Which of the following is the best example of need-to-know?

A.
An operator does not know more about the system than the minimum required to do the job.

B.
An operator cannot generate and verify transactions alone.

C.
The operators’ duties are frequently rotated.

D.
Two operators are required to work together to perform a task.

Explanation:
The correct answer is “An operator does not know more about the system than the minimum
required to do the job”. Need-to-know means the operators are working in an environment that
limits their knowledge of the system, applications, or data to the minimum elements that they
require to perform their job. * Answer “Two operators are required to work together to perform a
task” is dual-control * “The operators’ duties are frequently rotated” is job rotation * answer “An
operator cannot generate and verify transactions alone” is separation of duties.
