Your assertion that directly associating
the capabilities with the binary cannot
be analysed is demonstrably incorrect,
reference Common Criteria validation
reports CCEVS-VR-02-0019 and CCEVS-VR-02-0020.
The first system I took through evaluation
(that is, independent 3rd party analysis) stored
security attributes in a file while the second
and third systems attached the attributes
directly (XFS). The 1st evaluation required
5 years, the 2nd 1 year. It is possible that
I just got a lot smarter with age, but I
ascribe a significant amount of the improvement
to the direct association of the attributes
to the file.
