A collection of tools to help secure a Django project.

Latest Version: 0.2.0b

# Django-Security

This package offers a number of models, views, middlewares and forms to facilitate security hardening of Django applications.

# Full documentation

Automatically generated documentation of `django-security` is available on Read The Docs:

* [Django-security documentation]http://django-security.readthedocs.org/en/latest/

# Installation

Install from Python packages repository:

pip install django-security

If you prefer the latest development version, install from
[django-security]https://github.com/sdelements/django-security repository on GitHub:

git clone https://github.com/sdelements/django-security.git
cd django-security
sudo python setup.py install

Adding to Django application's `settings.py` file:

INSTALLED_APPS = (
...
'security',
...
)

Middleware modules can be added to `MIDDLEWARE_CLASSES` list in settings file:

MIDDLEWARE_CLASSES = (
...
'security.middleware.DoNotTrackMiddleware',
'security.middleware.ContentNoSniff',
'security.middleware.XssProtectMiddleware',
'security.middleware.XFrameOptionsMiddleware',
)

Unlike the modules listed above, some other modules **require** configuration settings,
fully described in [django-security documentation]http://django-security.readthedocs.org/en/latest/)
Brief description is provided below.

## Middleware

Provided middleware modules will modify web application's output and input and in most cases requires no
or minimum configuration.
















Middleware
Description
Configuration
ContentNoSniff
Disable possibly insecure autodetection of MIME types in browsers. Recommended.
None.

ContentSecurityPolicyMiddleware
Send Content Security Policy (CSP) header in HTTP response. Recommended, requires careful tuning.
Required.

DoNotTrackMiddleware
Read user browser's DoNotTrack preference and pass it to application. Recommended, requires implementation in views and templates.
None.

LoginRequiredMiddleware
Requires a user to be authenticated to view any page on the site that hasn’t been white listed.
Required.

MandatoryPasswordChangeMiddleware
Redirects any request from an authenticated user to the password change form if that user’s password has expired.
Required.

NoConfidentialCachingMiddleware
Adds No-Cache and No-Store headers to confidential pages.
Required.

P3PPolicyMiddleware
Adds the HTTP header attribute specifying compact P3P policy.
Required.

SessionExpiryPolicyMiddleware
Expire sessions on browser close, and on expiry times stored in the cookie itself.
Required.

StrictTransportSecurityMiddleware
Enforce SSL/TLS connection and disable plaintext fall-back. Recommended for SSL/TLS sites.
Optional.

XFrameOptionsMiddleware
Disable framing of the website, mitigating Clickjacking attacks. Recommended.
Optional.

XssProtectMiddleware
Enforce browser's Cross Site Scripting protection. Recommended.
None.



## Views

`csp_report`

View that allows reception of Content Security Policy violation reports sent by browsers in response
to CSP header set by ``ContentSecurityPolicyMiddleware`. This should be used only if long term, continuous CSP report
analysis is required. For one time CSP setup [CspBuilder]http://cspbuilder.info/ is much simpler.

This view can be configured to either log received reports or store them in database.
See [documentation]http://django-security.readthedocs.org/en/latest/#security.views.csp_report for details.

`require_ajax`

A view decorator which ensures that the request being proccessed by view is an AJAX request. Example usage:

@require_ajax
def myview(request):
...

## Models

`CspReport`

Content Security Policy violation report object. Only makes sense if `ContentSecurityPolicyMiddleware` and `csp_report` view are used.
With this model, the reports can be then analysed in Django admin site.

`PasswordExpiry`

Associate a password expiry date with a user.

## Logging

All `django-security` modules send important log messages to `security` facility. The application should configure a handler to receive them:

LOGGING = {
...
'loggers': {
'security': {
'handlers': ['console',],
'level': 'INFO',
'propagate': False,
'formatter': 'verbose',
},
...
