# AWS Lambda: Allows a Lambda function to access an Amazon DynamoDB table
Lambda: Service access to DynamoDB

This example shows how you might create an identity-based policy that allows read and write access to a specific Amazon DynamoDB table. The policy also allows writing log files to CloudWatch Logs. 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](access_policies_create.md) or [edit a policy](access_policies_manage-edit.md).

To use this policy, attach the policy to a Lambda [service role](id_roles_create_for-service.md). A service role is a role that you create in your account to allow a service to perform actions on your behalf. That service role must include AWS Lambda as the principal in the trust policy. For details about how to use this policy, see [How to Create an AWS IAM Policy to Grant AWS Lambda Access to an Amazon DynamoDB Table](https://aws.amazon.com/blogs/security/how-to-create-an-aws-iam-policy-to-grant-aws-lambda-access-to-an-amazon-dynamodb-table/) in the AWS Security Blog.
