Windows IIS日志文件分析程序
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，訪問者查看了哪些內容等等。通過定期檢查這些日志文件，網站管理員可以檢測到服務器或站點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URL地址進行攻擊的分析并不多，下面是一個VB Script程序，保存為VBS程序后可以在服務器上運行，用于分析和檢測IIS日志里針對某個URL地址進行攻擊的IP地址。
'代碼開始
targeturl = "/archives/2761.html" '受攻擊網站的URL地址。
logfilepath = "C:\LogFiles\W3SVC\ex110813.log" '受攻擊網站的日志路徑。
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 "結束."
Sub writelog(errmes)
ipfilename = "blockip.txt"
Set logfile = fileobj.opentextfile(ipfilename, 8, True)
logfile.writeline errmes
logfile.Close
Set logfile = Nothing
End Sub
'代碼結束
IIS日志
分析出來的IP如果出現異常，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導入，即可批量屏蔽攻擊者的IP地址。
