Question

Accepted Answer

Web Application Firewall (WAF) protects web applications from attacks by monitoring and filtering HTTP traffic.

WAF acts as a barrier between the web application and the internet, filtering and monitoring incoming traffic to block malicious requests.
It can prevent common attacks like SQL injection, cross-site scripting (XSS), and DDoS attacks.
WAF can be deployed as a hardware appliance, virtual appliance, or cloud-based service.
Use cases include protecting e-commerce websites from credit card fraud, securing online banking applications, and safeguarding sensitive data in healthcare applications.
