AWS Security Foundations For Dummies

AWS shared responsibility, demystified:Get a clear breakdown of which security tasks AWS handles—and which ones your team is responsible for—across core AWS services.
Secure identities and permissions by default:Learn how to strengthen IAM, prevent permission sprawl, enforce least privilege, and implement guardrails using AWS-native services like IAM, Organizations, and SCPs.
Cloud-native protection for your AWS workloads:Understand how to secure data at rest and in transit, harden key services, and use monitoring tools to reduce risk without slowing down engineering.

This cheat sheet is designed for:

Cloud security engineers and architects responsible for AWS environments
Platform and DevOps teams securing AWS infrastructure
Compliance and GRC professionals implementing AWS-aligned controls
Anyone working to enforce secure-by-default configurations across AWS services
Teams building, scaling, or migrating workloads in AWS who need practical, easy-to-follow security guidance

What’s included?

AWS security foundations: Understand how AWS divides security responsibilities and what actions customers must take to secure their part of the environment.
Securing AWS infrastructure: Learn how to apply zero-trust principles across hosts, applications, and networks to build a resilient, defense-in-depth architecture.
Identity and permissions protection: Explore best practices and tools for managing users, roles, and access to ensure people only reach the resources they should — and nothing more.
Monitoring, defense, and incident response: Get practical guidance on detecting threats, protecting sensitive data, responding to incidents, and staying calm and prepared in fast-moving cloud environments.
