# Infrastructure Security in Amazon Resource Groups
<a name="infrastructure-security"></a>

There are no additional ways of isolating service or network traffic provided by Resource Groups. If applicable, use Amazon-specific isolation. You can use the Resource Groups API and console in a VPC to help maximize privacy and infrastructure security.

As a managed service, Amazon Resource Groups is protected by 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 Resource Groups 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.

Resource Groups does not support resource-based policies.
