Providing origin insight for web applications via SessionTtraversal Utilities for Network Address Translation (STUN) messages

Providing origin insight via Session Traversal Utilities for Network Address Translation (STUN) messages for web applications, and related methods, systems, and computer-readable media are disclosed herein. In one embodiment, a method for providing origin insight for web applications via STUN messages comprises determining an origin identifier for a web application attempting to send a STUN message to a STUN server; generating the STUN message incorporating the origin identifier for the web application; and transmitting the STUN message to the STUN server. In another embodiment, a method for providing STUN services to web applications comprises receiving a STUN message from a web client, and extracting an origin identifier for a web application. Provision of a STUN service to the web application is determined based on the origin identifier. If the STUN service should not be provided, the STUN message is rejected or disregarded; otherwise the STUN message is processed.
