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.

Quick recap

In AWS, we have VPC. It's an isolated boundary under which your infrastructure resides and your application runs. At VPC level, we defined subnets to further isolate traffic by defining DMZ and MZ zones.

NACL and security groups are used to define ingress and egress traffic. The NACL rule works on the basis of sequence number.

To connect the AWS Cloud with on-premise infrastructure, we have the following different methods:

  • VPN connections: In a VPN connection, we create a site-to-site VPN tunnel between an on-premise infrastructure and AWS using customer gateway and VGW. AWS supports almost all the available firewalls on the market for VPN connections.
  • Direct Connect: If you want to transfer massive amounts of data to and from the AWS public cloud, there is Direct Connect, which offers a dedicated network connection between the AWS data center and your on-premise infrastructure. If you need to ensure encryption on your direct connection too, you need to create a VPN tunnel between...
