Hi, I'm experimenting with notifications for S3 buckets. I got it working with notifications to HTTP(S) endpoints. What I did: Create a topic: # cat create_topic.data Action=CreateTopic &Name=topictest2 &Attributes.entry.1.key=verify-ssl&Attributes.entry.1.value=false &Attributes.entry.2.key=use-ssl&Attributes.entry.2.value=false &Attributes.entry.3.key=OpaqueData&Attributes.entry.3.value=Hallodrio &Attributes.entry.4.key=push-endpoint&Attributes.entry.4.value=http://helper.example.com/cgi-bin/topictest &Attributes.entry.5.key=persistent&Attributes.entry.5.value=false &Attributes.entry.6.key=cloudevents&Attributes.entry.6.value=false # curl --request POST 'https://rgw.example.com' --data @create_topic.data <CreateTopicResponse xmlns="https://sns.amazonaws.com/doc/2010-03-31/"><CreateTopicResult><TopicArn>arn:aws:sns:example::topictest2</TopicArn></CreateTopicResult><ResponseMetadata><RequestId>f0904533-f4ed-4d60-886c-4125fcbed97b.4944109.3169009808426767767</RequestId></ResponseMetadata></CreateTopicResponse> And then created a notification for some user, which I received ok via http. What I'm wondering: There was no authentication/authorization necessary at all to create the topic?? Is that normal? Any <...> could create a million topics that way. Is there a way to prevent that from happening? I haven't found one in the docs. I guess - being new to the topic of notifications - that I'm missing something obvious?
