Security Automation with Ansible 2

By: Akash Mahajan, MADHU AKULA

Overview of this book

Security automation is one of the most interesting skills to have nowadays. Ansible allows you to write automation procedures once and use them across your entire infrastructure. This book will teach you the best way to use Ansible for seemingly complex tasks by using the various building blocks available and creating solutions that are easy to teach others, store for later, perform version control on, and repeat. We’ll start by covering various popular modules and writing simple playbooks to showcase those modules. You’ll see how this can be applied over a variety of platforms and operating systems, whether they are Windows/Linux bare metal servers or containers on a cloud platform. Once the bare bones automation is in place, you’ll learn how to leverage tools such as Ansible Tower or even Jenkins to create scheduled repeatable processes around security patching, security hardening, compliance reports, monitoring of systems, and so on. Moving on, you’ll delve into useful security automation techniques and approaches, and learn how to extend Ansible for enhanced security. While on the way, we will tackle topics like how to manage secrets, how to manage all the playbooks that we will create and how to enable collaboration using Ansible Galaxy. In the final stretch, we’ll tackle how to extend the modules of Ansible for our use, and do all the previous tasks in a programmatic manner to get even more powerful automation frameworks and rigs.

Working with Ansible Vault


Ansible Vault is a command line utility, by default installed along with Ansible. It allows us to encrypt secrets such as keys, credentials, passwords, and so on to include in our playbooks. By doing this, we can also use these encrypted files to share with others as they contain password protection to access the encrypted data. We can use this feature to encrypt our variables, templates, and files inside our playbooks.

Ansible version 2.3 supports encrypting single variables using an Ansible single encrypted variable with the !vault  tag. We will see some examples of how we will use this in our playbooks in next section.

As this is a very simple and powerful way to store and manage secret data, it's really important to use Ansible Vault to store all the secret information in our playbooks.

Some of the really good use cases include how we can use these playbooks without changing...
