Starting today AWS WAF (Web Application Firewall) is available on the Application Load Balancer (ALB). You can now use AWS WAF directly on Application Load Balancers (both internal and external) in a VPC, to protect your websites and web services. With this launch customers can now use AWS WAF on both Amazon CloudFront and Application Load Balancer.

AWS WAF is a web application firewall service that lets you monitor web requests and protect your web applications from malicious requests. Use AWS WAF to block or allow requests based on conditions that you specify, such as the IP addresses. You can also use AWS WAF preconfigured protections to block common attacks like SQL injection or cross-site scripting.

An Application Load Balancer is a load balancing option that operates at the application layer and allows you to define routing rules based on content across multiple services or containers running on one or more Amazon Elastic Compute Cloud (Amazon EC2) instances.
