+# WitFoo Precinct6 Cybersecurity Dataset (114M)
+
+## Overview
+
+A large-scale, labeled cybersecurity dataset derived from production Security Operations Center (SOC) data processed by [WitFoo Precinct](https://www.witfoo.com/) version 6.x. This dataset contains **114 million sanitized security events** (signal logs) and **provenance graphs** (10,442 incident graphs with 23,362 nodes and 32,732,650 edges) from real enterprise network monitoring across 5 organizations.
+
+**Available in two sizes:**
+- [`witfoo/precinct6-cybersecurity`](https://huggingface.co/datasets/witfoo/precinct6-cybersecurity) — 2M signals (smaller, faster to load)
+- [`witfoo/precinct6-cybersecurity-100m`](https://huggingface.co/datasets/witfoo/precinct6-cybersecurity-100m) — **114M signals (this dataset)**
+
+**Generate your own:** WitFoo Precinct 6.x customers can create datasets from their own data using the open-source pipeline: [`witfoo/dataset-from-precinct6`](https://github.com/witfoo/dataset-from-precinct6)
+
+This dataset is designed to support research in:
+- **Provenance graph-based intrusion detection** (KnowHow, NodLink, and similar systems)
+- **AI-driven cyber defense simulation** (CybORG and MARL-based defense policy training)
+- **Security alert classification** (malicious vs. suspicious vs. benign event labeling)
+- **Attack lifecycle analysis** using MITRE ATT&CK framework mappings
+- **Detection rule evaluation** using WitFoo's 261 lead detection rules
+
+## Quick Start
+
+```python
+from datasets import load_dataset
+
+# Load flat signal logs (114M rows across 58 Parquet shards)
+signals = load_dataset("witfoo/precinct6-cybersecurity-100m", "signals", split="train")
+
+# Find malicious events (from confirmed incidents)
+malicious = signals.filter(lambda x: x["label_binary"] == "malicious")
+
+# Find suspicious events (matched detection rules)
+suspicious = signals.filter(lambda x: x["label_binary"] == "suspicious")
+
+# Query by product/vendor
+cisco_events = signals.filter(lambda x: x["vendor_name"] == "Cisco")
+
+# Load provenance graph
+nodes = load_dataset("witfoo/precinct6-cybersecurity-100m", "graph_nodes", split="train")
+edges = load_dataset("witfoo/precinct6-cybersecurity-100m", "graph_edges", split="train")
+
+# Load full incident graphs
+incidents = load_dataset("witfoo/precinct6-cybersecurity-100m", "incidents", split="train")
+```

+
+## Labeling Methodology
+
+**Three-tier labels** derived from two sources:
+
+- **`malicious`** (125,780): Events embedded as leads inside confirmed incidents. Extracted directly from incident lead objects with suspicion scores, modus operandi, and MITRE mappings.
+- **`suspicious`** (622,700): Events matching WitFoo's 261 lead detection rules (e.g., "ASA Deny", "Windows Failed Login", "CrowdStrike Detection") but not in confirmed incidents.
+- **`benign`** (113,326,050): Events not matching any detection rules and not in any incident.
+
+The `matched_rules` column shows which detection rules matched. The `set_roles` column shows WitFoo classification roles (Exploiting Host, C2 Server, Staging Target, etc.).
+
+## Lead Detection Rules
+
+261 rules included in `reference/lead_rules_catalog.json`. Examples:
+
+| Rule | Criteria | Roles |
+|------|----------|-------|
+| Blocked Action | Any firewall block | Exploiting Host → Exploiting Target |
+| ASA Deny | cisco_asa + deny | Exploiting Host → Exploiting Target |
+| Windows Failed Login | Event ID 4625 | Exploiting Target → Exploiting Host |
+| CrowdStrike Detection | CrowdStrike stream | Exploiting Target → Exploiting Host |
+| AWS VPC Reject | VPC flow + REJECT | Exploiting Host → Exploiting Target |
+| Authentication Failure | auth_failure type | Exploiting Host → Exploiting Target |
+| Audit log cleared | Event ID 1102 | Exploiting Target → Exploiting Host |
+
+## Sanitization
+
+All customer-identifying information removed through a 4-layer iterative pipeline:
+
+1. **Structured field sanitization + Aho-Corasick sweep** (~166,000 patterns) with product identifier protection
+2. **Format-specific message parsing** (8 parsers: Cisco ASA, Windows XML, WinLogBeat, CloudTrail, PAN, VMware, DNS, generic)
+3. **ML/NER residual detection** (Presidio + BERT NER)
+4. **Claude AI contextual review**
+
+Final PII registry: **~302,000 unique mappings** (IPs, hostnames, usernames, orgs, credentials, SIDs, emails, ARNs, etc.)
+
+## Graph Data
+
+| Component | Count |
+|-----------|-------|
+| Nodes | 23,362 |
+| Edges | 32,732,650 |
+| Incidents | 10,442 (Data Theft: 10,441, Phishing: 1) |
+
+## Limitations
+
+- **Label imbalance**: 99.77% benign reflects production SOC reality. Sampling strategies needed for balanced training.
+- **Temporal scope**: July–August 2024
+- **Sanitization**: ~302,000 PII registry entries used for consistent replacement across all records
+- **Shared incidents**: Same 10,442 incidents appear in both 2M and 114M datasets
+- **Sanitization trade-offs**: Some log message detail reduced by PII replacement
