The WebSocket protocol was designed for creating web applications that need bidirectional communication between clients running in browsers and servers. In most practical use cases, WebSocket servers need to authenticate clients in order to route communications appropriately and securely.

- Requests to authenticate are made to the HTTP endpoint /authenticate/token with the internal authentication token securely passed in the header of the request.

Does WebSocket use SSL?
WebSocket Uses the Same Encryption as HTTPS (TLS/SSL)
You configure TLS (also known as SSL) encryption for WebSocket wire traffic the same way you do for HTTP, using certificates. With HTTPS, the client and server first establish a secure envelope (connection) and only then begin the HTTP protocol.
How do you secure a WebSocket endpoint?
- setup User authentification (web.xml) – done.
- enforce SSL communication (web.xml) – done.
- secure the websocket connection with a token (limited lifetime)
Is WebSocket authentication secure?
The WebSocket protocol doesn’t handle authorization or authentication. Practically, this means that a WebSocket opened from a page behind auth doesn’t “automatically” receive any sort of auth; you need to take steps to also secure the WebSocket connection.

How to secure your WebSocket connections – freeCodeCamp
Websockets allow us to achieve real-time communication among … It could be a header like X-Auth-Token: Unlike HTTP, where you have to constantly request updates, with websockets, updates are sent immediately when they are available. WebSockets keeps a single, persistent connection open while eliminating latency problems that arise with HTTP request/response-based methods. 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. The wss protocol establishes a WebSocket over an encrypted TLS connection, while the ws protocol uses an unencrypted connection. At this point, the network connection remains open and can be used to send WebSocket messages in either direction.How is WebSocket different than HTTP?

What is WebSocket key?
The |Sec-WebSocket-Key| header field is used in the WebSocket opening handshake. It is sent from the client to the server to provide part of the information used by the server to prove that it received a valid WebSocket opening handshake.
What is WebSocket handshake?
WebSockets – Overview
In computer science, handshaking is a process that ensures the server is in sync with its clients. Handshaking is the basic concept of Web Socket protocol. The following diagram shows the server handshake with various clients −
What is WebSocket support?
The WebSocket API is an advanced technology that makes it possible to open a two-way interactive communication session between the user’s browser and a server. With this API, you can send messages to a server and receive event-driven responses without having to poll the server for a reply.
Is TLS and SSL the same?
Transport Layer Security (TLS) is the successor protocol to SSL. TLS is an improved version of SSL. It works in much the same way as the SSL, using encryption to protect the transfer of data and information. The two terms are often used interchangeably in the industry although SSL is still widely used.
How do I get a WSS certificate?

- Get new certificate. …
- Generate new self-signed certificate.
Does WSS use certificates?
A: Yes, the WSS root certificate is also used for CASB Gateway traffic.
What is the difference between WebSocket and socket IO?
Key Differences between WebSocket and socket.io
It provides the Connection over TCP, while Socket.io is a library to abstract the WebSocket connections. WebSocket doesn’t have fallback options, while Socket.io supports fallback. WebSocket is the technology, while Socket.io is a library for WebSockets.
How does WSS work?
WebSockets are used to provide a connection between a client and a server so that both parties can send data at any time. The client uses a process known as the WebSocket handshake, which helps establish a connection between the server and the client.
What is Cross Site WebSocket hijacking?
Also known as cross-origin WebSocket hijacking. It is a Cross-Site Request Forgery (CSRF) on a WebSocket handshake. It arises when the WebSocket handshake request relies solely on HTTP cookies for session handling and does not contain any CSRF tokens or other unpredictable values.

Why you should not use WebSocket?
Avoid using WebSockets if only a small number of messages will be sent or if the messaging is very infrequent. Unless the client must quickly receive or act upon updates, maintaining the open connection may be an unnecessary waste of resources.
How much data can a WebSocket handle?
there is not explicit limit, however it is worth nothing that for each instances (open connection) of the consumer you can only process one WS message at once.
