In DynamoDB, could you use IAM to grant access to Amazon DynamoDB resources and API actions?

Amazon DynamoDB integrates with AWS Identity and Access Management (IAM). You can use AWS IAM to grant access to Amazon DynamoDB resources and API actions.

You then attach that policy to an AWS IAM user or role. http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/UsingIAMWithDDB.html
