Anti-Defacement Products...

Hi Firewall Wiz's.... 
I was thinking about defacement the other day and how to help automate a
response to this type of activity.  I understand that host based security
and network based security is the key, but what about response.  I am
looking for a product that could be used to make sure the page being
displayed was the real page.  Thoughts of encyting the page/code to get a
hash and storing it somewhere inside the enterprise, periodically the
webserver re-calcing the hash on the page stored locally and running a check
against a the stored copy secured in box on the inside.  I would also
envision the automatic posting of the original source back to the webserver
and alerts bieng generated to the security officer if the two hashes did not
match.  Does anyone know of any product that does something similar?  I was
hoping not to have to build this from scratch, but perhaps it will be my
little project.  Any thoughts about this project or software that might
already do this for me would be greatly appreciated...

Thanks
