When to use access control

You have a great deal of flexibility in how you grant or deny access to a resource. However, the typical use cases are fairly simple:

• You want to grant another AWS account a particular type of topic action (for example, Publish). For more information, see Grant AWS account access to a topic.

• You want to limit subscriptions to your topic to only the HTTPS protocol. For more information, see Limit subscriptions to HTTPS.

• You want to allow Amazon SNS to publish messages to your Amazon SQS queue. For more information, see Publish messages to an Amazon SQS queue.
