Cloud-based WAF solutions can control the perimeter sprawl with a flexible deployment model that covers applications and services deployed on-premises, on cloud-based IaaS and PaaS environments, and in hybrid environments.

A WAF analyzes the headers, query strings, and body of HTTP requests (e.g., GET requests, POST requests, PUT requests, and DELETE requests) searching for malicious requests, suspicious patterns, and known threats. When a match is found, the firewall can block the request and alert security teams.

AWS WAF helps you protect against common web exploits and bots that can affect availability, compromise security, or consume excessive resources.

By functioning at the application layer of the OSI model, a WAF provides targeted protection against application-specific attacks without affecting legitimate traffic flow. It scrutinizes the content and context of web traffic using a set of rules or policies.
