- WAF (Web Application Firewall) is used in conjunction with the CloudFront and ALB services to inspect and block/allow web requests based on user-configurable conditions.
- HTTPS and HTTP requests are supported with this service.
- WAF's strength is in detecting malicious activity based on pattern-matching inputs for attacks such as SQL injections, XSS, etc.
- WAF supports inspection of requests [received through both IPv6 and IPv4](https://aws.amazon.com/about-aws/whats-new/2016/10/ipv6-support-for-cloudfront-waf-and-s3-transfer-acceleration/).
