title: About InSpec Profiles
---
# InSpec Profiles
InSpec supports the creation of complex test and compliance profiles, which organize controls to support dependency management and code reuse. Each profile is a standalone structure with its own distribution and execution flow.
# Profile Structure
A profile should have the following structure::
examples/profile
├── README.md
├── controls
│ ├── example.rb
│ └── control_etc.rb
├── libraries
│ └── extension.rb
|── files
│ └── extras.conf
2016-09-21 16:58:25 +00:00
└── inspec.yml
where:
* `inspec.yml` includes the profile description (required)
* `controls` is the directory in which all tests are located (required)
* `libraries` is the directory in which all InSpec resource extensions are located (optional)
* `files` is the directory with additional files that a profile can access (optional)
2016-09-21 16:58:25 +00:00
* `README.md` should be used to explain the profile, its scope, and usage
See a complete example profile in the InSpec open source repository: https://github.com/chef/inspec/tree/master/examples/profile
## inspec.yml
Each profile must have an `inspec.yml` file that defines the following information:
* Use `name` to specify a unique name for the profile. Required.
* Use `title` to specify a human-readable name for the profile.
* Use `maintainer` to specify the profile maintainer.
* Use `copyright` to specify the copyright holder.
* Use `copyright_email` to specify support contact information for the profile, typically an email address.
* Use `license` to specify the license for the profile.
* Use `summary` to specify a one line summary for the profile.
* Use `description` to specify a multiple line description of the profile.
* Use `version` to specify the profile version.
* Use `supports` to specify a list of supported platform targets.
* Use `depends` to define a list of profiles on which this profile depends.
`name` is required; all other profile settings are optional. For example:
name: ssh
title: Basic SSH
maintainer: Chef Software, Inc.
copyright: Chef Software, Inc.
copyright_email: support@chef.io
license: Proprietary, All rights reserved
summary: Verify that SSH Server and SSH Client are configured securely
version: 1.0.0
supports:
- os-family: linux
depends:
- name: profile
path: ../path/to/profile
## Verify Profiles
Use the `inspec check` command to verify the implementation of a profile:
$ inspec check examples/profile
# Platform Support
Use the `supports` setting in the `inspec.yml` file to specify one (or more) platforms for which a profile is targeting. The list of supported platforms may contain simple names, names and versions, or detailed flags, and may be combined arbitrarily. For example, to target anything running Debian Linux:
name: ssh
supports:
- os-name: debian
and to target only Ubuntu version 14.04
name: ssh
supports:
- os-name: ubuntu
release: 14.04
and to target the entire RedHat platform (including CentOS and Oracle Linux):
name: ssh
supports:
- os-family: redhat
and to target anything running on Amazon AWS:
name: ssh
supports:
- platform: aws
and to target all of these examples in a single `inspec.yml` file:
name: ssh
supports:
- os-name: debian
- os-name: ubuntu
release: 14.04
- os-family: redhat
- platform: aws
# Profile Dependencies
A profile dependency is needed when:
* using `include_controls` or `require_controls` in order to load controls defined in another profile
* using a custom InSpec resource defined in another profile
2016-09-21 16:58:25 +00:00
Use the `depends` setting in the `inspec.yml` file to specify one (or more) profiles on which this profile depends. A profile dependency may be sourced from a path, URL, a git repo, a cookbook located on Chef Supermarket or on GitHub, or a profile located on the Chef Compliance server.
## Path
The `path` setting defines a profile that is located on disk. This setting is typically used during development of profiles and when debugging profiles. This setting does not support version constraints. If the location of the profile does not exist, an error is returned.
For example:
depends:
- name: my-profile
path: /absolute/path
- name: another
path: ../relative/path
## URL
The `url` setting specifies a profile that is located at an HTTP- or HTTPS-based URL. The profile must be accessible via a HTTP GET operation and must be a valid profile archive (zip, tar, tar.gz format). If the download fails, the profile is inaccessible, or not in the correct format, an error is returned.
For example:
depends:
- name: my-profile
url: https://my.domain/path/to/profile.tgz
## git
A `git` setting specifies a profile that is located in a git repository, with optional settings for branch, tag, commit, and version. The source location is translated into a URL upon resolution. This type of dependency supports version indexing via semantic versioning as git tags.
For example:
depends:
- name: git-profile
git: http://url/to/repo
branch: desired_branch
tag: desired_version
commit: pinned_commit
version: semver_via_tags
## Chef Supermarket
A `supermarket` setting specifies a profile that is located in a cookbook hosted on Chef Supermarket. The source location is translated into a URL upon resolution.
2016-09-21 16:58:25 +00:00
For example:
depends:
- name: supermarket-profile
supermarket: supermarket-username/supermarket-profile
Available Supermarket profiles can be listed with `inspec supermarket profiles`.
2016-09-21 16:58:25 +00:00
## Chef Compliance
A `compliance` setting specifies a profile that is located on the Chef Compliance server.
