Configuring DNS Black Hole on Win2003 Server running Plesk

Hi all,

I was wondering if anyone could help me configure DNS to deny access or else based on third party dns black lists.

My server has several websites open for sql injection and Id like to stop it, first by identifying the IP addresses or domains of the ofenders and denying them access to the websites.

I'm new to all this, so if you can give me clear instructions and suggestions, I appreciate it.

:Thanks

Eder

Yes, I've come to that option, however, the offenders of my server are the same all over the internet.
So instead of entering them manually one by one, I'd rather get a list from another source and just update it once in a while.

One problem in doing it the way you suggested is that I do not know how to recognize the offender on the traffic logs.

If anybody can help me with identifying them, I'll go with IP blocking for now, as the situation is an emergency.

Thanks!

port 1433 is (normally) access to sql via tsql-- wouldn't blocking it with a firewall and making sure that the only access is internal solve the problem? You don't need to know all the possible sources (unless I don't understand how you are using it).
If you block it at the firewall pointed to the ISP you end access for all.

Hi Iscarbor.

So far I have done nothing but patch a few websites and clean the infected databases.
Today we applied a patch to one of them and will monitor for the following days to see if it solved the problem.

In the meantime I will look into what you suggested and will post back soon.

Thanks for your help so far.
