What is CSRF (Cross Site Request Forgery) and Why use in Django Form

Cross Site Request Forgery is related in that way when unauthorized commands are submitted from the user just like when the user filling form to provide information to the server. Simply it is the attack on the user when you want to communicate with the server, but you don’t know, your request is submitted to the server using your cookies and information. In this case, the server understands, this request is coming from you, but that request actually coming from a hacker which wants to get data from the server.

Cross Site Request Forgery we can also say it is a one-click attack.
There are different types of definitions of Cross Site Request Forgery as:
  • Session riding
  • Abbreviated as CSRF
  • Type of malicious exploit

It is very important to know that how this Cross Site Request Forgery is working. And we have to make our request save from such kind of malicious attack. There are different techniques we can follow to save our request.

Why use Cross Site Request Forgery (CSRF)

Actually, we want to make our request as secure as we made it to the server. When a user fills a form providing his/her details. After clicking on submit button, it creates a request to the server, which tells the server to validate the information and provide access to any application backend area.

After checking that user login details, if the details are valid, then you will get access to the application backend area related to you. It is very important to know here, if someone wants to make a request to the server using your login details, then what happened? Surely, you will get more lose.

Because, all the backend information, you will lose. It becomes possible when Cross Site Request Forgery work. In this case, the server doesn’t know, who is requesting? original user or attacker? Because the attacker is using the original user’s cookies information, on the basis of that information server understands, this request is coming from the authorized user but not.

So, you have to make attention here to make save your request. So in this  Django tutorial, we also mention, how you can use CSRF in Django form. It is very easy to use for Django developers.

CSRF Middleware in Django settings.py

We are learning Django, the Django provide protection against CSRF attack. For this purpose, Django gives us built-in Middleware, already activated when we create a new project. So, we did not need to write custom code for such protection.

The bolded middleware is used for CSRF protection, you just need to add this one if your settings.py file did not contain it.

MIDDLEWARE = [
    ‘django.middleware.security.SecurityMiddleware’,
    ‘django.contrib.sessions.middleware.SessionMiddleware’,
    ‘django.middleware.common.CommonMiddleware’,
    ‘django.middleware.csrf.CsrfViewMiddleware’,
    ‘django.contrib.auth.middleware.AuthenticationMiddleware’,
    ‘django.contrib.messages.middleware.MessageMiddleware’,
    ‘django.middleware.clickjacking.XFrameOptionsMiddleware’,
]

CSRF Token in the form to protect request to server

In this section, you will learn how you can use CSRF in Django Form to making secure requests. But you have to do one thing while creating form. You have to add one line to your form. When any user creates his/her account, registration, etc. It will be a secure request if you use one line of code for CSRF protection.

<form action=”” method=”post”>

{% csrf_token %}

….

</form>
