work of each other?

Dual control

C.

D.
Segregation control

Explanation:
“In the concept of two-man control, two operators review and approve the work of each other. The
purpose of two-man control is to provide accountability and to minimize fraud in highly sensitive or
high-risk transactions. The concept of dual control means that both operators are needed to
complete a sensitive task.” Pg. 303 Krutz: The CISSP Prep Guide: Gold Edition.
