The Chief Technical Officer (CTO) has been informed of a potential fraud committed by a
database administrator performing several other job functions within the company. Which of the
following is the BEST method to prevent such activities in the future?

A.
Job rotation

B.
Separation of duties

C.
Mandatory Vacations

D.
Least Privilege

Explanation:
Separation of duties means that users are granted only the permissions they need to do their work
and no more. More so it means that you are employing best practices. The segregation of duties
and separation of environments is a way to reduce the likelihood of misuse of systems or
information. A separation of duties policy is designed to reduce the risk of fraud and to prevent
other losses in an organization.
