AWS Transit Gateway
Connecting Transit Gateway Flow logs to your Panther Console
Panther supports ingesting Amazon Web Services (AWS) Transit Gateway Flow logs via AWS S3.
To pull Transit Gateway logs into Panther, you need to set up an S3 bucket in the Panther Console to stream data from your AWS account.
- 1.Log in to your Panther Console.
- 2.In the left sidebar menu, click Configure > Log Sources.
- 3.Click Create.
- 4.Search "AWS" to see the list of available log sources.
- 5.Select AWS Transit Gateway Flow.
- 6.Select AWS S3 Bucket for your source to begin setup. Follow Panther’s documentation for configuring S3 for data transport.
TransitGatewayFlow logs enable you to capture information about the IP traffic going to and from your transit gateways. For more information, see AWS's documentation on Transit Gateway Flow Logs.
