[![Build Status Master](https://ci.appveyor.com/api/projects/status/github/chef/inspec?branch=master&svg=true&passingText=master%20-%20Ok&pendingText=master%20-%20Pending&failingText=master%20-%20Failing)](https://ci.appveyor.com/project/Chef/inspec/branch/master)

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

```ruby
# 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

```bash
# 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

When installing from source, gem dependencies may require ruby build tools to be installed.

For CentOS/RedHat/Fedora:

```bash
yum -y install ruby ruby-devel make gcc
```

For Ubuntu:

```bash
apt-get -y install ruby ruby-dev gcc make
```

To install inspec from [rubygems](https://rubygems.org/):

```bash
gem install inspec
```

### Usage via Docker

Download the image and define an alias for convenience:

```
docker pull chef/inspec
alias inspec='docker run -it --rm -v $(pwd):/share chef/inspec'
```

If you call inspec from cli, it automatically mounts the current directory into the work directory. Therefore you can easily use local tests and key files. Note: Only files in the current directory are available to the container.

```
$ ls -1
vagrant
test.rb


$ inspec exec test.rb -t ssh://root@192.168.64.2:11022 -i vagrant
..

Finished in 0.04321 seconds (files took 0.54917 seconds to load)
2 examples, 0 failures
```


### Install it from source

That requires [bundler](http://bundler.io/):

```bash
bundle install
bundle exec bin/inspec help
```

To install it as a gem locally, run:

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

On Windows, you need to install [Ruby](http://rubyinstaller.org/downloads/) with [Ruby Development Kit](https://github.com/oneclick/rubyinstaller/wiki/Development-Kit) to build dependencies with its native extensions.

### Run InSpec

You should now be able to run:

```bash
$ 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.

```ruby
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.

```ruby
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.

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

## Command Line Usage

### exec

Run tests against different targets:

```bash
# 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 ...] [--sudo_command ...]
```

### detect

Verify your configuration and detect

```bash
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 implementation
* `resource` tests run against docker containers
* `integration` tests run against VMs via test-kitchen and [kitchen-inspec](https://github.com/chef/kitchen-inspec)

### Unit tests

```bash
bundle exec rake test
```

If you like to run only one test, use

```bash
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

```bash
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:**

```bash
cd test/integration
bundle exec kitchen test
```

**Run `integration` tests with AWS EC2:**

```bash
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
```
