# CYB007 — Synthetic Insider Threat Dataset (Sample) (TsFile)

Apache TsFile version of [`xpertsystems/cyb007-sample`](https://huggingface.co/datasets/xpertsystems/cyb007-sample).

## Overview

**CYB007 — Synthetic Insider Threat Dataset (Sample)** — 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.

- **Tables:** `incident_events`, `incident_summary`, `insider_trajectories`, `org_topology`
- **Rows:** 71,927 across 4 TsFile table(s).
  - `incident_events`: 38,687 rows — Time is the source `timestep` simulation step counter, stored as milliseconds (1 step = 1 ms).
  - `incident_summary`: 500 rows — Time is synthetic row index over the stable source order (0 … N-1); the source table has no per-row clock.
  - `insider_trajectories`: 32,500 rows — Time is the source `timestep` simulation step counter, stored as milliseconds (1 step = 1 ms).
  - `org_topology`: 240 rows — Time is synthetic row index over the stable source order (0 … N-1); the source table has no per-row clock.

## Schema (TsFile structure)

### `incident_events.tsfile`

- **Time** (INT64, milliseconds) — the source `timestep` simulation step counter, stored as milliseconds (1 step = 1 ms).
- **TAG**: `incident_id` — device dimension(s); query one device with `WHERE incident_id=...`.
- **FIELD** (5): `actor_id` (string), `event_type` (string), `target_department_id` (string), `dlp_system_id` (string), `colluding_actor_id` (string)

### `incident_summary.tsfile`

- **Time** (INT64, milliseconds) — synthetic row index over the stable source order (0 … N-1); the source table has no per-row clock.
- **TAG**: `incident_id` — device dimension(s); query one device with `WHERE incident_id=...`.
- **FIELD** (27): `actor_id` (string), `actor_threat_type` (string), `target_environment_type` (string), `incident_type` (string), `total_data_accessed_mb` (double), `exfiltration_attempts_total` (int64), `exfiltration_successes` (int64), `exfiltration_success_rate` (double), `detection_rate` (double), `exfiltration_volume_total_mb` (double), `avg_data_access_velocity` (double), `max_privilege_escalation_depth` (int64), `incident_duration_steps` (int64), `lateral_access_count` (int64), `dlp_blind_spots_identified` (int64), `cover_tracks_events` (int64), `hr_case_triggers_caused` (int64), `incident_success_flag` (int64), `attribution_risk_score` (double), `stealth_score` (double), `actor_efficiency_score` (double), `sabotage_events_executed` (int64), `colluding_actor_count` (int64), `coordinated_incident_flag` (int64), `cover_tracks_effectiveness` (double), `organisational_impact_score` (double), `exfiltration_roi_score` (double)

### `insider_trajectories.tsfile`

- **Time** (INT64, milliseconds) — the source `timestep` simulation step counter, stored as milliseconds (1 step = 1 ms).
- **TAG**: `incident_id` — device dimension(s); query one device with `WHERE incident_id=...`.
- **FIELD** (11): `actor_id` (string), `incident_phase` (string), `data_access_volume_mb` (double), `privilege_event_count` (int64), `communication_anomaly_score` (double), `dlp_confidence_score` (double), `detection_outcome` (string), `exfiltration_volume_mb_cumulative` (double), `behavioural_risk_score` (double), `target_data_sensitivity_tier` (string), `actor_threat_type` (string)

### `org_topology.tsfile`

- **Time** (INT64, milliseconds) — synthetic row index over the stable source order (0 … N-1); the source table has no per-row clock.
- **TAG**: `department_id` — device dimension(s); query one device with `WHERE department_id=...`.
- **FIELD** (9): `dlp_system_id` (string), `department_type` (string), `data_sensitivity_tier` (string), `dlp_coverage` (double), `ueba_deployment_status` (string), `privileged_role_density` (double), `alert_threshold` (double), `hr_integration_status` (int64), `pam_coverage` (int64)

## Conversion notes

- Each CSV of the sample is converted into its own TsFile table (4 tables), so no table is merged with another and no column is dropped.
- Event/telemetry tables use the source simulation clock as Time (INT64 milliseconds): `timestep` step counters and millisecond offsets are stored as-is, minute-based columns are multiplied by 60,000, and ISO/UTC strings are parsed to epoch milliseconds.
- Static inventory/topology/summary tables have no per-row clock; their Time is a synthetic row index (0..N-1) over the stable source order.
- Low-cardinality dimensions of each table (campaign/incident/asset/session ids, phases, labels) are declared as TAG columns; query one simulation with e.g. `WHERE campaign_id='...'`.

## Usage

Install the Apache TsFile Python SDK (`pip install tsfile`) and read a converted file:

```python
from pathlib import Path
from tsfile import TsFileReader

path = Path("incident_events.tsfile")
with TsFileReader(str(path)) as reader:
    schemas = reader.get_all_table_schemas()
    print("tables:", list(schemas))
    table_name = next(iter(schemas))
    table = schemas[table_name]
    columns = [column.get_column_name() for column in table.get_columns()]
    print("columns:", columns)
    field_names = [
        column.get_column_name()
        for column in table.get_columns()
        if column.get_column_name() not in {"Time", "time"}
    ]
    if field_names:
        with reader.query_table(table_name, field_names[:3], batch_size=1024) as result:
            batch = result.read_arrow_batch()
            if batch is not None:
                print(batch.to_pandas().head())
```
