不过，目前的日志分析工具并不是很完善，有些功能并不具备，特别是针对某个URL地址进行攻击的分析并不多，下面是一个VB Script程序，保存为VBS程序后可以在服务器上运行，用于分析和检测IIS日志里针对某个URL地址进行攻击的IP地址。
targeturl = "/archives/2761.html" '受攻击网站的URL地址。
logfilepath = "C:\LogFiles\W3SVC\ex110813.log" '受攻击网站的日志路径。
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 "结束."
Sub writelog(errmes)
ipfilename = "blockip.txt"
Set logfile = fileobj.opentextfile(ipfilename, 8, True)
logfile.writeline errmes
logfile.Close
Set logfile = Nothing
End Sub

分析出来的IP如果出现异常，可以通过程序，将其批量添加到IIS的屏蔽IP列表里，下面是网上找到的一段VBScript代码，将其改名为vbs后，把上面那段程序的IP导入，即可批量屏蔽攻击者的IP地址。
