How to set up the AWS Macie feed

1. Click the Amazon Cloud Platformpack.
2. Locate the AWS Macielog type.

3. Specify the values in the following fields.

   • Source Type: Amazon SQS V2
   • Queue Name: The SQS queue name to read from
   • S3 URI: The bucket URI.
     • s3://your-log-bucket-name/
       • Replace your-log-bucket-name with the actual name of your S3 bucket.

   • Source deletion options: Select the deletion option according to your ingestion preferences.

   • Maximum File Age: Include files modified in the last number of days. Default is 180 days.

   • SQS Queue Access Key ID: An account access key that is a 20-character alphanumeric string.

   • SQS Queue Secret Access Key: An account access key that is a 40-character alphanumeric string.

   Advanced options

   • Feed Name: A prepopulated value that identifies the feed.
   • Asset Namespace: Namespace associated with the feed.
