Amazon Virtual Private Cloud launches new security group sharing features

AWS has introduced new security group management features to enhance security and simplify configuration. With Security Group VPC Associations, a single security group can now be associated with multiple VPCs within an account. In a shared VPC environment, Shared Security Groups enables sharing of security groups with participant accounts, ensuring consistent traffic filtering rules across workloads and accounts. These features provide greater control over network traffic, improve security posture, and reduce administrative overhead for managing security groups. They are available in all commercial AWS Regions, GovCloud Regions, and China Regions. For further details, refer to the Shared Security Groups and Security Groups VPC Association documentation provided in the resources section.
