Question

A company has proprietary data available by using an Amazon CloudFront distribution.

Explanation

WAF IP address set: By creating a WAF IP address set that matches the known IP address ranges of the corporate office, you can explicitly allow only those IPs to access the distribution. Set the default action to Block on the existing web ACL and add a high-priority rule (priority 0) to allow traffic from the corporate IP address set. This configuration will block all traffic by default, except traffic coming from the allowed corporate IP range.
