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.

A quick recap

In this chapter, we have learned about different storage options in AWS and their usability.

In short, we have following storage options in AWS—for EC2 instances:

  • Ephemeral storage or instance store
  • EBS

For security at the EC2 level, we can ensure data security and safety using encryption, snapshots, and by defining RAID.

Defining encryption at the volume level does impact your application's code, but if we take a snapshot of an encrypted volume, that also becomes encrypted. It encrypts data at rest and data transition between volumes and instances.

Defining RAID gives you fault tolerance at the volume level.

Ephemeral storage, or instance store, is high-performance volatile storage that is used to store temporary data. So, it is always advisable to store persistent data into a persistent volume.

For static content, we have S3 storage, which is object storage with unlimited capacity.  To ensure the security of S3 storage, we have multiple options, such as defining an IAM policy, S3...
