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.

AWS offers services to handle the cache management process. Earlier, we were using Memcached or Redis installed on VM, which was a very complex and tough task to manage in terms of ensuring availability, patching, scalability, and security.

On AWS, we have this service available as ElastiCache. This gives you the option to use any engine (Redis or Memcached) to manage your cache. It's a scalable platform that will be managed by AWS in the backend.

ElastiCache provides a scalable and high-performance caching solution. It removes the complexity associated with creating and managing distributed cache clusters using Memcached or Redis.

Now, let's look at how to secure ElastiCache.

Securing ElastiCache

For enhanced security, we deploy ElastiCache clusters inside VPC. When they are deployed inside VPC, we can use a security group and NACL to add a level of security on the communication ports at network level.

Apart from this, there are multiple ways to enable security for ElastiCache.
