What is Web Application Firewall in Cybersecurity?
A security control that filters and monitors HTTP/HTTPS traffic between a web application and the internet. WAFs protect against web-specific attacks like SQL injection, cross-site scripting, and request forgery. They operate at Layer 7 and can be deployed as hardware, software, or cloud services.
Why Web Application Firewall Matters for Your Cybersecurity Career
WAFs protect web applications that cybersecurity teams cannot patch immediately. Security engineers configure WAF rules and handle false positives that block legitimate traffic. Penetration testers routinely test WAF bypass techniques during assessments. Cloud WAF services (AWS WAF, Cloudflare, Akamai) make WAF knowledge valuable for cloud security roles.
