We have released a new version of the Well-Architected Framework. We also added new and updated lenses to the Lens Catalog. Learn more
Data protection in AWS Well-Architected Tool
The AWS shared responsibility model
For data protection purposes, we recommend that you protect AWS account credentials and set up individual users with AWS IAM Identity Center or AWS Identity and Access Management (IAM). That way, each user is given only the permissions necessary to fulfill their job duties. We also recommend that you secure your data in the following ways:
-
Use multi-factor authentication (MFA) with each account.
-
Use SSL/TLS to communicate with AWS resources. We require TLS 1.2 and recommend TLS 1.3.
-
Set up API and user activity logging with AWS CloudTrail.
-
Use AWS encryption solutions, along with all default security controls within AWS services.
-
Use advanced managed security services such as Amazon Macie, which assists in discovering and securing sensitive data that is stored in Amazon S3.
-
If you require FIPS 140-3 validated cryptographic modules when accessing AWS through a command line interface or an API, use a FIPS endpoint. For more information about the available FIPS endpoints, see Federal Information Processing Standard (FIPS) 140-3
.
We strongly recommend that you never put confidential or sensitive information, such as your customers' email addresses, into tags or free-form text fields such as a Name field. This includes when you work with AWS WA Tool or other AWS services using the console, API, AWS CLI, or AWS SDKs. Any data that you enter into tags or free-form text fields used for names may be used for billing or diagnostic logs. If you provide a URL to an external server, we strongly recommend that you do not include credentials information in the URL to validate your request to that server.
Encryption at rest
All data stored by AWS WA Tool is encrypted at rest.
Encryption in transit
All data sent to and from AWS WA Tool is encrypted in transit.
How AWS uses your data
The AWS Well-Architected team collects aggregated data from the AWS Well-Architected Tool to provide and improve the AWS WA Tool service for customers. Individual customer data may be shared with AWS account teams to support our customers’ efforts to improve their workloads and architecture. The AWS Well-Architected team can only access workload properties and selected choices for each question. AWS does not share any data from the AWS WA Tool outside of AWS.
