# Data protection in Amazon Resource Explorer
<a name="data-protection"></a>

The Amazon [shared responsibility model](https://www.amazonaws.cn/compliance/shared-responsibility-model/) applies to data protection in Amazon Resource Explorer. As described in this model, Amazon is responsible for protecting the global infrastructure that runs all of the Amazon Web Services 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 Amazon Web Services services that you use. For more information about data privacy, see [Amazon China Region Legal Terms](https://www.amazonaws.cn/legal/). 

For data protection purposes, we recommend that you protect Amazon Web Services account credentials and set up individual users with Amazon IAM Identity Center or Amazon 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 Amazon resources. We require TLS 1.2 and recommend TLS 1.3.
+ Set up API and user activity logging with Amazon CloudTrail. For information about using CloudTrail trails to capture Amazon activities, see [Working with CloudTrail trails](https://docs.amazonaws.cn/awscloudtrail/latest/userguide/cloudtrail-trails.html) in the *Amazon CloudTrail User Guide*.
+ Use Amazon encryption solutions, along with all default security controls within Amazon Web Services 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 Amazon 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](https://www.amazonaws.cn/compliance/fips/).

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 Resource Explorer or other Amazon Web Services services using the console, API, Amazon CLI, or Amazon 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

Data that is stored by Resource Explorer includes the indexed list of the resources and their associated ARNs that are used by the customer and the views to access them.

This data is encrypted when at rest by using [Amazon Key Management Service (Amazon KMS) symmetric encryption keys](https://docs.amazonaws.cn/kms/latest/developerguide/asymmetric-key-specs.html#key-spec-symmetric-default) that implement the [Advanced Encryption Standard (AES)](https://csrc.nist.gov/csrc/media/publications/fips/197/final/documents/fips-197.pdf) in [Galois Counter Mode (GCM)](http://csrc.nist.gov/publications/nistpubs/800-38D/SP-800-38D.pdf) with 256-bit keys (AES-256-GCM).

## Encryption in transit
<a name="encryption-transit"></a>

Customer requests and all associated data is encrypted in transit using [Transport Later Security (TLS) 1.2](https://datatracker.ietf.org/doc/html/rfc5246) or later. All Resource Explorer endpoints support HTTPS for encrypting data in transit. For a list of Resource Explorer service endpoints, see [Amazon Resource Explorer endpoints and quotas](https://docs.amazonaws.cn/general/latest/gr/resourceexplorer2.html) in the *Amazon Web Services General Reference*.
