AWS re:Invent 2022 - Revitalize your security with the AWS Security Reference Architecture (SEC203)

Summary

The AWS Security Reference Architecture (AWS SRA) is a comprehensive guide designed to help organizations understand and deploy AWS security services in a multi-account environment.
Sarah Curry, a security practice manager, and Johnny Ray, a senior security engineer, presented the session.
The AWS SRA is built based on customer feedback and aims to address common challenges such as defining security architecture, keeping up with AWS security services, implementing security architecture reliably, and making security approachable for all.
The session covered the importance of defense in depth and provided a castle metaphor to explain how various AWS security services work together to protect an AWS environment.
The AWS SRA is aligned with the AWS shared responsibility model, the Well-Architected Framework, and the Cloud Adoption Framework.
The presenters discussed the AWS SRA's building blocks, including organizational units (OUs), accounts, network and content delivery, AWS principles, and AWS resources.
They provided a customer story to illustrate how the AWS SRA can be applied in practice.
The session also introduced the AWS SRA code repository, which contains infrastructure as code templates for implementing the AWS SRA.
Attendees were given actionable next steps for one week, three months, and six months post-session to assess and improve their security architecture using the AWS SRA.

The AWS SRA is a response to the need for structured guidance in securing AWS environments, especially as organizations scale and adopt a multi-account strategy.
The castle metaphor is an educational tool to make security concepts more relatable and understandable, especially for non-security professionals.
The AWS SRA leverages the concept of defense in depth, emphasizing the importance of multiple layers of security controls.
The AWS SRA is flexible and customizable, allowing organizations to adapt the reference architecture to their specific needs and industry requirements.
Infrastructure as code is a key component of the AWS SRA, enabling fast and reliable deployment of security architectures.
The session highlighted the importance of continuous learning and adaptation in cloud security, given the rapid pace of innovation and new service releases in AWS.
The AWS SRA is positioned as a living document, with AWS actively seeking customer feedback to iterate and improve the architecture over time.
