Which of the following best describes 'nanosegmentation' in Illumio?

Nanosegmentation in Illumio refers to a highly granular approach to security segmentation that targets specific workloads within a data center or network environment. By isolating these workloads, organizations can implement tailored security policies that apply only to the designated segments, allowing for enhanced protection against lateral movement of threats.

This approach not only minimizes the attack surface but also facilitates more precise control over traffic between different workloads. It recognizes that threats can originate from within a trusted network, making it essential to segment resources at a much finer level than traditional methods.

In contrast, the other options describe concepts that do not align with the core principles of nanosegmentation. For instance, broad network access does not focus on the specificity required for segmentation, while improvements in overall performance typically pertain to efficiency rather than security isolation. Data repository management involves organizing and maintaining databases, which is unrelated to the targeted security aspect that nanosegmentation addresses.
