Description

Amazon Route 53 Resolver DNS Firewall (DNS Firewall) enables you to defend against DNS-level threats. With DNS Firewall, you can protect against data exfiltration attempts by defining domain name allowlists that allow resources within your Amazon Virtual Private Cloud (VPC) to make outbound DNS requests only for the sites your organization trusts.
