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.

Here, we have the types of VPN connection options available:

  • AWS-managed VPN connection: In AWS-managed VPN connection, we have the following scenario:
    • Between AWS network and other networks: In AWS VPC, we have VGW, which provides two VPN endpoints for automatic failover. And we configure the VPN tunnel between VGW and other networks' firewalls (it can be from any vendor such as Cisco, Juniper, Palo Alto, and Cyberoam). In this case, there will be a single tunnel:

In the preceding diagram, we have a connection between Virtual Private Gateway and Customer Gateway. These are two major components of a VPC connection. To create a VPN Connection, first, we have to create a VGW, which, by default, creates two endpoints. Then, we define the Customer Gateway...
