Is WebSocket more secure?

You should strongly prefer the secure wss:// protocol over the insecure ws:// transport. 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.

Can WebSocket be hacked?

Cross-Site Websocket Hijacking (CSWH) Both attacks are possible when the server relies only on the session authentication data (cookies) to perform an authenticated action. In fact, the Cross-Site WebSocket Hijacking attack is possible when the WebSocket handshake is vulnerable to CSRF.

Are WebSockets bad?

WebSockets allow for a higher amount of efficiency compared to REST because they do not require the HTTP request/response overhead for each message sent and received. When a client wants ongoing updates about the state of the resource, WebSockets are generally a good fit.

Can WebSockets 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. You’ll get intercepted WebSocket messages the same way you do for HTTP.

How do I secure a web socket?

How to secure your WebSocket connections

1. #0: Enable CORS. WebSocket doesn’t come with CORS inbuilt.
2. #1: Implement rate limiting. Rate limiting is important.
3. #2: Restrict payload size.
4. #3: Create a solid communication protocol.
5. #4: Authenticate users before WS connection establishes.
6. #5: Use SSL over websockets.
7. Questions?

How can I test a WebSocket?

Identify that the application is using WebSockets. Inspect the client-side source code for the ws:// or wss:// URI scheme. Use Google Chrome’s Developer Tools to view the Network WebSocket communication. Use ZAP’s WebSocket tab….Use ZAP’s WebSocket tab.

1. Origin.
2. Authentication.
3. Authorization.
4. Input Sanitization.

Are web sockets still used?

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.

Are web sockets stateless?

WebSocket is a stateful protocol, whereas REST is based on stateless protocol, i.e. the client does not need to know about the server and the same hold true for the server. WebSocket connection can scale vertically on a single server, whereas REST, which is HTTP based, can scale horizontally.

Which applications use WebSocket?

If you’re still unsure and want some inspiration, here are a few killer use cases.

• Social feeds.
• Multiplayer games.
• Collaborative editing/coding.
• Clickstream data.
• Financial tickers.
• Sports updates.
• Multimedia chat.
• Location-based apps.

Are WebSockets vulnerabilities a security risk?

In principle, practically any web security vulnerability might arise in relation to WebSockets: User-supplied input transmitted to the server might be processed in unsafe ways, leading to vulnerabilities such as SQL injection or XML external entity injection.

What are WebSockets and why are they important?

WebSockets are used for all kinds of purposes, including performing user actions and transmitting sensitive information. Virtually any web security vulnerability that arises with regular HTTP can also arise in relation to WebSockets communications.

How do I protect against Cross-Site WebSocket Hijacking?

Protect the WebSocket handshake message against CSRF, to avoid cross-site WebSockets hijacking vulnerabilities. Treat data received via the WebSocket as untrusted in both directions. Handle data safely on both the server and client ends, to prevent input-based vulnerabilities such as SQL injection and cross-site scripting.

How to secure WebSocket connection with CSRF token?

Use session-individual random tokens (like CSRF-Tokens) on the handshake request and verify them on the server. Websockets must be configured to use secure TCP channel. URI with syntax wss:// illustrates the usage of secure Websocket connection.
