Amazon's SQS service is built securely. It requires credentials to initiate any request to SQS queues. Even if you supply credentials while initiating a request to a queue, you may not be able to access it unless you have sufficient permission to access the queues and messages. In this section, let's look at authentication and access control related to SQS queues.
AWS allows you to access SQS with any of the following identities:
- Root user
- IAM user
- IAM role
- Federated access
- Cross-account access
- AWS service access
- EC2 applications
Sometimes, it becomes necessary to protect your data using the SSE due to some compliance requirement or due to the criticality of the data used in the SQS queue. Amazon provides SSE to protect sensitive data in SQS. SSE helps you to transmit sensitive data in encrypted queues. Amazon uses KMS to manage encryption keys. These keys are used for encrypting the queue.
Messages are encrypted by SSE as soon as the messages are added to the queue...
