I have to manage the security of thousands of laptops. Nowadays our laptops have two partitions, C:, hidden to users but accessible and D: where users store documents, images, etc.
Do this separation increase security?
My opinion is that with correct permissions, in Windows, the separation of partitions does not increase security because what is most important are the permissions and the separation of the partitions do nothing.
Can I put everything in C: and mantain the same level of security?
