How do SameSite cookies contribute to CSRF protection?
- CSRF is entirely unrelated to SameSite cookies.
- Mitigates CSRF by restricting cookie access based on the request source.
- Prevents CSRF by encrypting cookies to make them inaccessible to attackers.
- SameSite cookies have no impact on CSRF protection.
SameSite cookies contribute to CSRF protection by restricting cookie access based on the request source. This helps prevent malicious requests from other sites that might attempt to perform actions on behalf of the user. It's an additional layer of security to ensure that cookies are only sent in a first-party context, reducing the risk of CSRF attacks.
