django-safety 0.1.0

Sessions

• User can see all active sessions

• User can disable a given active session

• User can disable all active sessions

Force password change

• Administrators can require a password change for any user

Sessions

1. User logs in

2. We connect the logic to the user_logged_in signal

3. We create a new safety.models.Session instance

4. User can see the list of her sessions (with IP, last activity and device information)

5. User can delete a given session in the list

6. We delete both the related safety.models.Session instance and related session in store

7. User can delete all active sessions excepted the current one

8. We proceed the same way: deleting instances and related sessions from store

9. User logs out

10. We connect the logic to the user_logged_out signal

11. We delete the related safety.models.Session instance

Force password change

1. Administrator creates a PasswordChange instance and sets required to True

2. When user logs in, it will be redirected to password change form

3. Until the user does not change its password, it is not authorized to go elsewhere

4. User changes its password

5. It is now authorized to go elsewhere

Installing prerequisites

GeoIP library must be installed on your server.

On OS X with Homebrew:

brew install geoip

You also need the GeoIP databases.

For Django >= 1.9, download City and Country databases as binary (not CSV):

http://dev.maxmind.com/geoip/geoip2/geolite2/

For Django 1.8, download City and Country legacy databases as binary (not CSV):

http://dev.maxmind.com/geoip/legacy/geolite/

Create a directory wherever you want and uncompress these archives this directory. Once done, set GEOIP_PATH setting pointing to this directory:

GEOIP_PATH = '/absolute/path/to/maxmind/db/directory'

Installing django-safety

Install

$ pip install django-safety

In your settings.py, add safety to INSTALLED_APPS:

INSTALLED_APPS = (
    # Your other apps here.
    'safety',
)

In your urls.py, include safety.urls under safety namespace.

urlpatterns = [
    # Your other URLs here.
    url(r'^security/', include('safety.urls', namespace='safety')),
]

Synchronize the database:

$ python manage.py migrate safety

Great. The session feature is ready.

If you want to enable the “force password change” feature, read the next.

Enabling “force password change” feature

To enable this feature, you have two choices:

• You want to protect only specific views? Use password_change_required() decorator

• You want to protect your whole application? Use PasswordChangeMiddleware middleware

The decorator works as any Django view decorator.

#
# In your urls.py
#

from safety.decorators import password_change_required
from .views import protect_me

urlpatterns = [
    # Other URLs here.
    url(r'^protect-me/$', password_change_required(protect_me)),
]

#
# Or in your views.py (it's up to you)
#
from django.shortcuts import render
from safety.decorators import password_change_required

@password_change_required
def protect_me(request):
    return render(request, 'protect_me.html')

The middleware works as any Django middleware.

Add safety.middleware.PasswordChangeMiddleware middleware in your settings.py:

MIDDLEWARE_CLASSES = [
    'django.middleware.security.SecurityMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.auth.middleware.SessionAuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
    'safety.middleware.PasswordChangeMiddleware',
]

Done.
