Which solution simplifies management of secure access to network resources?

Cisco TrustSec simplifies secure access management by logically segmenting the network and applying policies based on user roles and device posture, rather than IP addresses or VLANs. This role-based access control (RBAC) uses Security Group Tags (SGTs) to classify traffic, making policy enforcement more scalable and easier to manage across a dynamic network. While RFC 3580 (RADIUS EAP) and ISE both contribute to secure access, TrustSec specifically focuses on simplifying the management of these policies across the network by abstracting access decisions from network topology. 802.1AE (MACsec) secures communication at Layer 2 but doesn't inherently simplify access policy management.
