Web Application Firewall (WAF) and its critical role in protecting web applications .

This presentation introduces the concept of a Web Application Firewall (WAF) and its critical role in protecting web applications from online threats. It explains how WAF works by inspecting HTTP/HTTPS traffic, applying filtering rules, and using positive or negative security models. The presentation details common types of WAF deployments, including cloud-based, on-premises, and hybrid solutions. It highlights key benefits such as protection against SQL injection and cross-site scripting (XSS), regulatory compliance, and performance improvements. A must-have layer in modern web security strategies for businesses and developers.
