Enable Delete Protection for the Firewallβ
To prevent accidental or unauthorized deletion, enable Delete Protection on the AWS Network Firewall.
From Command Lineβ
Run the following command to enable delete protection:
aws network-firewall update-firewall-delete-protection \
--firewall-arn {{firewall-arn}} \
--delete-protection-enabled
Once enabled, delete protection must be explicitly disabled before the firewall can be deleted.
