You are designing a website for a company that streams anime videos.
You serve this content through CloudFront.
The company has implemented a section for premium subscribers.
This section contains more videos than the free section.
You want to ensure that only premium subscribers can access this premium section.

A. B. C. D.Correct Answer: D.
Option A is incorrect.
Bucket policies are mainly used with resources in AWS.
They are not intended to restrict content to application users.

This option only encrypts the communication between users and CloudFront.
It does not restrict access to files.

With a signed URL, you only restrict access to one file.
If you implement this, the application would have to generate a new pre-signed URL for every file in the premium section and give this new link to the user.

Once your application allows your user to see this section, it will give a cookie to the user.
Then CloudFront will use this cookie to access S3 restricted content.

Explanation:
When designing a website that offers premium content, it is important to ensure that only users who have paid for access to that content can view it. One way to achieve this is by using CloudFront origin with signed URLs.
Signed URLs are URLs that have an expiration time and an encrypted signature attached to them. The signature is created using a secret key that is only known to the website's servers. When a user clicks on a signed URL, CloudFront checks the signature to ensure that the URL is valid and has not expired. If the signature is valid and the URL has not expired, CloudFront will grant access to the requested content.
By using CloudFront origin with signed URLs, the website can provide access to premium content only to users who have paid for it. When a user pays for access to the premium section, the website's servers generate a signed URL that grants access to that user for a specified period of time. This signed URL is then sent to the user, who can use it to access the premium content.
Bucket policies (option A) are used to define access controls for Amazon S3 buckets. While they can be used to restrict access to content, they are not as flexible as CloudFront signed URLs and are not designed to handle time-limited access.
Requiring HTTPS for communication between users and CloudFront (option B) is a good security practice, but it does not provide a way to restrict access to premium content.
Using CloudFront origin with signed cookies (option D) is another way to restrict access to content, but it requires more configuration than using signed URLs. Signed cookies are more useful for scenarios where access controls need to be applied to specific parts of a website rather than specific content.
Therefore, the best option for achieving the desired outcome is option C: Using CloudFront origin with signed URLs.
