Why this module exists. “Is our SOC effective?” CISOs need a measurable answer. Common metrics — alert volume, ticket count — measure activity, not effectiveness. The metrics that matter are MTTD (mean time to detect), MTTR (mean time to respond), false-positive rate, and ATT&CK technique coverage.
Why this module exists. “Is our SOC effective?” CISOs need a measurable answer. Common metrics — alert volume, ticket count — measure activity, not effectiveness. The metrics that matter are MTTD (mean time to detect), MTTR (mean time to respond), false-positive rate, and ATT&CK technique coverage. Each has a target; each has specific operational levers.
The four metrics that matter
| Metric | Definition | Mature target |
|---|---|---|
| MTTD | Mean time from compromise to detection | < 1 hour for high-fidelity, < 24h overall |
| MTTR | Mean time from detection to containment | < 30 min for P1 alerts, < 4 hours for P2 |
| FP Rate | % of alerts that turn out benign | < 30% |
| Coverage | % of MITRE ATT&CK techniques with detections | > 60% with high-confidence rules |
Industry baselines (Mandiant M-Trends, IBM Cost of Breach reports): MTTD averages 9-25 days. Mature SOCs are at hours-to-1-day. The gap is mostly tooling + automation, not staffing.
