HTTP Observatory: a set of tests and tools to scan your website for basic web hygeine.

Project description

Mozilla HTTP Observatory - Build Status Requirements Status

The Mozilla HTTP Observatory is a set of tools to analyze your website and inform you if you are utilizing the many available methods to secure it.

It is split into three projects:

Scanning sites with the HTTP Observatory

Sites can be scanned using:



  • Python 3
  • Git
  • pip3


These instructions assume that you have a working Python3 development environment with pip3 installed and capable of building requirements, which may require installing an additional python OS package (-dev, -devel).

If this is not appropriate for your environment, you may install the appropriate requirements using your OS package manager (or other means) and skip the pip3 -r requirements command.

Running a scan from the local codebase, without DB, for continuous integration

# Install the HTTP Observatory
$ git clone
$ cd http-observatory
$ pip3 install --upgrade .
$ pip3 install --upgrade -r requirements.txt

Using the local scanner function calls

>>> from httpobs.scanner.local import scan
>>> scan('')  # a scan with default options
>>> scan('',  # all the custom options
         http_port=8080,             # http server runs on port 8080
         https_port=8443,            # https server runs on port 8443
         path='/foo/bar',            # don't scan /, instead scan /foo/bar
         cookies={'foo': 'bar'},     # set the "foo" cookie to "bar"
         headers={'X-Foo': 'bar'},   # send an X-Foo: bar HTTP header
         verify=False)               # treat self-signed certs as valid for tests like HSTS/HPKP

The same, but with the local CLI

$ httpobs-local-scan --http-port 8080 --https-port 8443 --path '/foo/bar' \
    --cookies '{"foo": "bar"}' --headers '{"X-Foo": "bar"}' --no-verify

Running a local scanner with Docker

# Install the HTTP Observatory client and requests library
$ git clone
$ cd http-observatory
$ pip3 install .
$ pip3 install --upgrade requests

# Create docker machine
$ docker-machine create --driver virtualbox --virtualbox-disk-size "40000" http-observatory

# Save the URL to the API in your .profile, .bash_profile, or whatever
$ echo export HTTPOBS_API_URL=http://$(docker-machine ip http-observatory):57001/api/v1 >> ~/.profile
$ . ~/.profile

# Start up the docker instance and install all the pieces
$ eval $(docker-machine env http-observatory)
$ docker-compose up -d

Creating a local installation (tested on Ubuntu 15)

# Install git, postgresql, and redis
# sudo -s
# apt-get install -y git libpq-dev postgresql redis-server

# Clone the repo
# cd /opt
# git clone
# cd http-observatory

# Install the observatory and scanner
# pip install .
# pip3 install -r requirements.txt

# Install the database
# su - postgres
$ createdb http_observatory
$ psql http_observatory < httpobs/database/schema.sql
$ psql http_observatory
http_observatory=# \password httpobsapi
http_observatory=# \password httpobsscanner
# vi /etc/postgresql/9.4/main/postgresql.conf (set max_connections = 512, shared_buffers = 256MB)
# service postgresql restart

# Create the httpobs user, and log/pid directories
# useradd -m httpobs
# install -m 750 -o httpobs -g httpobs -d /var/run/httpobs /var/log/httpobs

# Update the environmental variables
# su - httpobs
$ echo export HTTPOBS_API_URL="http://localhost:57001/api/v1" >> ~/.profile

# Start the scanner
$ cd /opt/http-observatory

# Start the API (in another terminal)
    uwsgi --http :57001 --wsgi-file httpobs/website/ --processes 8 --callable app --master
