Thanks. I hadn't used the Lockdown tool before, I did all my security manually so I 
knew exactly what was chaning on the server.

I'm excited to see my logs after today.

Thanks again, j

Possible options:

a) Don't have websites that listen on IP addresses alone. Set your websites
to listen on IP Address + Host Header. Since these worms attack by using
HTTP 1.0 requests (IP address only), your website logs will never get these
logged.

and/or

b) Use URLScan

Subject: Filtering DDOS, Scans and Hacks


I'm finally sick of it - logs full of requests used to, well, hack my
system, searching for directories and permissions that I've long locked down
and patched.

**** Example Requests *****
/cgi-bin/..%5c..%5c..%5c..%5c..%5c..%5cwinnt/system32/cmd.exe, /c+dir+c:\,
/winnt/system32/cmd.exe, /c+dir+c:\,
/d/winnt/system32/cmd.exe, /c+dir+c:\,
 /iisadmpwd/..%2f..%2f..%2f..%2f..%2f..%2fwinnt/system32/cmd.exe,
/c+dir+c:\,
*****

Anyway, as I was preparing to run a WebTrends, I was scanning the logs for a
new site we put up and all it is are these types of requests.  Essentially,
we'll always probably have to deal with these things as they are too many
machines out there that are infected with administrators that don't
know/don't care/don't know what to do about it.

Anyway (again) I'm looking for ways to stop these requests before they ever
hit my logs. I'd like to stop them at the firewall, but that hasn't happened
yet. Becuase I need to stop them at the IIS Server, I'm thinking the only
way to do this is to install an ISAPI filter that will just ignore these
requests.

Does anyone out there have a filter like this, or another method, that keeps
my logs a little cleaner?
