Which Cisco ISE admin GUI page allows for Security Group ACLs (SGACLs) to be defined between source and destination security groups?

The correct choice pertains to the process of defining Security Group ACLs (SGACLs) within the Cisco Identity Services Engine (ISE). Specifically, the page located under Work Centers > TrustSec > TrustSec Policy > Egress Policy > Matrix provides the necessary interface to establish and manage SGACLs between defined source and destination security groups.

This part of the GUI allows administrators to visualize and configure the relationships between different security groups within an organization's network. By utilizing this matrix, admins can effectively define rules that govern the flow of traffic between varying segments, thereby ensuring that appropriate access controls are in place based on the organization's security policies. The Egress Policy is particularly significant as it determines how outbound traffic is handled, making it critical for maintaining network integrity and security.

In contrast, other options might refer to different aspects of Cisco ISE's TrustSec policy framework. For example, the option related to Components > SGACLs typically serves as a repository or list of defined SGACLs rather than a place for active policy configuration or visualization. Each part of the GUI serves a specific purpose within the broader TrustSec structure, but for the task of defining SGACLs specifically in the context of traffic between security groups, the Egress Policy matrix is the essential tool
