Businesses do hire people qualified for the job in general. However they have lots of different jobs with different qualifications needed and so they have lots of different qualifications in play.

I'm not an accountant so if I do something that negatively affects accountants I won't find out - unless what I do shows up in an audit. My company has put things in place so that it is unlikely I would accidentally do something that would show up in an audit (most of them are best practices that every company has). I do have a company credit card, and I can make other purchases on behalf of my company - but if I tried to send my brother in law a million dollars I doubt I could do that (not that I would)

As web engineers what do you have in place so that if someone who competent in a different area does something in the web area and breaks things will will notice and stop them?

I think part of the reason is that management usually know enough about accounting that they know enough to hire the right people, ask the experts in the area the right questions, and ensure someone implements best practices.

If you did it would almost certainly be noticed and you would face consequences. That is why something more complex than just a transfer (very often something very elaborate) is required for fraud.

Then again everyone accepts you need to do things to stop fraud, that the trade offs (things taking more time and effort, not being able to do somethings) from the necessary precautions.
