Network Security Overview
This section describes the network security features.
Port Based Authentication (802.1x)
Port based authentication enables authenticating system users on a per-port basis via a external server.
Only authenticated and approved system users can transmit and receive data. Ports are authenticated via
the RADIUS server using the Extensible Authentication Protocol (EAP). Port Authentication includes:
•
Authenticators — Specifies the port that is authenticated before permitting system access.
•
Supplicants — Specifies host connected to the authenticated port requesting to access the system
services.
•
Authentication Server — Specifies the external server, for example, the RADIUS server that
performs the authentication on behalf of the authenticator, and indicates whether the user is
authorized to access system services.
Port based authentication creates two access states:
•
Controlled Access — Permits communication between the user and the system, if the user is
authorized.
•
Uncontrolled Access — Permits uncontrolled communication regardless of the port state.
The device currently supports Port Based Authentication via RADIUS servers.
Advanced Port Based Authentication
Advanced Port Based Authentication enables multiple hosts to be attached to a single port. Advanced
Port Based Authentication requires only one host to be authorized for all hosts to have system access. If
the port is unauthorized all attached hosts are denied access to the network.
