AWS Startup Security Baseline

May 2023 (document history)

The AWS Startup Security Baseline (AWS SSB) is a set of controls that create a minimum foundation for businesses to build securely on AWS without decreasing their agility. These controls form the basis of your security posture and are focused on securing credentials, enabling logging and visibility, managing contact information, and implementing basic data boundaries.

The controls in this guide are designed with early startups in mind, mitigating the most common security risks without requiring significant effort. Many startups begin their journey in the AWS Cloud with a single AWS account. As organizations grow, they migrate to multi-account architectures. The guidance in this guide is designed for single-account architectures, but it helps you set up security controls that are easily migrated or modified as you transition to a multi-account architecture.

The controls in the AWS SSB are separated into two categories: account and workload. Account controls help keep your AWS account secure. It includes recommendations for setting up user access, policies, and permissions, and it includes recommendations for how to monitor your account for unauthorized or potentially malicious activity. Workload controls help secure your resources and code in the cloud, such as applications, backend processes, and data. It includes recommendations such as encryption and reducing the scope of access.

Intended audience

This guide is best suited for startups that are in the very beginning stages of development, with minimal staff and operations.

Startups or other businesses that are in later stages of operation and growth can still derive significant value from reviewing these controls against their current practices. If you identify any gaps, you can implement the individual controls in this guide and then evaluate them for appropriateness as a long-term solution.

Foundational framework and security responsibilities

AWS Well-Architected helps cloud architects build a secure, high-performing, resilient, and efficient infrastructure for their applications and workloads. The AWS Startup Security Baseline aligns to the security pillar of the AWS Well-Architected Framework. The security pillar describes how to take advantage of cloud technologies to protect data, systems, and assets in a way that can improve your security posture. This helps you meet your business and regulatory requirements by following current AWS recommendations.

You can assess your adherence to Well-Architected best practices by using the AWS Well-Architected Tool in your AWS account.

Security and compliance are a shared responsibility between AWS and the customer. The shared responsibility model is often described by saying that AWS is responsible for the security of the cloud (that is, for protecting the infrastructure that runs all the services offered in the AWS Cloud), and you are responsible for the security in the cloud (as determined by the AWS Cloud services that you select). In the shared responsibility model, implementing the security controls in this document is part of your responsibility as a customer.
