Hello, I'm interested in writing a Kernel Extension that allows me to block write access to files. Essentially I want to be able to block ALL users, including ROOT from being able to write to files from within applications such as MS WORD, or any of the web browsers. I'd like to be able to do this in kernel level meaning that its not just a permission but its more like impossble. Can someone give me some pointers on this? What should I be using? Has anyone done this before? I am aware that there will be inconsistancies and errors introduced but I'm willing to tolerate / fix / learn about the issues involved. --Matthew K.
