RADIUS Server Attributes for Secure Firewall Threat Defense

The threat defense device supports applying user authorization attributes (also called user entitlements or permissions) to VPN connections from the external RADIUS server that are configured for authentication and/or authorization in the remote access VPN policy.

Note

Secure Firewall Threat Defense devices support attributes with vendor ID 3076.

The following user authorization attributes are sent to the threat defense device from the RADIUS server.

  • RADIUS attributes 146 and 150 are sent from threat defense devices to the RADIUS server for authentication and authorization requests.

  • All three (146, 150, and 151) attributes are sent from threat defense devices to the RADIUS server for accounting start, interim-update, and stop requests.
