  • Role-based access to shared resources
    Patent number: 10277713
    Abstract: Information identifying a user as having accessed a first network device from an external network connected device is received at an intermediate network connected device from an edge network device. The intermediate network connected device is arranged between the first network device and a second network device. The intermediate network connected device, the first network device and the second network device are within the network and the external network connected device is outside the network. A request to access the second network device is received at the intermediate network connected device from the first network device. It is determined that the user is a source of the request via the first network device based upon the received information. The request from the first network device is evaluated based upon determining the user is the source of the request.
