Guidance for Baseline Security Assessment on AWS

I'm ready to deploy

Overview

This Guidance helps customers assess their foundational security setup in their AWS account. Use the provided AWS CloudFormation template to automate the assessment of your AWS accounts for security vulnerabilities and deliver an assessment report that includes steps on how to resolve the issues. 

How it works

These technical details feature an architecture diagram to illustrate how to effectively use this solution. The architecture diagram shows the key components and their interactions, providing an overview of the architecture's structure and functionality step-by-step.

Well-Architected Pillars

The architecture diagram above is an example of a Solution created with Well-Architected best practices in mind. To be fully Well-Architected, you should follow as many Well-Architected best practices as possible.

For secure authentication and authorization, Lambda is granted access to AWS services on the least privilege basis with read-only permissions. Single Lambda functions are deployed in this guidance and are inaccessible from the internet. The customer can view and download an assessment report within the AWS Well-Architected portal, which can only be accessed by logging into the customer's account. No additional data is stored anywhere else in the customer’s account.

Read the Security whitepaper

Lambda utilizes logs and metrics which are sent to Amazon CloudWatch where the data is analyzed for risks. Using a single CloudFormation template allows customers to easily install and uninstall resources.

Read the Reliability whitepaper

Lambda is purpose built for this Guidance, allowing the customer to change the custom lens and modify the Lambda function to meet their security needs. 

Read the Performance Efficiency whitepaper

Using only the minimum resources required, this Guidance scales to meet demand by using serverless services to deliver the security assessment. Costs are incurred only for the resources consumed.

Read the Cost Optimization whitepaper

This Guidance uses fully managed serverless services that scale with demand, and allow customers to continually match their loads using only the minimum resources required.
