Which of the following controls requires separate entities, operating together, to complete a task?

A.
Least privilege

B.
Data hiding

C.
Dual control

D.
Administrative

Explanation:
Dual control requires that two or more entities work together to
complete a task. An example is key recovery. If a key needs to be recovered and it
requires two or more people to authenticate to a system, the act of them coming
together and carrying out these activities is known as dual control. This reduces
the possibility of fraud.
