Machines: Yes this was the 80's (sorry I didn't point that out my mistake) and things have changed. However to that point if you have your golden machine operator turning out good work (and he is only 1 of 2 on a particular line) and it's not easy to hire a replacement, let alone a good replacement, you tend to get a bit lax.
Security: I am primarily a business guy (who does some light programming and knows Unix since the 80's) so I hire others to do work for me. I am just thinking that for the people that I have hired in the past how would anyone know if any of this is happening (other than code audits) and what is the mechanism to make sure the right thing happens even if you know what the right thing is? It's kind of a version of the advice "make backups but make sure that you test your backups as well".
