Answer 1

AWS Web Application Firewall (AWS WAF) can be deployed on Amazon CloudFront, Amazon Elastic Compute Cloud (Amazon EC2), Amazon API Gateway, and Application Load Balancer to protect web applications from common web exploits and attacks.

Step-by-step explanation:

AWS Web Application Firewall (AWS WAF) can be deployed on the following services:

• Amazon CloudFront
• Amazon Elastic Compute Cloud (Amazon EC2)
• Amazon API Gateway
• Application Load Balancer

AWS WAF is a web application firewall that helps protect your web applications from common web exploits that could affect application availability, compromise security, or consume excessive resources. It works by inspecting web requests and filtering out malicious traffic.

For example, if you have a web application running on Amazon EC2 instances and fronted by an Application Load Balancer, you can deploy AWS WAF on the Application Load Balancer to protect your application from attacks like SQL injection or cross-site scripting.
