You run an ad-supported photo sharing website using S3 to serve photos to visitors of your site. At some point
you find out that other sites have been linking to the photos on your site, causing loss to your business. What
is an effective method to mitigate this?
Remove public read access and use signed URLs with expiry dates.
Use CloudFront distributions for static content.
Block the IPs of the offending websites in Security Groups.
Store photos on an EBS volume of the web server.
