# Infrastructure Security for this Amazon Product or Service
<a name="infrastructure-security"></a>

This Amazon product or service uses managed services, and therefore is protected by the Amazon global network security. For information about Amazon security services and how Amazon protects infrastructure, see [Amazon Cloud Security](https://www.amazonaws.cn/security/). To design your Amazon environment using the best practices for infrastructure security, see [Infrastructure Protection](https://docs.amazonaws.cn/wellarchitected/latest/security-pillar/infrastructure-protection.html) in *Security Pillar Amazon Well‐Architected Framework*.

You use Amazon published API calls to access this Amazon Product or Service through the network. Clients must support the following:
+ Transport Layer Security (TLS). We require TLS 1.2 and recommend TLS 1.3.
+ Cipher suites with perfect forward secrecy (PFS) such as DHE (Ephemeral Diffie-Hellman) or ECDHE (Elliptic Curve Ephemeral Diffie-Hellman). Most modern systems such as Java 7 and later support these modes.

Additionally, requests must be signed by using an access key ID and a secret access key that is associated with an IAM principal. Or you can use the [Amazon Security Token Service](https://docs.amazonaws.cn/STS/latest/APIReference/Welcome.html) (Amazon STS) to generate temporary security credentials to sign requests.

This Amazon product or service follows the [shared responsibility model](http://www.amazonaws.cn/compliance/shared-responsibility-model/) through the specific Amazon Web Services (Amazon) services it supports. For Amazon service security information, see the [Amazon service security documentation page](https://docs.amazonaws.cn/security/?id=docs_gateway#aws-security) and [Amazon services that are in scope of Amazon compliance efforts by compliance program](http://www.amazonaws.cn/compliance/services-in-scope/).
