You can use CloudFront's geo restriction feature to restrict access to your content based on the geographic location of your viewers. This feature allows you to either allow or block access to your content from specific countries.
Here are the steps to turn on CloudFront geo restriction for your distribution:
1. Open the CloudFront console.
2. Choose the distribution that you want to apply geo restriction to.
3. Choose the Geographic Restrictions tab.
4. Choose Edit.
5. To allow access to countries, for Restriction type choose **Allow List**. To block access from certain countries, choose Block List.
6. For Countries, select the countries that you want to allow or block. Then, choose Add.
7. Choose Save Changes.
This way, you can ensure that only users who access your website through the United States are authorized in CloudFront. Is there anything else you would like to know?
