CompTIA Security+ (SY0-501) — Question 191

Having adequate lighting on the outside of a building is an example of which of the following security controls?

Answer options

Correct answer: A

Explanation

Adequate lighting acts as a deterrent by discouraging potential intruders due to the increased likelihood of being seen. The other options do not fit as well; compensating controls are alternative measures that are used when primary controls are not effective, detective controls are meant to identify incidents after they occur, and preventative controls aim to stop incidents before they happen, which lighting alone does not achieve.
