AWS Certified Data Analytics Specialty 2021 – Hands-On - S3 Security: Bucket Policy Hands-On

This video tutorial explains how to create and test an AWS S3 bucket policy to ensure that only encrypted objects are uploaded. It covers using the AWS Policy Generator to define policies in JSON format, setting conditions for server-side encryption, and testing the policy with different encryption settings. Additionally, it discusses other security settings like blocking public access and using Access Control Lists (ACLs).

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

• To delete objects automatically after a certain period

• To allow public access to all objects

• To prevent uploading unencrypted objects

• To enable versioning for all objects

Which policy type should be selected when creating an S3 bucket policy?

• Lambda Policy

• S3 Bucket Policy

• IAM Policy

• VPC Policy

What action is specified in the bucket policy to deny unencrypted uploads?

• LIST objects

• GET objects

• DELETE objects

• PUT objects

What condition is checked to ensure that an object is encrypted using the SSCS 3 scheme?

• The server-side encryption header must be present

• The object size must be less than 1 MB

• The object must have a specific tag

• The object must be uploaded during business hours

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

• The upload succeeds with a warning

• The upload is denied due to the bucket policy

• The file is automatically encrypted with default settings

• The file is uploaded but marked as insecure

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

• To prevent data leaks by restricting public access

• To allow public access to all objects

• To reduce storage costs

• To enable faster uploads

What is an Access Control List (ACL) used for in AWS S3?

• To enable versioning for objects

• To delete objects after a certain period

• To encrypt objects automatically

• To define read and write permissions at the object level
