Data Protection in Amazon Cognito - Amazon Cognito

Data Protection in Amazon Cognito

The AWS shared responsibility model applies to data protection in Amazon Cognito (Amazon Cognito). As described in this model, AWS is responsible for protecting the global infrastructure that runs all of the AWS Cloud. You are responsible for maintaining control over your content that is hosted on this infrastructure. This content includes the security configuration and management tasks for the AWS services that you use. For more information about data privacy, see the Data Privacy FAQ.

For data protection purposes, we recommend that you protect AWS account credentials and set up individual user accounts with 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.

  • 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 personal data that is stored in Amazon S3.

We strongly recommend that you never put sensitive identifying information, such as your customers' account numbers, into free-form fields such as a Name field. This includes when you work with Amazon Cognito or other AWS services using the console, API, AWS CLI, or AWS SDKs. Any data that you enter into Amazon Cognito or other services might get picked up for inclusion in diagnostic logs. When you provide a URL to an external server, don't include credentials information in the URL to validate your request to that server.

Data-Encryption

Data encryption typically falls into two categories: encryption at rest and encryption in transit.

Encryption at Rest

Data within Amazon Cognito is encrypted at rest in accordance with industry standards.

Encryption in Transit

All requests to Amazon Cognito must be made over the Transport Layer Security protocol (TLS). Clients must support Transport Layer Security (TLS) 1.0 or later. We recommend TLS 1.2 or later. Clients must also support cipher suites with perfect forward secrecy (PFS) such as Ephemeral Diffie-Hellman (DHE) or Elliptic Curve Ephemeral Diffie-Hellman (ECDHE). Most modern systems such as Java 7 and later support these modes.

Note

Amazon Cognito encrypts customer content internally and doesn't support customer provided keys.
