This document provides an overview of AWS security best practices. It recommends taking a prescriptive approach to: understand the AWS security model, build strong compliance foundations through programs like SOC and PCI certifications, integrate identity and access management using IAM, enable detective controls with services like CloudTrail and CloudWatch, establish network security using VPC and security groups, implement data protection with encryption services, optimize change management with Config and CloudFormation, and automate security functions using partners from the AWS Marketplace. The document emphasizes that security is a shared responsibility between AWS and customers and provides resources for security training.

6. Making life easier
Choosing security does not mean giving up
on convenience or introducing complexity

7. Security ownership as part of DNA
• Promotes culture of “everyone is an owner” for security
• Makes security a stakeholder in business success
• Enables easier and smoother communication

Security architecture can now be part of the ‘maker’ team
Architecture artifacts
(design choices, narrative,
etc.) committed to common
repositories
Complete solutions account
