Has anyone had experience with or is aware of any products that hash the OS kernel? This would be used, ideally, for watching for system compromises, auditing, change management, etc. I am looking for products, either open source or commercial, that have this capability. If such a product does not exist, does anyone have any ideas on how this could be done? Also, if this is not currently available, does anyone know of any academic research that has been performed in this arena?
Thanks in advance.
