Is CSRF and CORS same?

Is CSRF and CORS same?

Cross-Site Request Forgery (CSRF) allows an attacker to make unauthorized requests on behalf of a user. We previously discussed using CORS to secure user data, while allowing some cross-origin access. CORS handles this vulnerability well, and disallows the retrieval and inspection of data from another Origin.

What is the best practice to protect against CSRF?

In short, the following principles should be followed to defend against CSRF:

  • Check if your framework has built-in CSRF protection and use it.
  • For stateful software use the synchronizer token pattern.
  • For stateless software use double submit cookies.

How do you make CORS?

For IIS6

  1. Open Internet Information Service (IIS) Manager.
  2. Right click the site you want to enable CORS for and go to Properties.
  3. Change to the HTTP Headers tab.
  4. In the Custom HTTP headers section, click Add.
  5. Enter Access-Control-Allow-Origin as the header name.
  6. Enter * as the header value.
  7. Click Ok twice.

Can you fake referer header?

Yes, the HTTP referer header can be spoofed. A common way to play with HTTP headers is to use a tool like cURL: Sending headers using cURL: How to send a header using a HTTP request through a curl call?

What’s the difference between Cors and CSRF tokens?

Unlike CSRF token, which comes with a certain complexity, CORS is just an HTTP header, enabled by default.

What is cross-site request forgery ( CSRF )?

This is called Cross-Site Request Forgery (CSRF), and since it’s not an AJAX request but works through top-level navigation, CORS will not protect you from it. This is not an in-built browser feature, but a common solution for this problem. It works like this: Every on the bank has to include a CSRF token like this:

When does Cors come into play with CSRF?

The only time the SOP comes into play with “classic” CSRF is to prevent any token from being read by a different domain. Of course, now we have CORS and all sorts of cross-domain requests are possible such as PUT and DELETE, CORS does in fact protect against these by requiring a pre-flight.

Is the same origin policy helping in anyway against CSRF?

Some of the up-voted answers already here are stating that the Same Origin Policy prevents cross-site requests, and therefore prevents CSRF. This is not the case. All the SOP does is prevent the response from being read by another domain (aka origin). This is irrelevant to whether a “classic” CSRF attack is successful or not.
