Data protection in Amazon EventBridge

The AWS shared responsibility model applies to data protection in Amazon EventBridge. 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. You are also responsible for 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 information about data protection in Europe, see the AWS Shared Responsibility Model and GDPR blog post on the AWS Security Blog.

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 140-2 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) 140-2.

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 EventBridge 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.

Data encryption in EventBridge

EventBridge provides both encryption at rest and encryption in transit to protect your data:

• Encryption at rest

  EventBridge integrates with AWS Key Management Service (KMS) to encrypt stored data. By default, EventBridge uses an AWS owned key to encrypt event data. You can also specify for EventBridge to use a customer managed key for the following instead.

  • Event buses: custom and partner events

• Encryption in transit

  EventBridge encrypts data that passes between EventBridge and other services by using Transport layer Security (TLS).

  For event buses, this includes during an event being sent to EventBridge, as well as when EventBridge sends an event to a rule target.
