AWS: Security Best Practices on AWS

By: Albert Anthony

Overview of this book

With organizations moving their workloads, applications, and infrastructure to the cloud at an unprecedented pace, security of all these resources has been a paradigm shift for all those who are responsible for security; experts, novices, and apprentices alike. This book focuses on using native AWS security features and managed AWS services to help you achieve continuous security. Starting with an introduction to Virtual Private Cloud (VPC) to secure your AWS VPC, you will quickly explore various components that make up VPC such as subnets, security groups, various gateways, and many more. You will also learn to protect data in the AWS platform for various AWS services by encrypting and decrypting data in AWS. You will also learn to secure web and mobile applications in AWS cloud. This book is ideal for all IT professionals, system administrators, security analysts, solution architects, and chief information security officers who are responsible for securing workloads in AWS for their organizations. This book is embedded with useful assessments that will help you revise the concepts you have learned in this book. This book is repurposed for this specific learning experience from material from Packt's Mastering AWS Security, written by Albert Anthony.

VPC


VPC is your own virtual, secured, scalable network in the AWS cloud that contains your AWS resources. Let us look at the VPC security best practices:

  • Create custom VPC: It is recommended to create your own VPC and not use the default VPC as it has default settings to allow unrestricted inbound and outbound traffic.

  • Monitor VPC activity: Create VPC flow logs to monitor flow of all IP traffic in your VPC from network resources to identify and restrict any unwanted activity.

  • Use Network Address Translation (NAT): Keep all your resources that do not need access to the internet in a private subnet. Use a NAT device, such as a NAT instance or NAT gateway to allow internet access to resources in a private subnet.

  • Control access: Use IAM to control access to the VPC and resources that are part of the VPC. You can create a fine grained access control using IAM for resources in your VPC.

  • Use NACL: Configure NACLs to define which traffic is allowed and denied for your VPC through the subnet. Control...
