Why each option

Security cameras function as detective controls because their primary purpose is to observe and record events, allowing for post-incident analysis and identification of unauthorized activities. While they can also deter, their core role is detection.

Adeterrent control

Deterrent controls discourage attacks before they happen (e.g., warning signs). While cameras can have a deterrent effect, their primary function is detection.

Bdetective controlCorrect

Security cameras primarily act as detective controls. Their main function is to monitor activities, record events, and provide evidence for investigation after a security incident has occurred. While their presence might deter some malicious actors, their inherent operational capability is to detect and document.

Cpreventive control

Preventive controls stop an attack from happening (e.g., door locks, firewalls). Security cameras do not prevent an attack from occurring.

Dcorrective control

Corrective controls are used to fix issues after an incident (e.g., backups, patching). Security cameras do not fix or recover from an incident; they provide information about it.
