What is the best way to give mobile devices permissions to read from DynamoDB? Create an IAM role that can be assumed by an app that allows federated users. Explanation: Web identity federation removes the need for creating individual IAM users.
How DynamoDB encrypts all data by default and provides fine-grained identity and access control on all your tables?
DynamoDB encrypts at rest all user data stored in tables, indexes, streams, and backups using encryption keys stored in AWS Key Management Service (AWS KMS) . This provides an additional layer of data protection by securing your data from unauthorized access to the underlying storage .
What is fine-grained access control?

Use the DynamoDB Encryption Client for client-side encryption, in which you encrypt your table data before you send it to DynamoDB. You may choose to do this based on your data’s sensitivity and your application’s security requirements. For more information, see Client-Side and Server-Side Encryption.
Is DynamoDB encrypted in transit?
With server-side encryption, your data is encrypted in transit over an HTTPS connection, decrypted at the DynamoDB endpoint, and then re-encrypted before being stored in DynamoDB. Encryption by default. DynamoDB transparently encrypts and decrypts all tables when they are written to disk.
