Web Application Firewall (WAF) Testing: Bypass Techniques and Effectiveness cho Doanh nghiệp Việt Nam

WAFs provide an additional defence layer, but determined attackers bypass them regularly. How to test WAF effectiveness. Guidance for VN market.

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.
