WAFs can be implemented by a network security appliance deployed on-premise or as a cloud-based service. The WAF can also be configured to log all activity for forensic analysis and compliance purposes. The WAF would be configured to monitor incoming traffic to the web application, and if it detects any suspicious activity that matches the defined rules, it would block or redirect the traffic to a safe destination.

A WAF can be deployed in front of the web application to protect against common web application attacks. For example, a hospital may have a web application that allows patients to access their medical records online. One potential use case for a WAF is in the healthcare industry, where web applications are often used to manage patient data. The WAF is designed to operate at the application layer and uses a set of rules to identify and block malicious traffic before it reaches the application.

A web application firewall (WAF) is a security platform that helps protect web applications from a range of attacks by monitoring and filtering incoming and outgoing HTTP/HTTPS traffic between a web application and the internet.
