Question

An organization needs to determine how many employees are accessing the building each day in order to configure the proper access controls. Which of the following control types best meets this requirement?

Options

  • ADetective
  • BPreventive
  • CCorrective
  • DDirective

Explanation

Detective controls identify and record events that have already occurred - counting who enters a building each day is exactly this: observing and measuring activity to inform decisions, which fits the detective category perfectly.

Why the distractors are wrong:

  • B (Preventive) - prevents unauthorized access from happening in the first place (e.g., a locked door or badge reader that blocks entry), not counts it.
  • C (Corrective) - responds after an incident to fix or remediate damage (e.g., revoking access after a breach), not gathering baseline data.
  • D (Directive) - guides behavior through policies or instructions (e.g., "all employees must badge in"), not measuring actual behavior.

Memory tip: Think "Detective = Data collection" - just like a detective gathers evidence about what happened, detective controls gather information about events. If the control answers "what is happening or what happened?", it's detective.
