How can I prevent JSON hijacking in my web applications?

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 headers I should set?

Yes, you should set the Access-Control-Allow-Origin header to specify which domains are allowed to access your resources. Additionally, consider using Access-Control-Allow-Credentials to control whether cookies are sent with requests.

Can you give me an example of a secure JSON response?

Sure! A secure JSON response might include a unique token in the response body, and you should ensure that sensitive data is not exposed. For example: { "data": "some secure data", "token": "unique_token_value" }.
