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.

Securing Data in Transit


Most of the web applications that are hosted on AWS will be sending data over the internet and it is imperative to protect data in transit. This transit will involve network traffic between clients and servers, and network traffic between servers. So data in transit needs to be protected at the network layer and the session layer.

AWS services provide IPSec and SSL/TLS support for securing data in transit. An IPSec protocol extends the IP protocol stack primarily for the network layer and allows applications on the upper layers to communicate securely without modification. The SSL/TLS, however, operates at the session layer.

The Transport Layer Security (TLS) is a standard set of protocols for securing communications over a network. TLS has evolved from Secure Sockets Layer (SSL) and is considered to be a more refined system.

Let us look at options to secure network traffic in AWS for various AWS services.
