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.

AWS provides you with S3 as the object storage, where you can store your object files from 1 KB to 5 TB in size at a low cost. It's highly secure, durable, and scalable, and has unlimited capacity. It allows concurrent read/write access to objects by separate clients and applications. You can store any type of file in AWS S3 storage.


AWS keeps multiple copies of all the data stored in the standard S3 storage, which are replicated across devices in the region to ensure durability of 99.999999999%. S3 cannot be used as block storage.

AWS S3 storage is further categorized into three different sections:

  • S3 Standard: This is suitable when we need durable storage for files with frequent access.
  • Reduced Redundancy Storage: This is suitable when we have less critical data that is persistent in nature.
  • Infrequent Access (IA): This is suitable when you have durable data with nonfrequent access. You can opt for Glacier. However, in Glacier you have a very long retrieval time. So, S3 IA becomes a...
