Route53 Resolver Security

Route53 Resolver DNS Firewall Custom Template

Configuration templates to deploy an AWS Route53 Resolver Firewall and related settings including firewall rule groups, custom domain lists, and VPC associations. This configuration can be used to block DNS requests for malicious or unwanted domains.

The following resources are available for configuration:

  • Firewall Rule Groups – define a set of rules that allow, block or alert on DNS requests that match the associated domain lists. AWS managed URL domain lists are available for Malware and Botnet C&C URLs, or custom domain lists can be defined
  • Domain List – a set of domain specifications that you use in a DNS Firewall rule, inside a rule group. Each domain listed must be alphanumerical (or can optionally start with *)
  • VPC Association – Associated the newly created Firewall Rule Group with a VPC in the AWS account
