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.

EBS is block-level storage provided by AWS. It can be used as an operating system disk and a data storage disk for EC2 instances. It's network attached storage, which persists independently from your data from the life of the instance. For this, we need to specify it while creating the EC2 instance.

EBS can be used as a separate physical hard drive, where you can specify the filesystem of your own choice after formatting and use the file I/O interface provided by the EC2 instance operating system.

EBS also works as the boot volume for EBS-based AMIs. You can attach multiple EBS volumes to EC2 instances. However, one volume can only be attached to one instance at a time.

EBS also provides you with the ability to create point-in-time snapshots of volumes that are then stored in S3.

Let's see how we can enable data security at the EBS level.

Fault tolerance at EBS

As we know, EBS can be attached to an instance as a physical volume. Here, we can define the redundant array of independent disk ...
