Lab Details

  1. This lab walks you through the steps to Configure Multi-layered Security in AWS VPC and to launch 2 EC2 instances (one in a public subnet and another in a private subnet)

  2. You will practice it using Amazon VPC, Amazon EC2

  3. Duration: 1 Hour

  4. AWS Region: US East (N. Virginia) us-east-1

Introduction

Amazon Virtual Private Cloud

  1. Amazon VPC allows us to launch AWS resources in an isolated network that is defined by us in a more private and secure environment.

  2. This feature enables us to increase the security level of the AWS resources.

  3. The AWS resources can be protected using multilayered VPC which includes security groups and Network Access Control list.

  4. The VPC security group provides security at instance level which acts like a firewall and controls both inbound and outbound traffic.

  5. The VPC NACL provides security at Network Level i.e subnet level which acts like a firewall for associated subnets and controls inbound and outbound traffic.
