How can I prevent JSON hijacking in my web application?

To prevent JSON hijacking, you can implement several strategies such as using anti-CSRF tokens, setting proper CORS headers, and ensuring that your JSON responses are not accessible via cross-origin requests.

What are anti-CSRF tokens and how do they work?

Anti-CSRF tokens are unique, secret tokens generated by the server and sent to the client. They must be included in requests that modify state, ensuring that the request is legitimate and not forged by an attacker.

Are there any specific CORS settings I should use?

Yes, you should set the Access-Control-Allow-Origin header to specify which domains are allowed to access your resources. Avoid using a wildcard (*) in production.

Can you give me an example of how to implement these measures?

Sure! For anti-CSRF, you can generate a token in your server-side code and include it in your forms. For CORS, you can configure your server to include the appropriate headers in the response.
