Django Admin Restrict

Restrict admin pages using simple IP address rules.

Overview

django-adminrestrict secures access to the Django admin pages. It works by blocking requests for the admin page path unless the requests come from specific IP addresses, address ranges or domains that you specify in a model.

Requirements

django-adminrestrict requires Django 1.4 or later. The application is intended improve the security around the Django admin login pages.

Installation

Download and install django-adminrestrict using one of the following methods:

pip

You can install the latest stable package running this command:

$ pip install django-adminrestrict

Setuptools

You can install the latest stable package running:

$ easy_install django-adminrestrict

Python 3.x Only

adminrestrict requires Python 3.x and no longer supports Python 2.x.

Development

You can contribute to this project forking it from github and sending pull requests.

Configuration

First of all, you must add this project to your list of INSTALLED_APPS in settings.py

INSTALLED_APPS = (
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.sites',
    ...
    'adminrestrict',
    ...
)

Next, install the AdminPagesRestrictMiddleware middleware:

MIDDLEWARE_CLASSES = (
    'django.middleware.common.CommonMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'adminrestrict.middleware.AdminPagesRestrictMiddleware',
)

Create the appropriate tables in your database that are necessary for operation.

For django(<1.7), run python manage.py syncdb.

For django(>=1.7), run python manage.py makemigrations adminrestrict; python manage.py migrate.

IMPORTANT: When the package is configured in your project, an empty table called AllowedIP will be created in your database. If this table is empty or has one record with a "*" the package will not restrict any IPs. If you want to add specific restrictions please go to the next section.

Usage

Using django-adminrestrict is extremely simple. Once you install the application and the middleware, all you need to do is update the allowed IP addresses AllowedIP section of the admin pages.

Adding allowed IP addresses

Login to the admin pages and browse to the Adminrestrict app, and start creating recorded in the AllowedIP table. Just type in the IP addresses and save them. These will be single IPv4 addresses that are permitted to access the pages.

Managing allowed IP addresses from command line

Use the management commands to add and remove allowed IP addresses from the command line:

python manage.py addadminip 10.10.10.10

python manage.py removeadminip 10.10.10.10

Adding allowed IP addresses with wildcards

Create a AllowedIP entries ending with a "*" to any IPs that start with the specified pattern. For example, adding 192.* would allow addreses starting matching 192...* to access the admin pages.

Adding allowed IP addresses using CIDR ranges

Create a AllowedIP entries denoted in CIDR notation, to indicate a range of IP addresses that would be allowed to login/access the admin pages. For example, a CIDR range with a suffix indicating the number of bits of the prefix, such as 192.0.2.0/24 for IPv4 or 2001:0db8:85a3:0000::/64 for IPv6 would indicate an entire subnet allowed to access the admin pages.

Adding allowed IP addresses using domain names

Create AllowedIP records with domain names starting with a lower-case or upper-case character. These domain names' corresponding IP addresses will be allowed to access the admin pages. Recommended use case: dynamic DNS domain names.

Adding * to disable all restrictions

Create a single AllowedIP record with "*" as the IP address, to temporarily disable restrictions. In this way, you do not have to modify settings.py and remove the middleware if you need to disable.

Having at least one AllowedIP record with * as the IP address effectively disables all restrictions.

Advanced Settings

There are a few advanced settings that can be engaged by adding them to your project's settings.py file:

ADMINRESTRICT_BLOCK_GET=True will block all GET requests to admin urls. By default, adminrestrict only blocks the POST method to block logins only, which is usually sufficient, because GET will redirect to the login page anyway.

ADMINRESTRICT_ENABLE_CACHE=True will cause adminrestrict to cache some of the IP addresses retrieved from the AllowedIP model to reduce read query load on your database. When any update gets made to AllowedIP models, the cache is auto-refreshed.

ADMINRESTRICT_DENIED_MSG="Custom denied msg." will let you set the response body of the 403 HTTP result when a request is denied. By default, the message is "Access to admin is denied."

ADMINRESTRICT_ALLOW_PRIVATE_IP=True will allow all private IP addresses to access the admin pages, regardless of whether the request IP matches any pattern or IP address in the AllowedIP model. Note: private IP addresses are those which comply with RFC1918.

ADMINRESTRICT_PRIVATE_IP_PREFIXES will allow overriding the default list of private IP prefixes that is used to identify an IP address as a private IP address. Defaults to ('10.', '172.', '192.', '127.')
