Hi Chris,

Thank you for posting this question since I have the exact same one. Let me tell you that I've created an AWS support ticket and they replied saying that their engineering team is working on it, but there is no ETA at the moment.

Here's the response I got from AWS:

Good afternoon,

Thanks for contacting AWS Support. It's Dennis from networking team in Sydney. My pleasure to assist you with this case today.

I see that you would like to enable logging for your WAF using CloudFormation. Currently the logging configuration can be enabled and configured with Kinesis Firehose using the awscli commands and via the console. However, there is no way to do it using the CloudFormation scripts.

Our internal teams are striving to achieve logging configuration update through CloudFormation, but with no ETA to provide.

If you have more questions or concerns, please do not hesitate to update the case and our team will be happy to help you.

Best regards,

Dennis L.
