5. A full security check of all software, and related items to software, every time that there is a upgrade, is almost

impossible to run/do in the usual time allowed by IT entities prior to the new software being installed.

This is a simple benefit ratio, spend XXX number of hours checking out/testing the new software, vs. spending only X number of hours.

As IT systems get more and more interrelated, more complex, it gets more and more difficult to fully assess the revised or new software.

Most IT people know this already, having come up against company strict guidelines on how much money and time they can spend on testing new/revised software, vs. "Install the new software already!" I've always hated this, but I can understand why. One could literally spend six months to fully test something, vs. actually spending a week testing it. It's just how much depth you want to go in testing, checking out the new/revised software.
