Note
The aggregation Region is now called the home Region. Some Security Hub API operations still use the older term aggregation Region.
You can view the current cross-Region aggregation configuration in AWS Security Hub from any AWS Region. The configuration includes the home Region, the linked Regions (if any), and whether to automatically link new Regions as Security Hub supports them.
Member accounts can view the cross-Region aggregation settings that the administrator account configured.
Choose your preferred method, and follow the steps to view your current cross-Region aggregation settings.
To view cross-Region aggregation settings (console)
Open the AWS Security Hub console at https://console.aws.amazon.com/securityhub/
. On the navigation pane, choose Settings and then the Regions tab.
If cross-Region aggregation is not enabled, then the Regions tab displays the option to enable cross-Region aggregation. Only administrator accounts and standalone accounts can enable cross-Region aggregation.
If cross-Region aggregation is enabled, then the Regions tab displays the following information:
-
The home Region
-
Whether to automatically aggregate findings, insights, control statuses, and security scores from new Regions that Security Hub supports and that you opt into
-
The list of linked Regions (if any are selected)
