Hi Chris,

It's good practice to keep an up-to-date list of file hashes for any system you deploy. Before you deploy the system and after each upgrade you verify the hashes and take new ones if necessary.

I acctually finished writing a script in python which does this on Linux and Win systems. If any are interested I'll happily post it to the list (160 lines in length) with the standard "USE AT YOUR OWN RISK" disclaimer.

Currently I'm using the script to keep a closer eye on my testing machines (The Win boxes) and I've deployed it on my laptop (the Linux machine).

Again, this isn't hard at *all* and it is something you can EASILY re-program for your shop and put in a scheduled task. Python also gives you some flexability in reporting etc etc etc.

Dear List

Is there anything that performs binary integrity checks for Windows OS such as rpm does for Redhat or apt does for Debian?

I want something that will check Windows binaries against a trusted source - MS site, install cd, etc so that I can determine integrity baselines of current production systems before deploying an integrity checking application.

I would have thought that this would be something Microsoft would provide, but have not seen anything.

Thanks for any input

Chris
