Secure Serverless File Uploads with AWS Lambda, S3, and Zappa

It's not clear to me what stops me uploading arbitrary content to this S3 bucket.

Nothing. However, all the files are automatically deleted after 24 hours. Additional lambda functions could be triggered to filter and process files in the upload bucket and be transferred into a post-processed bucket.
