but this is the security issue dating back to before the 80s
... when
they decided they could no longer guarantee single point of
security ...
in part because of insider threats ... they added multiple
independent
sources as a countermeasure. the crooks responded with
collusion ... so
you started to see countermeasures to collusion appearing in
the early 80s.
the advent of the internet, sort of refocused attention to
outsider
attacks ... even tho the statistics continue to hold that
the major
source of fraud is still insiders ... including thru the
whole internet
era. the possibility of outsiders may have helped insiders
obfuscate
true source of many insider vulnerabilities.
the issue with auditing to prove no possible vulnerability
for a single
point ... leading to the extremes of having to prove a
negative ... can
possibly be interpreted within the context of attempting to
preserve the
current audit paradigm.
independent operation/sources/entities have been used for a
variety of
different purposes. however, my claim has been then auditing
has been
used to look for inconsistencies. this has worked better in
situations
where there was independent physical books from independent
sources
(even in the same corporation).
As IT technology has evolved ... my assertion is a complete
set of
(consistent) corporate books can be generated from a single
IT
source/operation. The IRS example is having multiple
independent sources
of the same information (so that you can have independent
sources to
check for inconsistencies).
The fusion scenarios tend to be having multiple independent
sources of
at least some different data ... so the aggregation is more
than the
individual parts (as opposed to the same data to
corroborate).
