SYSTEM AND METHOD FOR SAFELY RELAYING AND FILTERING KERBEROS AUTHENTICATION AND AUTHORIZATION REQUESTS ACROSS NETWORK BOUNDARIES

A system and method for providing secure access to an organization's internal resources by an application running on an external network. An agent accepts queries from the application which are passed to a relay with a dynamic filter. The relay establishes a secure connection with a connector through the organization's firewall and passes requests from the application to an authentication service running on the internal network to confirm that a user of the application is authorized and issue an authentication ticket which is returned to the application. The application then sends a request to access a specific internal resource based on the authentication ticket, which is passed to a ticket granting service running on the internal network, to verify that said user is authorized to access the specific internal resource, and, if so, issue a service ticket to grant access the application for that resource.
