InSpec: Inspect Your Infrastructure

InSpec is open-source testing framework for infrastructure with a human- and machine-readable language for specifying compliance, security and policy requirements.

# Disallow insecure protocols by testing

describe package('telnetd') do
  it { should_not be_installed }
end

describe inetd_conf do
  its("telnet") { should eq nil }
end

InSpec makes it easy to run your tests wherever you need.

# run test locally
inspec exec test.rb

# run test on remote host on SSH
inspec exec test.rb -t ssh://user@hostname

# run test on remote windows host on WinRM
inspec exec test.rb -t winrm://Administrator@windowshost --password 'your-password'

# run test on docker container
inspec exec test.rb -t docker://container_id

Features

• Built-in Compliance: Compliance no longer occurs at the end of the release cycle
• Targeted Tests: InSpec writes tests that specifically target compliance issues
• Metadata: Includes the metadata required by security and compliance pros
• Easy Testing: Includes a command-line interface to run tests quickly

Installation

Requires Ruby ( >1.9 ).

To simply run it without installation, you must install bundler:

bundle install
bundle exec bin/inspec help

To install it as a gem locally, run:

gem build inspec.gemspec
gem install inspec-*.gem

You should now be able to run:

inspec --help

Examples

• Only accept requests on secure ports - This test ensures that a web server is only listening on well-secured ports.

describe port(80) do
  it { should_not be_listening }
end

describe port(443) do
  it { should be_listening }
  its('protocol') {should eq 'tcp'}
end

• Use approved strong ciphers - This test ensures that only enterprise-compliant ciphers are used for SSH servers.

describe sshd_config do
   its('Ciphers') { should eq('chacha20-poly1305@openssh.com,aes256-ctr,aes192-ctr,aes128-ctr') }
end

• Test your kitchen.yml file to verify that only Vagrant is configured as the driver.

describe yaml('.kitchen.yml') do
  its('driver.name') { should eq('vagrant') }
end

Command Line Usage

exec

Run tests against different targets:

# run test locally
inspec exec test.rb

# run test on remote host on SSH
inspec exec test.rb -t ssh://user@hostname

# run test on remote windows host on WinRM
inspec exec test.rb -t winrm://Administrator@windowshost --password 'your-password'

# run test on docker container
inspec exec test.rb -t docker://container_id

detect

Verify your configuration and detect

id=$( docker run -dti ubuntu:14.04 /bin/bash )
inspec detect -t docker://$id

Which will provide you with:

{"family":"ubuntu","release":"14.04","arch":null}

Custom InSpec resources

You can easily create your own resources. Here is a custom resource for an application called Gordon. It is saved as gordon_config.rb.

require 'yaml'

class GordonConfig < Inspec.resource(1)
  name 'gordon_config'

  def initialize
    @path = '/etc/gordon/config.yaml'
    @config = inspec.file(@path).content
    @params = YAML.load(@config)
  end

  def method_missing(name)
    @params[name.to_s]
  end
end

Include this file in your test.rb:

require_relative 'gordon_config'

Now you can start using your new resource:

describe gordon_config do
  its('Version') { should eq('1.0') }
end

Testing InSpec

We perform unit, resource and integration tests.

• unit tests ensure the intended behaviour of the implementation
• resource tests run against docker containers
• integration tests run against VMs via test-kitchen and kitchen-inspec

Unit tests

bundle exec rake test

Resource tests

Resource tests make sure the backend execution layer behaves as expected. These tests will take a while, as a lot of different operating systems and configurations are being tested.

You will require:

• docker

Run resource tests with

bundle exec rake test:resources config=test/test.yaml
bundle exec rake test:resources config=test/test-extra.yaml

Integration tests

These tests download various virtual machines, to ensure InSpec is working as expected across different operating systems.

You will require:

• vagrant with virtualbox
• test-kitchen

Run integration tests with

cd test/integration
bundle exec kitchen test -t .

Chef Delivery Tests
