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.

Data privacy and security for tenants

OpenStack also provides multitenancy, which means you can have multiple tenants in an OpenStack Cloud. Each tenant has their own set of resources as per their requirement. All of these tenants have their own separate identities in the cloud. So here, data privacy and security is of the utmost importance.

Now, let's understand data privacy concerns for a multitenancy environment and its mitigation:

  • The first concern is related to data privacy, that is, data residency. It says data privacy and isolation is a crucial point, which works as a barrier in the way of cloud adoption. There are many OpenStack services, which record tenant data and metadata. Tenant data includes objects stored in object storage, data stored on ephemeral storage, data stored on block storage, snapshots, public keys, and so on. Metadata includes details such as name, IP, compute information, and size of storage. Here, being a cloud operator, one must take care of all data privacy issues...
