Which metric is used by SOC management to measure the average "Dwell Time"—the duration between...

MTTD (Mean Time to Detect) is one of the most critical Key Performance Indicators (KPIs) for evaluating SOC effectiveness.

Defining Dwell Time: MTTD measures the gap between the Incident Start Time (when the attacker first gained access) and the Detection Time (when the alert was raised). A high MTTD indicates that attackers are staying hidden in the network for long periods.

SOC Maturity: A mature SOC aims to drive MTTD as low as possible using automation (XSOAR) and proactive threat hunting (XQL) to find stealthy intrusions before they can reach the "Exfiltration" stage.

Difference from MTTA: MTTA (Mean Time to Acknowledge) only measures how fast a human analyst clicks "Assign to me" after the alert has already been generated.
