Description

Messages in SQS queue are not encrypted at the moment. Consider using SSE to encrypt messages.

https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-server-side-encryption.html

Motivation

Encrypt messages at rest (while they are sitting in the queue).

Considerations

• KMS does cost money (make it an opt in)
• Setting up SSE may limit the number queues that can be made
