vigilance

Vigilance is devoted attentiveness or watchfulness. Security guards and test proctors alike need to practice vigilance.

Vigilance comes from the Latin word for "wakefulness," vigilantia, and in a medical setting vigilance is still sometimes used to mean "insomnia." A prison guard might be required to maintain vigilance the whole time she's working, always being alert and watchful.
