How can you better understand the types of security controls than putting them into an example? Home security in this case.

Deterrent controls: a sticker on the front window saying that the house is linked to a security center.  Or a dog house. 

Preventive controls: locks on the access doors and windows. And a big dog. PS: defense in depth is critical.

Detective controls: security cameras calling up the monitoring center and/or the owner smartphone. Or a dog who never sleeps and who barks really loud. PS: detective controls imply that an attack has begun.

Corrective controls: a loud, indoor siren and a system that blinks the house lights when an intrusion is detected. Or a dog that can bring more bad dogs to save the day. PS: corrective controls react to an attack

Compensating controls: motion sensors on the outside of the building and on all the floors, on top of the ones installed on the ground floor. Or a second dog. PS: compensating controls are added after identifying deficiencies in existing controls
