系統日誌中的陌生IP登入信息

文章frankfu » 週四 2月 26, 2015 11:27 am

你好,我的郵件伺服器不斷出現如下日誌,高峰期可以達到幾千條。導致伺服器資源耗盡當機,
請問是什麽原因導致?如何應對較好?謝謝。

Re: 系統日誌中的陌生IP登入信息

文章peter » 週三 3月 04, 2015 10:23 am

您好

這要看目前您使用我們設備的型號版本為何

如使用MS32系列
可參考下面版本說明
http://www.sharetech.com.tw/web_tw/PDF/ ... V1.5.2.pdf
其中的項目八、 IP 封鎖相關修正 IP 封鎖相關修正
• [垃圾郵件管理>SMTP 漏洞與 IP 封鎖]IP 封鎖功能增加[使用者認證異常情形封鎖]。

如使用MS64系列
功能項目
郵件稽核及防護 > 郵件防火牆
使用者認證異常情形

自動偵測及封鎖:使用者認證異常的來源IP。
使用者認證方式:包含使用 SMTP(SASL) / POP3 / IMAP / SMTPS / POP3S / IMAPS 協定登入認證。


上述功能啟動之後
就可以主動的封鎖異常嘗試帳密登入的情形
