications of different sensitivity secure in a virtualization environment because it involves dividing the virtualized environment into distinct segments or sections. This separation ensures that sensitive data and applications are isolated from less sensitive ones, which limits the risk of unauthorized access and potential data leaks.

In a virtualized environment, multiple virtual machines (VMs) often operate on the same physical hardware. By applying segmentation, each VM can have its own set of security policies, resources, and access controls tailored to the specific sensitivity of the data it handles. This means that even if one segment is compromised, the breach is contained, preventing it from affecting more sensitive segments.

Moreover, segmentation can be implemented through various means, such as creating virtual LANs (VLANs) or using firewalls to enforce rules between segments, further enhancing security. Segmentation also helps in compliance with regulatory requirements, as it allows organizations to demonstrate that they are taking appropriate measures to safeguard sensitive information.

In contrast, while encryption, redundancy, and access controls are also important security measures, they serve different purposes or operate on different principles. Encryption protects data at rest or in transit by making it unreadable without the appropriate keys, but it does not inherently isolate different
