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.

Chapter 7. Security Hardening for Applications and Networks

Security hardening is the most obvious task for any security-conscious endeavor. By doing the effort of securing systems, applications, and networks, one can achieve multiple security goals given as follows:

  • Ensuring that applications and networks are not compromised (sometimes)
  • Making it difficult for compromises to stay hidden for long
  • Securing by default ensures that compromises in one part of the network don't propagate further and more

The Ansible way of thinking about automation around security is a great fit for automating security hardening. In this chapter, we will introduce security benchmarks and frameworks that can be used to build playbooks that will allow us to do the following things:

  • Secure our master images so that as soon as the applications and systems are part of the network, they offer decent security
  • Execute audit processes so that we can verify and measure periodically if the applications, systems, and networks...
