How does Illumio implement micro-segmentation?

Illumio implements micro-segmentation by isolating workloads with granular policies. This approach allows organizations to enforce precise security controls that apply specifically to individual workloads or groups of workloads rather than relying on broad security zones. By applying policies at a granular level, Illumio enables the segmentation of communication between workloads based on their specific needs and risks, effectively minimizing the attack surface.

This granular policy framework allows for flexibility and adaptability in the deployment of security measures, as policies can be tailored to reflect the unique characteristics of different applications and services. It provides more effective control over east-west traffic within the data center or cloud environment, which is where many attacks occur. By doing so, Illumio supports a Zero Trust security model, ensuring that no workload is inherently trusted and that security measures are continuously validated.

The other options, while potentially relevant in broader contexts, do not effectively describe how Illumio specifically implements micro-segmentation. Broad security zones (the first choice) can actually introduce vulnerabilities by creating larger security demarcations, while centralized access control (the third choice) focuses on user permissions rather than workload isolation. Limiting network bandwidth (the fourth choice) does not inherently contribute to the security of workloads but rather impacts performance and traffic management.
