When it comes to web security, WebRTC and CORS often get thrown into the mix, but they protect against vastly different threats. Asking "is WebRTC more secure than CORS?" is like asking if a firewall is better than a seatbelt. They serve different purposes.
CORS (Cross-Origin Resource Sharing) is a browser-level security mechanism that prevents JavaScript code running on one origin (domain, protocol, and port) from making requests to a different origin. It's about preventing malicious websites from accessing your data on *other* sites without permission.
WebRTC (Web Real-Time Communication), on the other hand, enables direct peer-to-peer communication in the browser, often for video and audio. WebRTC's security focuses on encrypting the data stream between peers and authenticating those peers. It's about securing the *communication itself*.
So, WebRTC isn't inherently "more secure" than CORS. They address different vulnerabilities. You need CORS to protect against cross-site data theft, and you need robust WebRTC security to protect the privacy of your real-time communication. They work together to create a more secure web experience.
