A Web Application Firewall (WAF) is a security solution that monitors, filters, and blocks HTTP traffic to and from a web application. Unlike traditional firewalls that operate at the network level, WAFs understand application-layer protocols and can detect and prevent attacks that target web application vulnerabilities.
What a WAF Protects Against
SQL Injection attacks that attempt to manipulate database queries. Cross-Site Scripting (XSS) that injects malicious scripts into web pages. DDoS attacks that overwhelm your server with traffic. Brute force login attempts. Malicious bot traffic and automated scraping. File inclusion and path traversal attacks.
How WAFs Work
WAFs use a combination of signature-based detection for known attack patterns, behavioral analysis for anomalous traffic, and reputation-based filtering using threat intelligence databases. Modern WAFs also leverage machine learning to identify new attack patterns and reduce false positives.
