Checklist Summary:

This document provides prescriptive guidance for establishing a secure operational posture for a three-tier Web architecture deployed to the Amazon Web Services environment. Notionally, the three-tier Web architecture consists of a single Virtual Private Cloud (VPC) within a single AWS account. The recommendations made in the CIS AWS Foundations Benchmark should be followed prior to completing these recommendations. This benchmark covers the necessary AWS configurations to establish ongoing operations of a three-tier Web architecture. Specific Amazon Web Services in scope for this document include: Elastic Compute Cloud (EC2) - API Version 2016-04-01 Virtual Private Cloud (VPC) - API Version 2016-04-01 Identity and Access Management (IAM) - API Version 2010-05-08 AWS Config - API Version 2014-11-12 CloudFront CDN - API Version 2016-01-13 CloudWatch - API Version 2010-08-01 Amazon Relational Database Service (RDS) - API Version 2014-10-31 Simple Notification Service (SNS) - API Version 2010-03-31 AWS Certificate Manager (ACM) - API Version 2015-12-08 Key Management Service (KMS) - API Version 2014-11-01 While this Benchmark explicitly covers 3-tier architectures featuring Internet, Application and Database tiers (with a Content Distribution Network in the form of CloudFront, which could be considered a fourth tier), the tiers and the interactions between them are readily generalisable to larger “n-tier” architectures incorporating further tiers such as service proxy and management tiers. In particular, Security Group, routing, subnetting and VPC considerations and configurations can be re-used for further tiers and the segregation of communication between these tiers and others.
