I know that access control is a very important think when we want to protect our files and in security in general. Does anyone know what access control system is used by linux?
In addition I just found the Bell-LaPadula model, which I find very interesting as a model, as it has top-secret flags etc. Does anyone know if this model is used anywhere in practice? Or is it just theoretical?
In addition, If I want to have a Linux system to have very strong access control, and I want to use this model, does anyone knows what I have to do?
