# 🔒 SHHH Hypercore Log Monitor - Implementation Plan

## Executive Summary

This plan outlines the creation of a Python application that monitors our hypercore log to ensure no secrets are leaked in BZZZ messages, based on the SHHH module's secrets detection framework.

## Project Overview

### Objective
Create a real-time monitoring system that:
- Monitors hypercore log entries for secret patterns
- Detects potential secrets in BZZZ P2P messages before they propagate
- Quarantines suspicious entries and triggers automatic remediation
- Provides audit trails and security dashboard for compliance

### Architecture Integration
- **Hypercore Log**: Source of truth for all CHORUS Services events
- **BZZZ Network**: P2P messaging layer that could inadvertently transmit secrets
- **SHHH Module**: Existing secrets detection framework and patterns
- **Monitoring App**: New Python application bridging these systems

## Technical Requirements

### 1. Hypercore Log Integration
```python
# Real-time log monitoring
- Stream hypercore entries as they're written
- Parse BZZZ message payloads for secret patterns
- Filter for message types that could contain secrets
- Handle log rotation and recovery scenarios
```

### 2. Secret Detection Engine
Based on SHHH's `patterns.yaml` framework:
```yaml
patterns:
  AWS_ACCESS_KEY:
    regex: "AKIA[0-9A-Z]{16}"
    severity: "HIGH"
    confidence: 0.95
    active: true
  GITHUB_TOKEN:
    regex: "ghp_[0-9A-Za-z]{36}"
    severity: "HIGH"
    confidence: 0.92
    active: true
  PRIVATE_KEY:
    regex: "-----BEGIN [A-Z ]*PRIVATE KEY-----"
    severity: "CRITICAL"
    confidence: 0.98
    active: true
```

### 3. Quarantine & Response System
- **Immediate**: Block message propagation in BZZZ network
- **Log**: Store quarantined entries in PostgreSQL
- **Alert**: Notify security team via webhooks
- **Revoke**: Trigger automatic secret revocation APIs

## Implementation Architecture

    def stream_entries(self) -> Iterator[LogEntry]:
        """Stream new hypercore entries in real-time"""
        # Tail-like functionality with inotify
        # Parse hypercore binary format
        # Yield structured LogEntry objects
        
    def parse_bzzz_message(self, entry: LogEntry) -> Optional[BzzzMessage]:
        """Extract BZZZ message payload from hypercore entry"""
        # Decode BZZZ message format

    def scan_message(self, message: BzzzMessage) -> List[SecretMatch]:
        """Scan BZZZ message for secret patterns"""
        matches = []
        for pattern_name, pattern in self.patterns.items():
            if pattern["active"]:
                matches.extend(self.apply_regex(message, pattern))
        return matches
        
    def redact_secret(self, text: str, match: SecretMatch) -> str:
        """Redact detected secret while preserving context"""
        # Replace secret with asterisks, keep first/last chars

        """Store quarantined message and block propagation"""
        # Insert into quarantine table
        # Generate alert payload
        # Trigger BZZZ network block
        
    def send_alert(self, severity: str, secret_type: str, redacted_content: str):
        """Send webhook alerts for detected secrets"""

    def install_message_hook(self):
        """Install pre-send hook in BZZZ network layer"""
        # Intercept messages before P2P transmission
        # Scan with SecretDetector
        # Block or allow message propagation
        
    def block_message(self, message_id: str, reason: str):
        """Prevent message from propagating in P2P network"""
        # Mark message as blocked in BZZZ
        # Log blocking reason

            AccessKeyId=access_key_id,
            Status='Inactive'
        )
        
    async def revoke_github_token(self, token: str):
        """Revoke GitHub personal access token"""
        # Use GitHub's token scanning API
        # Or organization webhook for automatic revocation
        
    async def revoke_slack_token(self, token: str):
        """Revoke Slack bot/user token"""
        # Use Slack Admin API
        # Invalidate token and rotate if possible
```

## Security Considerations

### 1. Secure Secret Storage
- **Never store actual secrets** in quarantine database
- Use **cryptographic hashes** for audit trails
- **Redact sensitive content** while preserving detection context
- Implement **secure deletion** for expired quarantine entries

### 2. Access Control
- **Role-based access** to dashboard (security admin, reviewer, read-only)
- **Audit logging** for all administrative actions
- **OAuth integration** with existing identity provider
- **API key authentication** for automated systems

### 3. Network Security
- **TLS encryption** for all API communication
- **VPN/private network** access to monitoring systems
- **Rate limiting** to prevent API abuse
- **IP allowlisting** for critical endpoints

## Deployment Architecture

      - HYPERCORE_LOG_PATH=/hypercore/current.log
    networks:
      - shhh_network
      - tengig # For dashboard access
```

## Performance Requirements

### Latency Targets
- **Log Processing**: <50ms per hypercore entry
- **Secret Detection**: <10ms per BZZZ message
- **Alert Generation**: <100ms for critical secrets
- **Dashboard Response**: <200ms for UI queries

### Throughput Targets
- **Message Scanning**: 1000 messages/second
- **Concurrent Users**: 10+ dashboard users
- **Alert Volume**: 100+ alerts/hour during peak
- **Database Queries**: <5ms average response time

## Monitoring & Observability

### Metrics Collection
```python
# Prometheus metrics
messages_scanned_total = Counter('shhh_messages_scanned_total')
secrets_detected_total = Counter('shhh_secrets_detected_total', ['secret_type', 'severity'])
detection_latency = Histogram('shhh_detection_latency_seconds')
quarantine_size = Gauge('shhh_quarantine_entries_total')
```

### Health Checks
- **Hypercore connectivity**: Verify log file access
- **Database health**: Connection pool status
- **BZZZ integration**: P2P network connectivity
- **Alert system**: Webhook endpoint validation

### Logging Strategy
```python
# Structured logging with correlation IDs
{
  "timestamp": "2025-08-02T13:45:00Z",
  "level": "WARNING",
  "event": "secret_detected",
  "correlation_id": "req_123",
  "secret_type": "AWS_ACCESS_KEY",
  "severity": "HIGH",
  "hypercore_position": 58321,
  "bzzz_message_id": "msg_abc123",
  "redacted_content": "AKIA****XYZ found in agent message"
}
```

## Testing Strategy

### Unit Tests
- **Regex pattern validation**: Test against known secret formats
- **Message parsing**: Verify hypercore and BZZZ format handling
- **Quarantine logic**: Test storage and retrieval functions
- **Alert generation**: Mock webhook endpoint testing

### Integration Tests
- **End-to-end workflow**: Log → Detection → Quarantine → Alert
- **Database operations**: PostgreSQL CRUD operations
- **BZZZ integration**: Message interception and blocking
- **API endpoints**: FastAPI route testing

### Security Tests
- **Input validation**: SQL injection, XSS prevention
- **Access control**: Role-based permission testing
- **Data protection**: Verify secret redaction and hashing
- **Performance**: Load testing with high message volume
