Are WebSockets relevant?
I think that accepted answer is correct, websockets are still preferred solution for web applications to communicate with server bi-directionally including server-pushed messages. HTTP is used for more than just browsers and when both client and server can use low-level API, they don’t need websockets.
Does WebSocket use HTTP?
WebSocket uses HTTP as the initial transport mechanism, but keeps the TCP connection alive after the HTTP response is received so that it can be used for sending messages between client and server. WebSockets allow us to build “real-time” applications without the use of long-polling.
How are WebSockets used in the TCP / IP model?
Because of this shortcoming of HTTP, a new protocol known as WebSocket, which runs over the same TCP/IP model, was designed. WebSockets provide a persistent connection between client and server that both parties can use to start data at any time. The connection is initiated from client through a WebSocket handshake.
Can a WebSocket connection be established outside the browser?
WebSocket connections can easily be established outside a browser. You will deal with arbitrary data no matter what. This data needs validation as well as any other that comes from a client before it gets processed. Why? Because injection attacks like OS, SQL, Blind SQL are possible via WebSockets.
Are there any vulnerabilities in the WebSocket protocol?
In conclusion, WebSockets aren’t your standard socket implementation. WebSockets are versatile, the established connection is always open, and messages can be sent and received continuously. However, DOS attacks, no authentication/authorization, vulnerability to data input attacks are all vulnerabilities that are exploitable.
Is it dangerous to use raw sockets in TCP?
Everyone always says that using raw sockets is dangerous as all packets sent are susceptible to packet sniffing. So why didn’t the original implementation of TCP sockets include a basic form of encrypion.
