You can configure a Horizon Connection Server instance so that users are required to use RSA SecurID authentication or RADIUS (Remote Authentication Dial-In User Service) authentication.
RADIUS support offers a wide range of alternative two-factor token-based authentication options.
Horizon 7 also provides an open standard extension interface to allow third-party solution providers to integrate advanced authentication extensions into Horizon 7.
Because two-factor authentication solutions such as RSA SecurID and RADIUS work with authentication managers, installed on separate servers, you must have those servers configured and accessible to the Connection Server host. For example, if you use RSA SecurID, the authentication manager would be RSA Authentication Manager. If you have RADIUS, the authentication manager would be a RADIUS server.
To use two-factor authentication, each user must have a token, such as an RSA SecurID token, that is registered with its authentication manager. A two-factor authentication token is a piece of hardware or software that generates an authentication code at fixed intervals. Often authentication requires knowledge of both a PIN and an authentication code.
If you have multiple Connection Server instances, you can configure two-factor authentication on some instances and a different user authentication method on others. For example, you can configure two-factor authentication only for users who access remote desktops and applications from outside the corporate network, over the Internet.
Horizon 7 is certified through the RSA SecurID Ready program and supports the full range of SecurID capabilities, including New PIN Mode, Next Token Code Mode, RSA Authentication Manager, and load balancing.
