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.

Neutron – OpenStack network

As we know, OpenStack uses different projects to enable you to deploy to the cloud. The neutron project is responsible for providing network services. It provides tenant facing APIs to define network connectivity and IP addressing for instances.

Neutron enables tenants or users to define the network, manage it, and use the network resources for their services.

OpenStack networking comes with the following components:

  • Neutron server: This runs on the network node to provide networking APIs and its extensions. Neutron plugins let the neutron server access the database via an asynchronous message queue (AMQP).
  • Plugin agent: This runs on compute nodes to manage the local vSwitch and also check which agent is running.
  • DHCP agent: This is used to provide DHCP services for tenants.
  • Neutron L3-agent: This is used to provide external network access to VMs running inside the tenant network.
  • SDN: This service interacts with the neutron server, neutron plugin, and plugin agent.
