In the context of Illumio, what is a major focus of policy management?

A major focus of policy management in Illumio is traffic regulation and control. This involves defining and enforcing policies that determine how applications, workloads, and services communicate with one another within a secure environment. By effectively regulating traffic, organizations can minimize the attack surface and prevent unauthorized access, thereby enhancing security.

Illumio's policy management allows for granular control over network traffic, enabling administrators to specify which workloads can communicate, under what circumstances, and to what extent. This not only helps in maintaining compliance with security standards but also facilitates the containment of threats, as traffic can be restricted based on the principle of least privilege.

In contrast, other areas like centralized data collection, user permission enforcement, and cost management for services, while important in their own rights, do not specifically address the core function of policy management in Illumio, which is primarily centered around managing and controlling network traffic flows to enhance security posture.
