昨晚突然出現大量的Exception,發現是某個IP攻擊網站,所以就直接使用IIS擋IP方式阻擋該IP的攻擊,但是設定之後,發現Exception還是一直出來。但是束手無策....直到一個多小時後才停止攻擊。
事後翻出IIS Log看結果
發現IIS擋IP有發揮作用(status:403) 但是會有漏網之魚(status:302-其實status是500)
檢查 "23:10:46" 一秒內受到 36 次攻擊 但是漏掉了 8 個 -> 失敗率約兩成
結論:
1. 對於阻斷攻擊,可能還需要程式上做處理,例如 begin_request 時檢查
2. Log Parser 真是看 log 最佳工具....
