# 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):**
```spl
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):**
```spl
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:**
```spl
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:**
```spl
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:**
```spl
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:**
```spl
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:**
```spl
| 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
```

### Step 5: Build Executive Reporting Dashboard

**Monthly SOC Executive Summary:**
```spl
--- 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
```

### Step 6: Implement Continuous Improvement Tracking

Track improvement initiatives and their impact:

```spl
--- 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:
```csv
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

| Term | Definition |
|------|-----------|
| **MTTD** | Mean Time to Detect — average time from threat occurrence to SOC alert generation |
| **MTTR** | Mean Time to Respond — average time from detection to incident resolution |
| **MTTA** | Mean Time to Acknowledge — average time from alert generation to analyst assignment |
| **Signal-to-Noise Ratio** | Ratio of true positive alerts to total alerts — higher is better |
| **Dwell Time** | Duration an attacker remains undetected in the environment — key indicator of detection effectiveness |
| **Analyst Utilization** | Percentage of analyst time spent on productive investigation vs. overhead tasks |

## Tools & Systems

- **Splunk Dashboard Studio**: Advanced visualization framework for building interactive SOC metric dashboards
- **Grafana**: Open-source analytics and visualization platform supporting multiple data sources
- **Power BI**: Microsoft business intelligence tool for executive-level reporting and trend analysis
- **ATT&CK Navigator**: MITRE tool for visualizing detection coverage as layered heatmaps
- **ServiceNow Performance Analytics**: ITSM analytics module for tracking incident lifecycle metrics

## Common Scenarios

- **Quarterly Business Review**: Present MTTD/MTTR trends, detection coverage growth, and alert quality improvements
- **Staffing Justification**: Use workload metrics to justify additional analyst headcount or shift adjustments
- **Tool ROI Assessment**: Compare alert quality and response times before and after new tool deployment
- **Compliance Evidence**: Provide documented SOC performance metrics for ISO 27001 or SOC 2 audits
- **Vendor Comparison**: Benchmark SOC metrics against industry peers using surveys (SANS, Ponemon)
