Free ISC2 CC Certified in Cybersecurity Actual Exam Questions - Question 5 Discussion
Which of the following is a detection control?
A, because detection controls are about noticing threats, not just stopping them.
I agree with choosing A since smoke sensors actively identify problems instead of just blocking or controlling entry like B, C, and D do. Detection means spotting an issue early, which fits smoke sensors perfectly. A
I’d rule out C and D because firewalls and bollards are mainly about blocking or restricting, not alerting. So A seems like the clear detection tool here, but anyone else see it differently?
It’s A because smoke sensors notify you of danger, which is exactly detection.
B imo, turnstiles are more about preventing unauthorized access, so they’re more of a preventive control. Detection controls should alert you to an issue, which turnstiles don’t really do.
Makes sense to pick A since smoke sensors alert you when something’s wrong, which is exactly what detection controls do. The others mostly stop or restrict stuff rather than detect it. A
D imo, since bollards are mostly physical barriers designed to prevent vehicle access, they don't really detect anything. Firewalls (C) monitor traffic but mainly act as a barrier, and turnstiles (B) control entry points but don’t detect threats. Smoke sensors (A) actually pick up signs of danger early on, making them true detection controls. So, A fits the detection category best here.
Makes sense to go with A here. The others—turnstiles, firewalls, and bollards—are more about prevention or blocking access, not really detecting problems. Smoke sensors fit the detection role perfectly since they alert but don’t physically stop anything.
Maybe D is a good pick too if you think about it differently. Bollards don't just prevent vehicles from passing; they can sometimes be equipped with sensors to detect collisions or attempts to breach a perimeter. That said, the question probably focuses on the primary function, which is prevention. Still, it’s worth noting they do have some detection features in advanced setups, unlike turnstiles or firewalls which mostly block access or traffic. So, while smoke sensors (A) are pure detection, bollards might have a detection aspect but not as their main role.
A vs C? Smoke sensors detect hazards directly, firewalls also detect threats but mainly in cyberspace.
C/D? Firewalls (C) definitely monitor traffic and spot threats, so they count as detection controls. Bollards (D) are just physical blockers, so that’s more prevention than detection.
C Firewalls can detect unusual traffic or potential intrusions, so they have a detection role, not just prevention like physical barriers. It’s not as obvious as smoke sensors but still fits detection control.
D imo, bollards are physical barriers to prevent vehicle access, so that’s more of a preventive control, not detection. Smoke sensors directly detect hazards, making A the clearer detection choice here.
C/A? Firewalls can detect suspicious traffic, but smoke sensors purely detect hazards.
It’s A for me too. Just to add, firewalls (C) mainly block or filter traffic, so they’re more preventive than detection. Turnstiles and bollards are physical controls to stop or limit access, not to sense or alert. Smoke sensors actually pick up signs of trouble early, so they fit detection control perfectly.
B and D seem more about restricting access, not catching events after they happen.
Guessing A here. Turnstiles (B) and bollards (D) are more about prevention or physical barriers, not really about detecting issues. Firewalls (C) mostly stop attacks before they happen instead of detecting them once they're in. Smoke sensors actively detect something happening, like a fire, so they fit detection control best.
Yeah, smoke sensors fit detection best here. I’d go with A.
Maybe A. Firewalls mainly block threats, so they’re more preventative. Smoke sensors specifically spot problems early, which is what detection controls do. The others are mostly physical barriers or access controls.
Isn't firewalls more about prevention than just detection? That rules out C for me.
