Under CSF 2.0, restoring assets and operations affected by a cybersecurity incident is the outcome of which Function?
ARESPOND
BPROTECT
CRECOVER
DDETECT
Answer & Solution
Correct answer: C. RECOVER
1. RECOVER is defined as: "Assets and operations affected by a cybersecurity incident are restored."
2. The expansion adds the purpose: RECOVER "supports the timely restoration of normal operations to reduce the effects of cybersecurity incidents and enable appropriate communication during recovery efforts".
3. RESPOND is the near neighbour and the one most often confused with it. RESPOND is "Actions regarding a detected cybersecurity incident are taken", and it "supports the ability to contain the effects" of the incident.
4. So the split is containment versus restoration: RESPOND stops the bleeding, RECOVER puts things back.
5. PROTECT applies safeguards before anything happens, and DETECT finds the incident in the first place.