For example:
depends:
- name: linux
compliance: base/linux
You need to `inspec vendor` the profile before uploading it to Chef Compliance version 1.7.7 or newer. The vendor subcommand fetches all dependent profiles and stores them in the `vendor` directory.
2016-09-21 16:58:25 +00:00
## Define in inspec.yml
Use the `depends` setting in the `inspec.yml` file to define any combination of profile dependencies. For example:
depends:
- name: ssh-hardening
supermarket: hardening/ssh-hardening
version: '= 2.0.0'
2016-09-21 16:58:25 +00:00
- name: os-hardening
url: https://github.com/dev-sec/tests-os-hardening/archive/master.zip
- name: ssl-benchmark
git: https://github.com/dev-sec/ssl-benchmark.git
version: '< 2.0'
2016-09-21 16:58:25 +00:00
- name: windows-patch-benchmark
git: https://github.com/chris-rock/windows-patch-benchmark.git
version: '~> 0.6'
2016-09-21 16:58:25 +00:00
- name: linux
compliance: base/linux
## Vendoring Dependencies
When you execute a local profile, the `inspec.yml` file will be read in order to source any profile dependencies. It will then cache the dependencies locally and generate an `inspec.lock` file. If you add or update dependencies in `inspec.yml`, please refresh the lock file by either:
* running `inspec vendor` inside the profile directory; or
* deleting `inspec.lock` before running `inspec exec`

# Profile Inheritance
When a profile is run, it may include controls that are defined in other profiles. Controls may also be required.
This requires an `inspec.yml` dependency to the profile you inherit from.
2016-09-21 16:58:25 +00:00
## include_controls
The `include_controls` keyword may be used in a profile to import all rules from the named profile.
For example, to include controls from the `cis-level-1` profile when running the `cis-fs-2.7` profile:
include_controls 'cis-level-1' do
control "cis-fs-2.7" do
impact 1.0
...
end
To include controls from the `cis-level-1` profile, but skipping two controls within that profile:
include_controls 'cis-level-1' do
skip_control "cis-fs-2.1"
skip_control "cis-fs-2.2"
end
## require_controls
The `require_controls` keyword may be used to load only specific controls from the named profile.
For example, to require that controls `cis-fs-2.1` and `cis-fs-2.2` be loaded from the `cis-level-1` profile:
require_controls 'cis-level-1' do
control "cis-fs-2.1"
control "cis-fs-2.2"
end
## require_resource
By default, all of the resources from a listed dependency are available
for use in your profile. If two of your dependencies provide a resource with
the same name, you can use the `require_resource` DSL function to
disambiguate the two:
require_resource(profile: 'my_dep', resource: 'my_res',
as: 'my_res2')
This will allow you to reference the resource `my_res` from the
profile `my_dep` using the name `my_res2`.

# Profile Attributes
Attributes may be used in profiles to define secrets, such as user names and passwords, that should not otherwise be stored in plain-text in a cookbook. First specify a variable in the control for each secret, then add the secret to a Yaml file located on the local machine, and then run `inspec exec` and specify the path to that Yaml file using the `--attrs` attribute.
For example, a control:
# define these attributes on the top-level of your file and re-use them across all tests!
2016-09-21 16:58:25 +00:00
val_user = attribute('user', default: 'alice', description: 'An identification for the user')
val_password = attribute('password', description: 'A value for the password')
control 'system-users' do
impact 0.8
desc '
This test assures that the user "Bob" has a user installed on the system, along with a
specified password.
'
describe val_user do
it { should eq 'bob' }
end
2016-09-21 16:58:25 +00:00
describe val_password do
it { should eq 'secret' }
end
2016-09-21 16:58:25 +00:00
end
And a Yaml file named `profile-attribute.yml`:
user: bob
password: secret
The following command runs the tests and applies the secrets specified in `profile-attribute.yml`:
$ inspec exec examples/profile-attribute --attrs examples/profile-attribute.yml
See the full example in the InSpec open source repository: https://github.com/chef/inspec/tree/master/examples/profile-attribute
# Profile files
An InSpec profile may contain additional files that can be accessed during tests. This covers use-cases where e.g. a list of ports is provided to be tested.
To access these files, they must be stored in the `files` directory at the root of a profile. They are accessed by their name relative to this folder with `inspec.profile.file(...)`.
Here is an example for reading and testing a list of ports. The folder structure is:
examples/profile
├── controls
│ ├── example.rb
|── files
│ └── services.yml
└── inspec.yml
With `services.yml` containing:
- service_name: httpd-alpha
port: 80
- service_name: httpd-beta
port: 8080
The tests in `example.rb` can now access this file:
my_services = yaml(content: inspec.profile.file('services.yml')).params
my_services.each do |s|
describe service(s['name']) do
it { should be_running }
end
describe port(s['port']) do
it { should be_listening }
end
end
