Secure Your Django Application

Security is the most precious part of any application or website. A sensuous developer always focuses on security. If you're developing any web-app using Django, you must follow the procedures mentioned in this tutorial to secure your web-app.

When deploying the django application for production you must set DEBUG=False in settings.py. Because when DEBUG=True, it shows full tracebacks in the browser when an error is occurred and hence it will leak lots of information about your project: excerpts of your source code, local variables, settings, libraries used, etc.

Python provides several packages to work with environment variables. In this tutorial we will use django-environ and python-decouple to fetch data value from the environment.

For example, the contents of the .env file can be:

Add the below code in your settings.py

Add the following configurations in the settings.py.

Let the domain of your website is example.com.

Add the following configurations in the settings.py.

Let the domain of your website is example.com.

Add the following configurations in the settings.py.

For security purposes, it is a good practice to disable CORS on your site. Enabling CORS is dangerous since it allows other sites to make cross-origin requests to your site.

Clickjacking attack occurs when a malicious site tricks a user into clicking on a concealed element of another site which they have loaded in a hidden frame or iframe.

DoS is a type of attack, in which the attacker sends too much traffic/request to a server and the server can’t handle this flood of traffic due to limited memory and resources, hence the server will be crashed. To prevent this attack you must restrict the users’ request. For example, you can restrict that the users can only send only 1000 requests per hour to your site.

When DEBG is False Django sends the server errors with full traceback to the ADMINS. For security reasons, the error reports sent to the Admins’ email must not contain sensitive information, because if anybody gets access of the admin’s email, the person can gain that sensitive information.

To check the securities and vulnerabilities of your site you can use the following online tools -

Thanks for following these procedures. Always secure your sites.
