# AWS::SecurityLake::Subscriber AwsLogSource
<a name="aws-properties-securitylake-subscriber-awslogsource"></a>

Adds a natively supported Amazon service as an Amazon Security Lake source. Enables source types for member accounts in required Amazon Regions, based on the parameters you specify. You can choose any source type in any Region for either accounts that are part of a trusted organization or standalone accounts. Once you add an Amazon service as a source, Security Lake starts collecting logs and events from it.
