Web Application Firewall

AWS WAF is a web application firewall that helps protect our web applications from common web exploits that could affect application availability, compromise security, or consume excessive resources. AWS WAF helps protect web applications from attacks by allowing us to configure rules that allow, block, or monitor (count) web requests based on conditions that we define. These conditions include IP addresses, HTTP headers, HTTP body, URI strings, SQL injection, and cross-site scripting. New rules can be deployed within minutes, letting us respond quickly to changing traffic patterns.
