For more detailed security information on Django, see their security documentation.


  1. Activate Apache's SSL Module

     sudo a2enmod ssl
     sudo service apache2 restart
  2. Install SSL/TLS certificate and key

    Either place your own certificate and key pair or create a self-signed pair. Keep in mind that self-signed certificates are, arguably, not a security improvement from having no transport security. It is best to use a valid, verifiable certificate that users do not have to manually accept. Place the certificate key pair in:

     sudo mkdir /etc/apache2/ssl

    Optional: If you need to create a self-signed certificate:

     sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/apache2/ssl/apache.key -out /etc/apache2/ssl/apache.crt
  3. Add the following lines to Krakens entry in /etc/apache2/sites-available/000-default.conf

    SSLEngine on

    SSLCertificateFile "/etc/apache2/ssl/apache.crt"

    SSLCertificateKeyFile "/etc/apache2/ssl/apache.key"

After restarting the apache2 service, HTTPS will be required to access Kraken.

Enable Security Headers

Uncomment lines 30-33 of the /opt/Kraken/Kraken/settings.py. These settings make the application more secure when SSL/TLS is enable. Below are the configuration changes that these settings make:

  • Enable the Secure flag on session tokens
  • Issue CSRF tokens
  • Enables HTTP Strict Transport Security

Turn Off Verbose Errors

Verbose error messages are informative during development or while debugging the app while in the field as a tester, but should be disabled if ran on a production server as a fixed asset. Change the DEBUG variable on line 23 to False in /opt/Kraken/Kraken/settings.py to disable verbose error messages.
