Project rules¶

Rule - Mandatory Access Control¶

As these are mandatory access control policies only what is explicitly required should be authorized. Meaning, you should not allow everything (or a large area) and deny some sub areas.

Rule - Do not break a program¶

A profile should not break a normal usage of the confined software. this can be complex as simply running the program for your own use case is not always exhaustive of the program features and required permissions.

Rule - Do not confine everything¶

Some programs should not be confined by a MAC policy.

Rule - Distribution and devices agnostic¶

A profile should be compatible with all distributions, software, and devices in the Linux world. You cannot deny access to resources you do not use on your devices or for your use case.
