Windows Server具有事件日志記錄的功能，其IIS日志文件里記錄了包括下列信息：誰訪問了您的站點(diǎn)，訪問者查看了哪些內(nèi)容等等。通過定期檢查這些日志文件，網(wǎng)站管理員可以檢測到服務(wù)器或站點(diǎn)的哪些方面易受攻擊或存在其他安全隱患。
不過，目前的日志分析工具并不是很完善，有些功能并不具備，特別是針對某個(gè)URL地址進(jìn)行攻擊的分析并不多，下面是一個(gè)VB Script程序，保存為VBS程序后可以在服務(wù)器上運(yùn)行，用于分析和檢測IIS日志里針對某個(gè)URL地址進(jìn)行攻擊的IP地址。

- targeturl = "/archives/2761.html" '受攻擊網(wǎng)站的URL地址。
- logfilepath = "C:\LogFiles\W3SVC\ex110813.log" '受攻擊網(wǎng)站的日志路徑。
- On Error Resume Next
- Set fileobj = CreateObject("scripting.filesystemobject")
- Set fileobj2 = CreateObject("scripting.filesystemobject")
- Set myfile = fileobj2.opentextfile(logfilepath, 1, False)
- Do While myfile.atendofstream <> True
- myline = myfile.readline()
- myline2 = Split(myline, " ")
- newip = myline2(9)
- myurl = myline2(5)
- If targeturl = myurl Then
- writelog newip
- End If
- Loop
- myfile.Close
- Set fileobj2 = Nothing
- Msgbox "結(jié)束."
- Sub writelog(errmes)
- ipfilename = "blockip.txt"
- Set logfile = fileobj.opentextfile(ipfilename, 8, True)
- logfile.writeline errmes
- logfile.Close
- Set logfile = Nothing
- End Sub
分析出來的IP如果出現(xiàn)異常，可以通過程序，將其批量添加到IIS的屏蔽IP列表里，下面是網(wǎng)上找到的一段VBScript代碼，將其改名為vbs后，把上面那段程序的IP導(dǎo)入，即可批量屏蔽攻擊者的IP地址。
