AWS Certified Data Analytics Specialty 2021 – Hands-On - S3 Default Encryption Versus and Bucket Policies

The video tutorial explains the differences between default encryption options and bucket policies in Amazon. It details how bucket policies can enforce encryption by refusing API calls without specified encryption headers, such as AES 256. The tutorial also covers the default encryption option in Amazon, which encrypts objects after upload if they are unencrypted. It emphasizes that bucket policies are evaluated before default encryption, meaning unencrypted objects will be denied if both are set. The lecture concludes with a brief wrap-up.
