This week, part 9: Guest and web authentication
Webauthentication can be used for guest access. It can also being used for a last resort for authentication of normal users if the 802.1x supplicant is not working. Access to this portal can be done by a remediation VLAN with limited access to resources. The portal is using HTTP and HTTPS, because of limited access, the NAD (or WLC) will intercept the HTTP request and redirects it to the web portal.
There are two portals: Guest user portal is a portal the guest is using for logging in. The Sponsor portal is a portal being used by company employees for creating and managing guest accounts. The guest portal is customizable in available options for guest users.
To manage the RADIUS requests, the portal is installed on all required policy nodes. The configuration of the portal (and users) are replicated to all nodes. So, there is a central deployment.
You can configure multiple authorization sources in one rule. So, you can use one SSID for all used: internal production use, BYOD, Guest, etc. This is a nice feature of Cisco ISE.
