WAF: Web Application Firewall in Cybersecurity
Rhymes with 'laugh'.
WAF stands for Web Application Firewall. A WAF inspects HTTP/HTTPS traffic between users and web applications to block attacks like SQL injection, cross-site scripting, and request forgery. It applies rule sets that filter malicious requests before they reach the application server.
How WAF Is Used in Cybersecurity
Security engineers configure WAF rules to protect public-facing web applications from OWASP Top 10 attacks. SOC analysts review WAF logs to detect application-layer attack campaigns and credential stuffing attempts. Penetration testers probe WAF configurations to identify bypass techniques and recommend rule improvements.
