AUTHENTICATING TO A HYBRID CLOUD USING INTRANET CONNECTIVITY AS SILENT AUTHENTICATION FACTOR

Abstract:

A technique for performing authentication to a hybrid-cloud service includes selectively applying varying authentication requirements based on whether a client device can be confirmed to be connected to a private intranet. The technique includes operating a set of local agents on one or more computing machines on the intranet. When a client device requests access to the hybrid-cloud service, the client device attempts to contact one or more of the local agents. If the client device succeeds in contacting a local agent, then the client device is confirmed to be connected to the private intranet and receives relatively trusting treatment during authentication. However, if the client device fails to contact at least one local agent, the client device is not confirmed to be connected to the private intranet and receives relatively less trusting treatment.
