Patent attributes
An access gateway may control access of user devices to remote computer resource systems in a multi-resource computing environment. The access gateway may determine an assurance level associated with a user of the multi-resource environment, where the assurance level is based on multiple authentication factors included in multiple previous access requests. The access gateway may receive, from a user device, an additional access request to access an additional resource system in the multi-resource environment. Based on a comparison of the assurance level with a threshold authentication level for the additional resource system, the access gateway may allow or deny access to the additional resource system. In addition, based on the comparison, the access system may request additional authentication data from the user device.
