Auditing through the computer

Division of responsibility or duties.
Control over development and maintenance of software
Control over operators.
Control over data access and program access.
Control over editing of data.
Storage control.
Hardware control.

13. EDP APPLICATION CONTROL
For the smooth working of EDP system, besides the general EDP controls, there should certain special EDP application controls. The important EDP application controls are 1) Control over input 2) Control over processing 3) Output control
