Why is DNSSEC important? Because, DNSSEC protects from the following attach, called DNS spoofing.

The CloudFormation templates used in the video are available at https://github.com/widdix/aws-cf-templates
I’ve used the following commands to deploy DNSSEC to
us-east-1. Make sure to modify the stack names and parameters before using the commands.
aws cloudformation deploy --stack-name cloudonautio-key --template-file security/kms-key.yaml --parameter-overrides Service=dnssec-route53 KeySpec=ECC_NIST_P256 KeyUsage=SIGN_VERIFY
When it comes to DNS, I’m using the book DNS and BIND to learn about the technical details.
