Separation of duties (SoD) is the concept of having more than one person required to complete a task. It is alternatively called segregation of duties or, in the political realm, separation of powers. Segregation of duties helps reduce the potential damage from the actions of one person. IS or end-user department should be organized in a way to achieve adequate separation of duties.
