Answer: A
Since small stand-alone business computer environments
normally lack basic controls such as access control software
and a strict segregation of duties, strong compensating

of computer usage must be relied upon. This takes the form
of monitoring office activity, reviewing key control
reports, and sampling employee work to ensure it is
appropriate and authorized.
