Amazon DynamoDB: Allows access to specific attributes

This example shows how you might create an identity-based policy that allows access to the specific DynamoDB attributes. This policy grants the permissions necessary to complete this action programmatically from the AWS API or AWS CLI. To use this policy, replace the italicized placeholder text in the example policy with your own information. Then, follow the directions in create a policy or edit a policy.

The dynamodb:Select requirement prevents the API action from returning any attributes that aren't allowed, such as from an index projection. To learn more about DynamoDB condition keys, see Specifying Conditions: Using Condition Keys in the Amazon DynamoDB Developer Guide. To learn about using multiple conditions or multiple condition keys within the Condition block of an IAM policy, see Multiple values in a condition.
