Building SOC Metrics and KPI Tracking

When to Use

Use this skill when:

• SOC leadership needs data-driven visibility into operational performance
• Continuous improvement programs require baseline measurements and trend tracking
• Executive reporting demands quantified security posture and ROI metrics
• Staffing decisions need objective workload and capacity data
• Compliance audits require documented SOC performance evidence

Do not use metrics as punitive measures against analysts — metrics should drive process improvement, not individual performance management.

Prerequisites

• SIEM with 90+ days of incident and alert disposition data
• Incident ticketing system (ServiceNow, Jira) with timestamp data for incident lifecycle
• Analyst shift schedules and staffing data
• ATT&CK Navigator for detection coverage tracking
• Dashboard platform (Splunk, Grafana, or Power BI)

Workflow

Step 1: Define Core SOC Metrics Framework

Establish the key metrics aligned to NIST CSF functions:

Step 2: Implement MTTD/MTTR Measurement

Mean Time to Detect (MTTD):

index=notable earliest=-30d status_label="Resolved*"
| eval mttd_seconds = _time - orig_time
| where mttd_seconds > 0 AND mttd_seconds < 86400  --- Exclude data quality issues
| stats avg(mttd_seconds) AS avg_mttd,
        median(mttd_seconds) AS med_mttd,
        perc90(mttd_seconds) AS p90_mttd,
        perc95(mttd_seconds) AS p95_mttd
  by urgency
| eval avg_mttd_min = round(avg_mttd / 60, 1)
| eval med_mttd_min = round(med_mttd / 60, 1)
| eval p90_mttd_min = round(p90_mttd / 60, 1)
| table urgency, avg_mttd_min, med_mttd_min, p90_mttd_min

Mean Time to Respond (MTTR):

index=notable earliest=-30d status_label="Resolved*"
| eval mttr_seconds = status_end - _time
| where mttr_seconds > 0 AND mttr_seconds < 604800  --- <7 days
| stats avg(mttr_seconds) AS avg_mttr,
        median(mttr_seconds) AS med_mttr,
        perc90(mttr_seconds) AS p90_mttr
  by urgency
| eval avg_mttr_hours = round(avg_mttr / 3600, 1)
| eval med_mttr_hours = round(med_mttr / 3600, 1)
| eval p90_mttr_hours = round(p90_mttr / 3600, 1)
| table urgency, avg_mttr_hours, med_mttr_hours, p90_mttr_hours

MTTD/MTTR Trend Over Time:

index=notable earliest=-90d status_label="Resolved*"
| eval mttd_min = (_time - orig_time) / 60
| eval mttr_hours = (status_end - _time) / 3600
| bin _time span=1w
| stats avg(mttd_min) AS avg_mttd_min, avg(mttr_hours) AS avg_mttr_hours,
        count AS incidents by _time
| table _time, incidents, avg_mttd_min, avg_mttr_hours

Step 3: Measure Alert Quality and Analyst Productivity

Alert Disposition Analysis:

index=notable earliest=-30d
| stats count AS total,
        sum(eval(if(status_label="Resolved - True Positive", 1, 0))) AS tp,
        sum(eval(if(status_label="Resolved - False Positive", 1, 0))) AS fp,
        sum(eval(if(status_label="Resolved - Benign", 1, 0))) AS benign,
        sum(eval(if(status_label="New" OR status_label="In Progress", 1, 0))) AS pending
| eval tp_rate = round(tp / total * 100, 1)
| eval fp_rate = round(fp / total * 100, 1)
| eval signal_noise = round(tp / (fp + 0.01), 2)
| table total, tp, fp, benign, pending, tp_rate, fp_rate, signal_noise

Analyst Productivity Metrics:

index=notable earliest=-30d status_label="Resolved*"
| stats count AS alerts_resolved,
        avg(eval((status_end - status_transition_time) / 60)) AS avg_triage_min,
        dc(rule_name) AS unique_rule_types
  by owner
| eval alerts_per_day = round(alerts_resolved / 30, 1)
| sort - alerts_resolved
