In other words: even with standards you'd still be doing it wrong. Standards don't mean security. Standards don't mean quality.
Look at ISO 9000 "Quality Management Sysytems". It's actually made it so that your processes are repeatable and any deviation can be found and fixed. It doesn't mean the management systems are of "quality".
I see "standards" in the context of this thread being used as a buzzword, a panacea that will cure all ailments. It's not. People still have to put things together in a way that
a) it works when plugged in
b) it is safe
c) it is understandable to those who were trained in the way of the technology
It doesn't mean John Doe, the butcher, can design and deploy an IP network at home because it follow standards.
John Doe can probably plug the yellow ethernet cable from the modem to the yellow port in the router, and use the other black cables to plug the black ethernet cables from the devices to the black port in the router. That's all he needs to know. He doesn't need to know IP.
John Doe, the MD can probably plug the yellow, red, white cables from the yellow, red, white ports in his VCR to the yellow, red, white cables in his TV.
That's all John Doe, the butcher and John Doe, the MD need to know about the technology behind these kinds of sorcery.
