Aynı saldırıyı devam ettirin, saldırıyı durdurmayın lütfen :) Böylece gerçek bir deneme yapmış oluruz.

Yukarıdaki loglara göre direk "/" şeklinde anasayfaya değil farklı sorgularla saldırıyorsunuz. Bende ? işareti bulunan sorguları blockladım buyrun atak anında durduruldu tüm istekler durduruldu:

Tespit edip durdurma sürecinde evet maalesef site kapalı kalabilir. Siz aynı saldırıyı değiştirmeden devam ettirdiğiniz sürece blocklanmaya devam eder.

Dediğim gibi "/" şeklinde ana dizine saldırsaydınız koruma bile eklemeyecektirm. Şu an ?samdams gibi sorgular olduğu için koruma eklemek zorundayım.

kullandığın kural bütün siteye uygulanamyormu?
