# CYB007 — Synthetic Insider Threat Dataset (Sample)

**XpertSystems.ai Synthetic Data Platform · SKU: CYB007-SAMPLE · Version 1.0.0**

This is a **free preview** of the full **CYB007 — Synthetic Insider Threat
Dataset** product. It contains roughly **~10% of the full dataset** at
identical schema, actor-tier distribution, and statistical fingerprint, so
you can evaluate fit before licensing the full product.

| `incident_summary.csv`        | ~500           | ~4,800        | Per-incident aggregate outcomes              |
| `incident_events.csv`         | ~38,687         | ~48,000       | Discrete incident event log                  |

## Dataset Summary

CYB007 simulates end-to-end insider threat incident lifecycles as a **6-phase
state machine** across enterprise org topologies with calibrated UEBA
defender modeling, covering:

- **4 actor threat-type tiers**: negligent_user, malicious_employee,
  privileged_insider, compromised_account — with per-tier stealth weights,
  data access scopes, cover-tracks propensity, and collusion probabilities
- **8 UEBA defender statuses** (graduated maturity ladder): no_ueba,
  dlp_only, siem_only, partial_coverage, pam_integrated, hr_integrated,
  full_coverage, zero_trust_enforced — each with distinct detection_strength
  and alert_suppression characteristics
- **6 lifecycle phases**: reconnaissance, access_escalation, data_staging,
  exfiltration_attempt, cover_tracks, incident_resolution
- **Exfiltration channels**: email, USB, cloud upload, print, screen capture
- **HR-trigger modeling** — disgruntlement signals, performance reviews,
  resignation indicators, and behavioural anomalies that flag IR
- **Collusion modeling** — coordinated multi-actor incidents with weighted
  per-tier collusion probabilities
- **Attribution risk scoring** — recon intensity × stealth weight
- **Sabotage outcomes** — destructive insider actions distinct from
  exfiltration

## Calibrated Benchmark Targets

The full product is calibrated to 12 benchmark validation tests drawn from
authoritative insider threat research (CERT Insider Threat Center, Verizon
DBIR, IBM Cost of Insider Threats, Ponemon Institute, MITRE ATT&CK, NIST
SP 800-53 / SP 800-207, Securonix, Forrester UEBA, Gartner ZTNA,
CrowdStrike, Mandiant M-Trends).

Sample benchmark results:

| Test | Target | Observed | Verdict |
|------|--------|----------|---------|
| exfiltration_success_rate_priv | 0.1460 | 0.1524 | ✓ PASS |
| detection_rate_zero_trust | 0.9100 | 0.9100 | ✓ PASS |
| alert_suppression_rate | 0.0770 | 0.0798 | ✓ PASS |
| data_access_volume_mean_mb | 220.0 | 151.5 | ~ MARGINAL |
| cover_tracks_rate | 0.1800 | 0.1720 | ✓ PASS |
| dwell_time_ratio | 0.2200 | 0.2212 | ✓ PASS |
| stealth_score_privileged | 0.6800 | 0.7047 | ✓ PASS |
| hr_trigger_rate | 0.1600 | 0.1220 | ✓ PASS |
| incident_success_rate | 0.3400 | 0.3500 | ✓ PASS |
| lateral_access_rate | 0.1100 | 0.1092 | ✓ PASS |
| collusion_rate | 0.0850 | 0.0420 | ~ MARGINAL |
| attribution_risk_score | 0.3100 | 0.2746 | ✓ PASS |

*Note: some benchmarks (e.g. privileged_insider exfil success rate,
collusion rate, attribution risk) are conditional on smaller actor-tier
subsets. The full product (4,800 incidents) demonstrates all 12 benchmarks
at Grade A- or better with strong statistical power.*

## Loading the Data

enriched = trajectories.merge(incidents, on=["incident_id", "actor_id"],
                              how="left", suffixes=("", "_summary"))

# 4-class threat-type classification target
y_tier = incidents["threat_type_tier"]
