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.

In the OpenStack project, object storage is provided by Swift, which provides highly available, scalable, distributed, and eventually consistent data storage. It supports the HTTP protocol using APIs and HTTPS to communicate with object storage.

Object storage (Swift) stores data in the hierarchy in which the top layer is the account. Here, the storage provider creates an account for you and you become the owner of this account. 

After that, the second layer is the container. The container actually defines the namespace of the object. Namespace helps you to create isolation. For example, you have two objects with the same name and both reside in two different containers; here both will have unique identities.

Apart from this, the container also creates ACL to control the object.

At the bottom, we have the object layer where we store our objects such as documents and images. We can also associate metadata with the object. 

Object storage has the following additional...
