Correct answer & explanation
✓
Restoring data from backup after a ransomware attack
Corrective controls are designed to remediate or reverse the effects of an incident after it has occurred. Restoring data from backup after a ransomware attack directly addresses the damage by recovering lost or encrypted data, making it a classic corrective control. In contrast, preventive controls (like firewalls) block incidents before they happen, and detective controls (like IDS alerts or log monitoring) identify incidents after they occur but do not fix the damage.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is confusing detective controls (which identify incidents) with corrective controls (which fix the damage), leading candidates to pick IDS alerts or log monitoring as corrective actions when they only provide visibility, not remediation.
Detailed technical explanation
How to think about this question
Corrective controls often involve recovery procedures such as restoring from a verified, offline backup (e.g., using VSS snapshots or tape backups) to ensure data integrity after a ransomware attack. In real-world scenarios, organizations must test backup restoration processes regularly (e.g., via DR drills) because ransomware can encrypt backup repositories if they are not air-gapped or immutable. The NIST SP 800-53 framework categorizes such controls under the 'IR' (Incident Response) and 'CP' (Contingency Planning) families, emphasizing the need for validated recovery points.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the CRISC exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
