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:

Metric	Definition	Target	NIST CSF
MTTD	Time from threat occurrence to SOC detection	<15 min	Detect
MTTA	Time from alert to analyst acknowledgment	<5 min	Respond
MTTI	Time from acknowledgment to investigation start	<10 min	Respond
MTTC	Time from investigation to containment	<1 hour	Respond
MTTR	Time from detection to full resolution	<4 hours	Recover
FP Rate	Percentage of false positive alerts	<30%	Detect
TP Rate	Percentage of true positive alerts	>40%	Detect
Coverage	ATT&CK techniques with active detection	>60%	Detect
Dwell Time	Attacker time in network before detection	<24 hours	Detect
Escalation Rate	% of Tier 1 alerts escalated to Tier 2/3	15-25%	Respond

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
| table owner, alerts_resolved, alerts_per_day, avg_triage_min, unique_rule_types

Shift-Based Workload Distribution:

index=notable earliest=-30d
| eval hour = strftime(_time, "%H")
| eval shift = case(
    hour >= 6 AND hour < 14, "Day (06-14)",
    hour >= 14 AND hour < 22, "Swing (14-22)",
    1=1, "Night (22-06)"
  )
| stats count AS alerts, dc(owner) AS analysts by shift
| eval alerts_per_analyst = round(alerts / analysts / 30, 1)
| table shift, alerts, analysts, alerts_per_analyst

Step 4: Track Detection Coverage

ATT&CK Coverage Score:

| inputlookup detection_rules_attack_mapping.csv
| stats dc(technique_id) AS covered_techniques by tactic
| join tactic type=left [
    | inputlookup attack_techniques_total.csv
    | stats dc(technique_id) AS total_techniques by tactic
  ]
| eval coverage_pct = round(covered_techniques / total_techniques * 100, 1)
| sort tactic
| table tactic, covered_techniques, total_techniques, coverage_pct

Data Source Coverage:

| inputlookup expected_data_sources.csv
| join data_source type=left [
    | tstats count where index=* by sourcetype
    | rename sourcetype AS data_source
    | eval status = "Active"
  ]
| eval source_status = if(isnotnull(status), "Collecting", "MISSING")
| stats count by source_status
| table source_status, count

Step 5: Build Executive Reporting Dashboard

Monthly SOC Executive Summary:

--- Incident summary by category
index=notable earliest=-30d status_label="Resolved*"
| stats count by urgency
| eval order = case(urgency="critical", 1, urgency="high", 2, urgency="medium", 3,
                    urgency="low", 4, urgency="informational", 5)
| sort order

--- Month-over-month comparison
index=notable earliest=-60d
| eval period = if(_time > relative_time(now(), "-30d"), "This Month", "Last Month")
| stats count by period, urgency
| chart sum(count) AS incidents by urgency, period

--- Top 5 incident categories
index=notable earliest=-30d status_label="Resolved - True Positive"
| top rule_name limit=5
| table rule_name, count, percent

Security Posture Scorecard:

| makeresults
| eval metrics = mvappend(
    "MTTD: 8.3 min (Target: <15 min) | STATUS: GREEN",
    "MTTR: 3.2 hours (Target: <4 hours) | STATUS: GREEN",
    "FP Rate: 27% (Target: <30%) | STATUS: GREEN",
    "Detection Coverage: 64% (Target: >60%) | STATUS: GREEN",
    "Analyst Utilization: 78% (Target: 60-80%) | STATUS: GREEN",
    "Incident Backlog: 12 (Target: <20) | STATUS: GREEN"
  )
| mvexpand metrics
| table metrics

Step 6: Implement Continuous Improvement Tracking

Track improvement initiatives and their impact:

--- Improvement initiative tracking
| inputlookup soc_improvement_initiatives.csv
| eval status_color = case(
    status="Completed", "green",
    status="In Progress", "yellow",
    status="Planned", "gray"
  )
| table initiative, start_date, target_date, status, metric_impact, baseline, current

Example initiatives:

initiative,start_date,target_date,status,metric_impact,baseline,current
Risk-Based Alerting,2024-01-15,2024-03-15,Completed,Alert Volume,-84%,287/day
Sigma Rule Library,2024-02-01,2024-04-01,In Progress,ATT&CK Coverage,61%,64%
SOAR Phishing Playbook,2024-02-15,2024-03-30,In Progress,Phishing MTTR,45min,18min
Analyst Training Program,2024-01-01,2024-06-30,In Progress,TP Rate,31%,41%

Key Concepts
