Segregation of Duties

A method of working whereby tasks are apportioned between different members of staff in order to reduce the scope for error and fraud. For example, users who create data are not permitted to authorise processing; Systems Development staff are not allowed to be involved with live operations.

This approach will not eliminate collusion between members of staff in different areas, but is a deterrent. In addition, the segregation of duties provides a safeguard to your staff and contractors against the possibility of unintentional damage through accident or incompetence - 'what they are not able to do (on the system) they cannot be blamed for'.
