Cookbook Version Build Status

Requirements

Chef

  • Chef Client >=12.5.1

The audit cookbook allows you to run Chef Compliance profiles as part of a Chef Client run. It downloads configured profiles from Chef Compliance and reports audit runs to Chef Compliance.

Chef Compliance and InSpec

Using the inspec_version attribute, please use the following InSpec version based on your Chef Compliance version:

Chef Compliance version InSpec version Audit Cookbook version
Less or equal to 1.1.23 0.20.1 0.7.0
Greater than 1.1.23 Greater or equal to 0.22.1 0.8.0

You can see all publicly available InSpec versions here

Overview

The audit support two scenarios:

Chef Server Integration

The first scenario requires at least Chef Compliance 1.0 and the Chef Server extensions for Compliance. The architecture looks as following:

 ┌──────────────────────┐    ┌──────────────────────┐    ┌──────────────────────┐

 └──────────────────────┘    └──────────────────────┘    └──────────────────────┘

Chef Compliance

The second scenario support a direct connection with Chef Compliance and support chef-solo mode as well.

  audit = {
    "inspec_version" => "0.22.1",
  }

Usage

The audit cookbook needs to be configured for each node where the chef-client runs. The audit cookbook can be reused for all nodes, all node-specific configuration is done via Chef attributes.

Upload cookbook to Chef Server

The audit cookbook is available at Chef Supermarket. This allows you to reuse the existing workflow.

If you want to upload the cookbook from git, use the following commands:

mkdir chef-cookbooks
cd chef-cookbooks
git clone https://github.com/chef-cookbooks/audit
cd ..
knife cookbook upload audit -o ./chef-cookbooks

Please ensure that chef-cookbooks is the parent directory of audit cookbook.

Configure node

Once the cookbook is available in Chef Server, you need to add the audit::default recipe to the run-list of each node. The profiles are selected via the node['audit']['profiles'] attribute. For example, to run the base/ssh and base/linux profiles, you can define the attribute in a JSON-based role or environment file like this:

audit = {
  "inspec_version" => "0.22.1",
  "profiles" => {
    # org / profile name from Chef Compliance
    'base/linux' => true,
    # supermarket url
    'brewinc/ssh-hardening' => {
      # location where inspec will fetch the profile from
      'source' => 'supermarket://hardening/ssh-hardening',
      'key' => 'value',
    },
    # local Windows path
    'brewinc/win2012_audit' => {
      # filesystem path
      'source' => 'E:/profiles/win2012_audit',
    },
    # github url
    'brewinc/tmp_compliance_profile' => {
      'source' => 'https://github.com/nathenharvey/tmp_compliance_profile',
    },
    # disable profile
    'brewinc/tmp_compliance_profile-master' => {
      'source' => '/tmp/tmp_compliance_profile-master',
      'disabled' => true,
    },
  },
}

Direct reporting to Chef Compliance

If you want the audit cookbook directly report to Chef Compliance, set the server and the token attribute.

If those attributes are missing, the audit cookbook expects the Chef Server integration to be available.

audit: {
  server: 'https://compliance-fqdn/api/',
  token: 'eyJ........................YQ',
  profiles: {
    'base/windows'    => true,
  },
}

It is also possible to use a refresh_token instead of an access token:

audit: {
  server: 'https://compliance-fqdn/api/',
  refresh_token: '5/4T...g==',
  profiles: {
    'base/windows'    => true,
  },
}

How does it relate to Chef Audit Mode

The following tables compares the Chef Client audit mode with this audit cookbook.

audit mode audit cookbook
Works with Chef Compliance No Yes
Execution Engine Serverspec InSpec
Execute InSpec Compliance Profiles No Yes
Execute tests embedded in Chef recipes Yes No

How to migrate from audit mode to audit cookbook:

We will improve the migration and help to ease the process and to reuse existing audit mode test as much as possible. At this point of time, an existing audit-mode test like:

control_group 'Check SSH Port' do
  control 'SSH' do
    it 'should be listening on port 22' do
      expect(port(22)).to be_listening
    end
  end
end

can be re-written in InSpec as follows:

# rename `control_group` to `control` and use a unique identifier
control "blog-1" do
  title 'Check SSH Port'  # add the title from `control_group`
  # rename the old `control` to `describe`
  describe 'SSH' do
    it 'should be listening on port 22' do
      expect(port(22)).to be_listening
    end
  end
end

or even simplified to:

control "blog-1" do
  title 'SSH should be listening on port 22'
  describe port(22) do
    it { should be_listening }
  end
end

Interval Settings

If you have long running audit profiles that you don't wish to execute on every chef-client run,
you can use the interval recipe instead of the default recipe in your runlist, and set the
following attributes:

default['audit']['interval']['enabled'] = false
default['audit']['interval']['time'] = 1440

The time attribute is in minutes.

You can enable the interval and set the interval time, along with your desired profiles,
in an environment or role like this:

  "audit": {
    "profiles": {
      "base/ssh": true,
      "base/linux": true
    },
    "interval": {
      "enabled": "true",
      "time": 1440
    }
  }

Please let us know if you have any issues, we are happy to help.
