Which of the following security controls might force an operator into collusion with personnel assigned organizationally within a different function in order to gain access to unauthorized data? 

Answer options:

A. Limiting the local access of operations personnel
B. Job rotation of operations personnel
C. Management monitoring of audit logs
D. Enforcing regular password changes

A

The questions specifically said:"within a different function" which eliminate Job Rotation as a choice. Management monitoring of audit logs is a detective control and it would not prevent collusion. Changing passwords regularly would not prevent such attack. This question validates if you understand the concept of separation of duties and least privilege.By having operators that have only the minimum access level they need and only what they need to do their duties within a company, the operations personnel would be force to use collusion to defeat those security mechanism.
