Http headers in Websockets client API
The above line sets HTTP headers in a WebSocket constructor using a library, not the native WebSocket API, which doesn't support custom headers. For more standard scenarios like authentication tokens, consider using Socket.IO or WebSocket-Node.
Securing WebSocket: Get Past the loophole
WebSocket's lack of support for HTTP headers can pose challenges, especially when it comes to security. However, multiple workarounds exist to follow WebSocket's kung-fu and make your connections safe and secure...or at least less insecure:
-
Ticketing system: It's like getting a hall pass in school, a temporary token that validates the client to establish the connection.
-
Server-side logic: Basically saying "if you're named X, you can enter my house." The tokens passing as part of URL or Subprotocols should be matched with their users.
-
Subprotocols and Query Strings: Exploiting these fields for sending authentication data for the server's validation. 'Sec-WebSocket-Protocol' never felt so useful.
Authentication: Making Your Way in Without Keys
Since WebSocket has been stubborn to let custom HTTP headers pass through, we must find other ways to carry our credentials safely:
-
Bearer tokens: Send them as part of the URL, like carrying your pass on your forehead. Make sure you have limited lifespan and scope to them.
-
Subprotocols: Use
Sec-WebSocket-Protocolheader to send bearer tokens or signed JWTs; it's like infiltrating your identity in a group of conspirators. -
Cookies: Browser can automatically include these sweet (or salty, who am I to judge?) pieces during the handshake.
JWT tokens: The Golden Ticket
When using JWT tokens, you should be aware of the security protocols to make it work effectively:
-
Rotation: Switching the tokens at regular intervals can help reduce compromising risks. It's like changing your door locks regularly.
-
Secondary Tokens: Issue a less privileged, separate JWT for WebSocket connections, like giving your guests the remote control but not the Wi-Fi password.
-
Endpoint Security: Create a REST end-point to generate the tokens for WebSocket.
Play Safe: WebSocket Security Tips
The Internet, especially with WebSocket, can be wild. Thus, constant vigil on security practices is always a good step. Heroku Dev Center's guide, for instance, provides regular updates on security practices. Keep yourself updated with WebSocket API too, as you never know when they change their heart and allow HTTP headers directly.
While it's all great knowledge, actual experience is a different ball game. So, experiment with these strategies, documents, and share your results with everyone to make the world of WebSocket a safer place.
