# Understand infrastructure security in Amazon Data Firehose
<a name="infrastructure-security"></a>

As a managed service, Amazon Data Firehose is protected by AWS global network security. For information about AWS security services and how AWS protects infrastructure, see [AWS Cloud Security](https://aws.amazon.com/security/). To design your AWS environment using the best practices for infrastructure security, see [Infrastructure Protection](https://docs.aws.amazon.com/wellarchitected/latest/security-pillar/infrastructure-protection.html) in *Security Pillar AWS Well‐Architected Framework*.

You use AWS published API calls to access Firehose 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.

**Note**  
For outgoing HTTPS requests, Amazon Data Firehose uses an HTTP library that automatically selects the highest TLS protocol version supported at the destination side.
