ABSTRACT:
Authenticating an endpoint using a STUN server includes facilitating a communication session between a first endpoint and a second endpoint over a network. A challenge request is sent to the second endpoint. The challenge request attempts to authenticate the second endpoint and includes an identification. The identification is associated with an expected response identification. A response to the challenge request is received from the second endpoint. The response has an actual response identification. The received response is verified to establish whether the second endpoint is legitimate. The second endpoint is legitimate if the actual response identification includes the expected response identification.
