Infrastructure security in Resource Groups
There are no additional ways of isolating service or network traffic provided by Resource Groups. If applicable, use AWS-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, AWS Resource Groups is protected by AWS global network security. For information about AWS security services and how AWS protects infrastructure, see AWS Cloud Security
You use AWS 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.
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 AWS Security Token Service (AWS STS) to generate temporary security credentials to sign requests.
Resource Groups does not support resource-based policies.
