UpdateFirewallConfig - Amazon Route 53

UpdateFirewallConfig

Updates the configuration of the firewall behavior provided by DNS Firewall for a single VPC from Amazon Virtual Private Cloud (Amazon VPC).

Request Syntax

{ "FirewallFailOpen": "string", "ResourceId": "string" }

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.

FirewallFailOpen

Determines how Route 53 Resolver handles queries during failures, for example when all traffic that is sent to DNS Firewall fails to receive a reply.

  • By default, fail open is disabled, which means the failure mode is closed. This approach favors security over availability. DNS Firewall blocks queries that it is unable to evaluate properly.

  • If you enable this option, the failure mode is open. This approach favors availability over security. DNS Firewall allows queries to proceed if it is unable to properly evaluate them.

This behavior is only enforced for VPCs that have at least one DNS Firewall rule group association.
