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URL地址進(jìn)行攻擊的分析并不多，下面是一個VB Script程序，保存為VBS程序后可以在服務(wù)器上運行，用于分析和檢測IIS日志里針對某個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

End Sub
'代碼結(jié)束
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。
