Audit Controls: The common definition of an audit is a valuation of a person, association, system, procedure, enterprise, product or project. The word most generally refers to audits in accounting, internal auditing, and government auditing, however alike concepts too exist in the project management, water management, quality management, and energy conservation.
This simple perception is that controls can be stated in terms of three main categories.
Protective or Preventative - these controls serve to proactively define and probably enforce the adequate behaviors.
Detective - Detective controls are frequently thought of as "Audit Controls" although we do not require restricting them. Any control which performs a monitoring activity can possibly be stated as a Detective Control.
Reactive - Reactive or corrective controls usually work in response to the detective control, responding in such a manner as to alert or else accurate an unacceptable situation.
