Which metric would best indicate the efficiency of an organization's ability to detect security incidents?
Scope of impact
Mean time to remediate
Alert volume
Mean time to detect
Mean time to detect (MTTD) measures how quickly an organization can identify that a security incident has occurred. A lower MTTD indicates a more efficient detection capability. Mean time to remediate (MTTR) measures the time taken to resolve an incident, while alert volume and scope of impact are related but do not directly measure detection efficiency.
