Object labeling (or labeled security) looks simple and straight forward way, but it's not.
(1) Object labeling has a assumption that labels are always properly defined and maintained. This can not be easily achieved. (2) Also, assigning a label is something like inventing and assigning a *new* name (label name) to objects which can cause flaws.
I'm not saying labeled security or SELinux is wrong. I just wanted to remind that the important part is the "process" not the "result". :-)
