- Basic configuration for AWS WAF, solely focused on dealing with L7 DDoS attacks. This is by no means a comprehensive WAF configuration, but it's super effective against HTTP floods.

Exactly what I needed, brilliant video and covers a lot of important points, thank you.
Out of curiosity, say if an IP address was blocked, is that just for the 5 minute window, or does that go into a blocked ip list which is editable? The latter is very appealing to me.
The IP remain limited until it stops sending traffic for a while. The list is not editable, but you can use cli or api to list the offending IPs - docs.aws.amazon.com/waf/latest/developerguide/listing-managed-ips.html
@@the-aws-ninja Great thanks are you going to do a video on setting up CloudFront for all that additional noise you spoke of here? Would love to see it.
I don't know computer knowledge,,,,, thanks lot,,,❤❤
thank you so much
hi thanks for this video, question is this aws shield / waf apply in all ec2 servers?
You apply waf to CloudFront, alb, api gw, and a few other services. Shield is applicable to CloudFront and alb, as well as elastic IP
Do I need to point the aws instance/domain somewhere after creating the rules ? I mean I have a single web apache server in aws ec2, this rules will apply automatic without pointing to the instance or I need to point this rules to the instace/domain ?
I need to attach the web acl to a CloudFront distribution or an ALB, and they should point to your instance.
If it's just a single server, CloudFront is cheaper and better in your case.
Hello i have an ec2 instance. How do i link the instance to the waf?
Either put an ALB on top of it, or better use CloudFront. Attach WAF to either ALB or CloudFront
hello! It works in Elastic Beanstalk apps?
You can certainly use WAF on top of ALB
How would solve the following risk with POST based rate limiting: A single IP can easily cause a denial of service to other users by POSTing beyond this limit.
Absolutely. You should always keep multiple layers of rate based rules - IP based for non Distributed attempts, and non IP based for other attacks.
You can also create, for the POST scenario, 2 rate based rules - one set as low as 100 requests per IP, scoped down to only POST requests, and another rule, set at a higher threshold, to count ALL POST requests.
Thank you for this question!
