Is CSRF necessary?

Server headers are generally easy for an attacker to manipulate. However, a comparison of existing server headers does not provide sufficient protection against CSRF attacks, which is why a matching CSRF token is necessary. A CSRF token should be sent with every action that can result in a change of status.

What is the difference between CSRF and XSRF?

Cross-site request forgery, also known as one-click attack or session riding and abbreviated as CSRF (sometimes pronounced sea-surf) or XSRF, is a type of malicious exploit of a website where unauthorized commands are submitted from a user that the web application trusts.

How to avoid CSRF on REST APIs?

The client can go ahead and send the access token thus acquired to api.example.comwithout CSRF, as no cookies will be sent to that host. So, you can still safely avoid dealing with CSRF on your REST APIs. But your login / authentication server better be bullet-proof (and CSRF protected).

How can I protect my API requests with CSRF token-based authentication?

This protection is provided by including a CSRF token with API requests. You can put requests on an allowed list so that they do not require protection if needed. Cisco SD-WAN release 19.2 offers token-based authentication when you use the SD-WAN REST API. This protection is provided by requiring that a token be included with API requests.

Are cookie-less REST APIs completely immune from CSRF attacks?

Since authentication is application-specific, and since the browser itself doesn’t know what the authentication token is, there is no way for a browser to automatically provide authentication credentials even if it is somehow tricked into visiting the API endpoint. As a result, a cookie-less REST endpoint is completely immune from CSRF attacks.
