iis security:
Hi to all,
I have an Internet Server with W2003 and recently we were hacked. I will appreciate if somebody can suggest me a site for novices like me where in a simple language I can find out how to secure my server. Our provider doesn't gives us any support on this matter (he should) and as a friend told me, our server has more security holes than a Swiss cheese. I'm just a programmer so I have a very basic knowledge on server administration. Best regards,
Hi Jason,
Thanks for you reply. As you say my friend has given me a lot of support and it looks that many problems have been corrected to the date, but anyway after all the problems that I had with the server, I have the purpose of at least learning some basics on server security. It's a must for me. I can tell you that I noticed that we had a security problem because I started finding lots of new folders and/or files in the IIS folder, which I erased many times and again were created in the server. Now we have a folder with no name which I haven't been able to remove. As you suggest, about patches, we are up to date with the latest ones, windows update is active in our server and I'm permanently checking and installing new ones when I log into the server and receive alerts of new patches ready to install. Now I'm also using Microsoft Baseline Security Analyzer and tools like TcpView, ProcExp and other ones that my friend installed in the server. I will start reading from the links that you returned me in your answer, and for sure I will be back with new questions as I learn about the matter. Once again, thank you very much for your time.

Hi Jorge,
There are plenty of resources out there - try Technet for instance http://www.microsoft.com/technet/ also www.iisanswers.com www.iisfaq.com www.securityfocus.com You'll probably find MBSA extremely useful, too: http://www.microsoft.com/technet/security/tools/mbsahome.mspx I'd suggest also, since your friend claims to know what he's talking about, that you draft him in to actually give you some details on his 'more holes than swiss cheese' assertion, because without some detail, that's really no good to you. A major part of security is just common sense - making sure your passwords are strong, that anonymous FTP is disabled or tightened, that patches are applied, services you don't use are turned off and so on.

Sounds like if you were finding new, hard to erase folders in the wwwroot
then you were probably sitting there with anonymous access enabled to FTP (or a very weak password), which is a pretty common attack on freshly set-up boxes. It's not something that MBSA would pick up, and it's not something you'd have fixed by a patch - it's a misconfiguration. I assume you've closed it now? -- Jason Brown Microsoft GTSC, IIS This posting is provided "AS IS" with no warranties, and confers no rights.

Now we >have a folder with no name which I haven't been able to remove. Likely you opened FTP for anonymous write (in IIS6 that's blocked by default). See: Cannot Delete Files or Folders with Extended Characters: http://support.microsoft.com/default.aspx?scid=kb;en-us;131702 How to Remove Files with Reserved Names in Windows: http://support.microsoft.com/default.aspx?scid=kb;en-us;120716 You Cannot Delete a File or a Folder http://support.microsoft.com/?id=320081 As for the security, remember that security is only as good as your entire operation. If I call you and ask for the admin password and an IP to access the system and you provide it, no patches or updates will ever keep me from breaking in. Security is a process, not an event.

> Security is a process, not an event. I'm aware of that Jeff, that's why I'm here making questions to a group that for sure counts with many experts from who I can learn a lot, thank you very much for the links :) Best regards,
