I want to provide some audio files as a little intro to an Alexa skill. For the sake of simplicity I uploaded them to an S3 bucket. I granted pubic access to make sure it works while testing it. Now as my skills are about to go live, I wonder if it is a good idea to have them publicly accessible.
Can I restrict the access, so that only the skill is allowed to play the sound and not anybody out there with the link?
I fiddled around with the priviledges, but always ended up that it eiher threw an error from the AWS function or was publicly available via the link.
Any idea for the perfect "chmod" settings, like chmod 400, owner can read.
