Hi,

I am new to IIS security and am wondering a couple of things:
1) We log the events of our iis machine, how can i tell if someone is trying to break into our server from the log files?
2) Is there any where i can find advice on security polices and implementation of iis?

You can also check out what hacker behaviour looks like with a program like Nessus, as it is a popular hacker tool. Or implement and IDS like Snort. Gfi Languard network security scanner is also a valuable assessment threat tool. Nessus is more up2date and regular audits should be run often on your network. An IDS like snort can alert you in real-time when an attack may be occuring.  The links above did not mention the IIS lockdown tool... http://www.microsoft.com/windows2000/downloads/recommended/iislockdown/default.asp This can help alot... please test.
