InSpec: Inspect Your Infrastructure
InSpec is an 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. More options listed here: https://github.com/chef/inspec/blob/master/docs/ctl_inspec.rst
# run test locally
inspec exec test.rb
# run test on remote host on SSH
inspec exec test.rb -t ssh://user@hostname -i /path/to/key
# 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
InSpec requires Ruby ( >1.9 ).
Install it via rubygems.org
gem install inspec
Install it from source
That requires bundler:
bundle install
bundle exec bin/inspec help
To install it as a gem locally, run:
gem build inspec.gemspec
gem install inspec-*.gem
On Windows, you need to install Ruby with Ruby Development Kit to build dependencies with its native extensions.
Run InSpec
You should now be able to run:
$ inspec --help
Commands:
inspec archive PATH # archive a profile to tar.gz (default) ...
inspec check PATH # verify all tests at the specified PATH
inspec compliance SUBCOMMAND ... # Chef Compliance commands
inspec detect # detect the target OS
inspec exec PATH(S) # run all test files at the specified PATH.
inspec help [COMMAND] # Describe available commands or one spe...
inspec init TEMPLATE ... # Scaffolds a new project
inspec json PATH # read all tests in PATH and generate a ...
inspec shell # open an interactive debugging shell
inspec supermarket SUBCOMMAND ... # Supermarket commands
inspec version # prints the version of this tool
Options:
[--diagnose], [--no-diagnose] # Show diagnostics (versions, configurations)
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('protocols') {should include '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
Also have a look at our examples for:
- Using InSpec with Test Kitchen & Chef
- Using InSpec with Test Kitchen & Puppet
- Using InSpec with Test Kitchen & Ansible
- Implementing an InSpec profile
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
# run with sudo
inspec exec test.rb --sudo [--sudo-password ...] [--sudo-options ...]
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}

Testing InSpec
We perform unit
, resource
and integration
tests.
unit
tests ensure the intended behaviour of the implementationresource
tests run against docker containersintegration
tests run against VMs via test-kitchen and kitchen-inspec
Unit tests
bundle exec rake test
If you like to run only one test, use
bundle exec ruby -W -Ilib:test test/unit/resources/user_test.rb
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 vagrant:
cd test/integration
bundle exec kitchen test
Run integration
tests with AWS EC2:
export AWS_ACCESS_KEY_ID=enteryouryourkey
export AWS_SECRET_ACCESS_KEY=enteryoursecreykey
export AWS_KEYPAIR_NAME=enteryoursshkeyid
export EC2_SSH_KEY_PATH=~/.ssh/id_aws.pem
cd test/integration
KITCHEN_LOCAL_YAML=.kitchen.ec2.yml bundle exec kitchen test
In addition you may need to add your ssh key to .kitchen.ec2.yml
transport:
ssh_key: /Users/chartmann/aws/aws_chartmann.pem
username: ec2-user
