The control environment is the set of standards, processes, and structures that provide the basis for carrying out internal control across the organization. The control environment is most effective when the controls perform as intended, meaning that they achieve their objectives, mitigate the risks, and comply with the policies and regulations. The other options are desirable attributes of the controls, but they do not necessarily indicate the effectiveness of the control environment. References = Risk and Information Systems Control Study Manual, Chapter 2: IT Risk Assessment, Section 2.3: IT Control Assessment, page 69.
