Finding
The `AWS::SecurityHub::FindingAggregator` resource enables cross-Region aggregation. When cross-Region aggregation is enabled, you can aggregate findings, finding updates, insights, control compliance statuses, and security scores from one or more linked Regions to a single aggregation Region. You can then view and manage all of this data from the aggregation Region. For more details about cross-Region aggregation, see Cross-Region aggregation in the User Guide This resource must be created in the Region that you want to designate as your aggregation Region. Cross-Region aggregation is also a prerequisite for using central configuration in ASH.
Properties
The home Region. Findings generated in linked Regions are replicated and sent to the home Region.
The ARN of the finding aggregator. You use the finding aggregator ARN to retrieve details for, update, and delete the finding aggregator.
Indicates whether to aggregate findings from all of the available Regions in the current partition. Also determines whether to automatically aggregate findings from new Regions as Security Hub supports them and you opt into them. The selected option also determines how to use the Regions provided in the Regions list. The options are as follows:
If `RegionLinkingMode` is `ALL_REGIONS_EXCEPT_SPECIFIED`, then this is a space-separated list of Regions that do not aggregate findings to the aggregation Region. If `RegionLinkingMode` is `SPECIFIED_REGIONS`, then this is a space-separated list of Regions that do aggregate findings to the aggregation Region. An `InvalidInputException` error results if you populate this field while `RegionLinkingMode` is `NO_REGIONS`.
