METHODS FOR FACILITATING FEDERATED SINGLE SIGN-ON (SSO) FOR INTERNAL WEB APPLICATIONS AND DEVICES THEREOF

Methods, non-transitory computer readable media, secure proxy apparatuses, and network security systems that authenticate a user in response to a request to access a web application received from a client. The authenticated user is validated as authorized to access the web application. Security attribute data is then obtained for the user subsequent to the validation. The access request is forwarded to an internal application server hosting the web application and an authentication request is received in response to the forwarded access request. An SSO token is subsequently generated based on the obtained security attribute data. The generated SSO token is sent to the internal application server to facilitate access to the web application by the user.
