Cloud Security Automation

By: Prashant Priyam

Overview of this book

Security issues are still a major concern for all IT organizations. For many enterprises, the move to cloud computing has raised concerns for security, but when applications are architected with focus on security, cloud platforms can be made just as secure as on-premises platforms. Cloud instances can be kept secure by employing security automation that helps make your data meet your organization's security policy. This book starts with the basics of why cloud security is important and how automation can be the most effective way of controlling cloud security. You will then delve deeper into the AWS cloud environment and its security services by dealing with security functions such as Identity and Access Management and will also learn how these services can be automated. Moving forward, you will come across aspects such as cloud storage and data security, automating cloud deployments, and so on. Then, you'll work with OpenStack security modules and learn how private cloud security functions can be automated for better time- and cost-effectiveness. Toward the end of the book, you will gain an understanding of the security compliance requirements for your Cloud. By the end of this book, you will have hands-on experience of automating your cloud security and governance.

Chapter 5. Cloud Storage and Data Security

Until now, we have seen the different security options and methodologies that are available in AWS to ensure the security of your application, infrastructure, and data.

In this chapter, we will dive deep into data security. So, before going into the security aspect, let's look at the kind of storage we have in AWS.

In AWS, we have the following two categories of storage:

  • Ephemeral: This is volatile in nature. It stores data temporarily but ensures very high performance. Ephemeral storage comes with EC2 instances. We also call it the instance store. The basic reason behind using ephemeral storage is to store the cache in transaction data, which changes very frequently. We cannot store any critical data in ephemeral storage.
  • Persistent: This is used to store the data you want to access from time to time for operational purposes. For persistent storage, we have the Elastic Block Store (EBS). Here, you can choose a disk category that is suitable for your...
