The default security mechanism that's available with the operating system uses file permissions.
This is what we refer to as discretionary access control.
We call it discretionary because basic object permissions are subject to the whims of the object owner.
This simply means the owner of a file or process can grant access to that object to any other user on
the system.
As such if users refuse to adhere to strict security practices the safety of the operating system can
be seriously affected.
SC Linux removes this problem by adding an extra layer of security to the operating system.
This is called Mandatory Access Control because when activated it becomes compulsory and can not be
ignored or bypassed by anyone on the system.
Not even vert.
