There are a couple of (free) ways to go about this, particularly on Windows systems...

For system assessment, I'd recommend:
nmap - http://www.insecure.org
ATK - http://www.computec.ch/projekte/atk/

If you know what you're assessing against, Perl can be used to implement WMI as well as make other calls to the system 
in order to obtain the necessary information for your assessment...and even update the system to bring it in compliance.

Perl can also be used to implement free monitoring/hIDS.  For example, if you set your audit policy appropriately, use 
something like wmievt.pl (http://patriot.net/~carvdawg/perl.html) to send Event Log entries off of the system as they 
are generated.  From the same site, you can use FSW.pl to watch for file system changes.
