Web Application Firewall (WAF) Testing: Bypass Techniques and Effectiveness — 日本企業向けガイド

Web Application Firewalls add a protective layer between attackers and applications, but they are not a substitute for secure code. WAF testing evaluates: detection coverage (does it block the attacks relevant to your application?), bypass techniques (encoding, fragmentation, protocol-level evasion, payload mutation), false positive rates, and whether the WAF creates a false sense of security that discourages proper application-layer fixes.
