AWS Certified Data Analytics Specialty 2021 - Hands-On! - Amazon Simple Storage Service (Amazon S3) Security and Bucket

The video tutorial explains how to create and test an AWS S3 bucket policy that enforces encryption. It covers using the AWS policy generator to define a policy that denies uploads of unencrypted objects. The tutorial also demonstrates testing the policy with different encryption settings and discusses additional security settings like blocking public access and using ACLs.

What is the primary goal of the bucket policy discussed in the video?

• To prevent uploading objects that are not encrypted

• To allow public access to all objects

• To delete objects automatically after a certain period

• To enable versioning for all objects

Which action is used in the bucket policy to control file uploads?

• GetObject

• PutObject

• ListBucket

• DeleteObject

What condition is checked to deny uploads in the bucket policy?

• If the encryption header is null

• If the file type is not allowed

• If the file size is too large

• If the file name contains special characters

What happens when a file is uploaded without specifying any encryption setting?

• The upload succeeds with default encryption

• The file is encrypted with a random key

• The upload is denied due to the bucket policy

• The file is automatically deleted

How does the bucket policy respond to a file uploaded with KMS encryption?

• The upload is allowed

• The upload is denied

• The file is stored without encryption

• The file is encrypted with AES-256

What is the purpose of the 'block all public access' setting in AWS S3?

• To allow public access to all objects

• To prevent data leaks from S3 into the world

• To enable versioning for all objects

• To delete objects automatically after a certain period

What is an ACL in the context of AWS S3?

• A tool for encrypting objects

• A way to automatically delete objects

• A method to define read and write permissions at the object level

• A setting to block all public access
