Correct answer & explanation
Preventive: Firewall
The correct matches are: Preventive controls prevent incidents (e.g., firewall), Detective controls identify incidents (e.g., IDS), Corrective controls fix issues (e.g., backup/restore), and Deterrent controls discourage attacks (e.g., warning signs). Options E and F are common confusions where definitions are swapped.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Preventive: Firewall
Why this is correct
Preventive controls aim to stop incidents before they occur; a firewall blocks unauthorized access.
Detective: Intrusion Detection System
Why this is correct
Detective controls identify ongoing or past incidents; an IDS monitors network traffic for suspicious activity.
Corrective: Backup and restore
Why this is correct
Corrective controls remedy issues after an incident; backup and restore recovers lost data.
Deterrent: Security warning signs
Why this is correct
Deterrent controls discourage attackers; warning signs signal consequences and monitoring.
Preventive: Backup and restore
Why it's wrong here
Incorrect — backup and restore is a corrective control, not preventive.
Detective: Firewall
Why it's wrong here
Incorrect — a firewall is a preventive control, not detective.
