The scheme assumes that some level of unauthenticated browsing is allowed prior to enforcing authentication at the proxy. Once a known and trusted set of identity providers has been accessed and the user is required to authenticate at the proxy (e.g., as a result of policy), the proxy initiates Federated Single Sign-On (F-SSO) to one or more (or, preferably, all) known sites accessed by the browser. This F-SSO operation is performed seamlessly, preferably without the user's knowledge (after the user allows an initial trust decision between the proxy acting as a service provider and the external identity provider). The proxy collates the results and, based on the trust it has with those sites, produces a confidence score. That score is then used as input into policy around whether or not a user should be permitted to access a particular site."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Confidence-based authentication discovery for an outbound proxy","description":"A confidence-based authentication discovery scheme is implemented at a proxy.
