# Amazon SNS access control use cases
Access control use cases

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](sns-access-policy-use-cases.md#sns-grant-aws-account-access-to-topic).
+ You want to limit subscriptions to your topic to only the HTTPS protocol. For more information, see [Limit subscriptions to HTTPS](sns-access-policy-use-cases.md#sns-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](sns-access-policy-use-cases.md#sns-publish-messages-to-sqs-queue).
