+# Sample Cyber Detection Logic
+
+## Purpose
+
+This document defines sample cyber event-generation logic for Project Phoenix. These rules can be used to create cyber events and send them into the backend ingestion pipeline.
+
+---
+
+## 1. Brute Force Login Detection
+
+Condition:
+If the same IP address or username has 5 or more failed login attempts within 10 minutes.
+
+Generated Event:
+
+{
+  "event_id": "CYB-BF-001",
+  "timestamp": "2026-05-17T10:00:00Z",
+  "event_type": "cyber",
+  "source": "auth-service",
+  "threat_type": "brute_force",
+  "severity": "high",
+  "confidence_score": 0.92
+}
+
+Response Action:
+investigate
+
+---
+
+## 2. Suspicious API Usage Detection
+
+Condition:
+If one IP repeatedly accesses sensitive endpoints or receives many 401, 403, or 429 responses.
+
+Generated Event:
+
+{
+  "event_id": "CYB-API-001",
+  "timestamp": "2026-05-17T10:05:00Z",
+  "event_type": "cyber",
+  "source": "api-gateway",
+  "threat_type": "suspicious_api_usage",
+  "severity": "medium",
+  "confidence_score": 0.85
+}
+
+Response Action:
+monitor_closely
+
+---
+
+## 3. Abnormal Activity Detection
+
+Condition:
+If a user performs unusual behaviour, such as accessing restricted endpoints or too many resources quickly.
+
+Generated Event:
+
+{
+  "event_id": "CYB-ABN-001",
+  "timestamp": "2026-05-17T10:10:00Z",
+  "event_type": "cyber",
+  "source": "activity-monitor",
+  "threat_type": "abnormal_activity",
+  "severity": "medium",
+  "confidence_score": 0.82
+}
+
+Response Action:
+monitor_closely
+
+---
+
+## 4. Malware or Phishing Indicator Detection
+
+Condition:
+If suspicious files, malicious links, or phishing indicators are detected.
+
+Generated Event:
+
+{
+  "event_id": "CYB-MAL-001",
+  "timestamp": "2026-05-17T10:15:00Z",
+  "event_type": "cyber",
+  "source": "content-scanner",
+  "threat_type": "malware",
+  "severity": "critical",
+  "confidence_score": 0.98
+}
+
+Response Action:
+urgent_response
+
+---
+
+## Severity Mapping
+
+low -> monitor  
+medium -> monitor_closely  
+high -> investigate  
+critical -> urgent_response  
+
+---
+
+## Integration Notes
+
+These cyber events can be generated from:
+- login/authentication logs
+- API gateway logs
+- user activity logs
+- suspicious file or content scanning
+- abnormal behaviour detection
+
+The generated events can be sent into the existing backend ingestion pipeline and later displayed through the frontend dashboard.
