Is it safe to use WebSockets?

Like HTTPS, WSS (WebSockets over SSL/TLS) is encrypted, thus protecting against man-in-the-middle attacks. A variety of attacks against WebSockets become impossible if the transport is secured. Heroku’s SSL endpoints support WSS, and we strongly recommend that you use it.

Can WebSockets be hacked?

Some WebSockets security vulnerabilities arise when an attacker makes a cross-domain WebSocket connection from a web site that the attacker controls. This is known as a cross-site WebSocket hijacking attack, and it involves exploiting a cross-site request forgery (CSRF) vulnerability on a WebSocket handshake.

Is WebSocket secure than HTTP?

wss is secure only because it means “WebSocket protocol over https”. WebSocket protocol itself is not secure. There is no Secure WebSocket protocol, but there are just “WebSocket protocol over http” and “WebSocket protocol over https”.

Can sockets be intercepted?

You can intercept and modify them in real-time but there is no Repeater, Scanner, or Intruder functionality for WebSockets. WebSocket interception is enabled by default in Burp and all you need to do is turn on the master interception.

What are the pros and cons of WebSocket over rest?

Websockets have a lot of pros over standard RESTful services. Less overhead, push communications and raw binary streams. On the other hand, if all you return from an endpoint is static (or infrequently updated) data then maintaining the connection is overkill.

What is the difference between HTTP and WebSockets?

This is an entirely different pattern than a standard HTTP connection where to get data, the client has to request it, and then a connection is broken soon. WebSockets use HTTP protocol only to initiate communication channel, then every frame is sent by their own protocol via TCP connection in the transport layer of the OSI model.

What is the best alternative to WebSockets?

SSE is an excellent alternative to WebSockets. They are limited to the browser’s connection pool limit of ~6 concurrent HTTP connections per server, but they provide a standard way of pushing data from the server to the clients over HTTP, which load balancers and proxies understand out-of-the-box.

Are there any proxies that don’t support WebSockets?

There are still several proxies and transparent proxies not supporting WebSockets. A WebSocket server requires different optimizations than traditional Web servers, so that a dedicated platform might be required. The best approach is to use WebSockets but be ready to automatically fallback to HTTP Streaming and HTTP Long Polling when needed.
