AI-Powered Detection

Machine Learning Models

• Crypto Asset Baseline: Learns normal certificate patterns
• Anomaly Detection: Identifies unusual crypto configurations
• Threat Intelligence: Correlates with known weak implementations
• Predictive Analytics: Forecasts certificate lifecycle events

Automated Response

• SmartResponse: Automated containment actions
• Case Management: Automatic case creation and assignment
• Threat Hunting: Proactive search for related indicators
• Compliance Reporting: Automated regulatory compliance

Integration Methods

Method 1: System Monitor Collection

Direct log file monitoring by LogRhythm System Monitor

# Configure scanner for file output
./certscanner -mode local -outputformat tychon \
  -output /var/log/tychon/scan.json

# LogRhythm monitors /var/log/tychon/*.json
# Log Source Type: Custom TYCHON Scanner

Method 2: Syslog Forwarding

Real-time syslog forwarding to LogRhythm

# Scanner outputs to syslog
./certscanner -host targets.txt -outputformat flatndjson \
  -output /dev/stdout | logger -t TYCHON

# Syslog forwards to LogRhythm collector
# Protocol: UDP/TCP 514 or TLS 6514

Method 3: CEF Integration

Common Event Format for structured security events

# Scanner outputs CEF format
./certscanner -host targets.txt -outputformat cef \
  -output /var/log/tychon/cef-events.log

# LogRhythm parses CEF automatically
# Enhanced field mapping and correlation

Method 4: REST API

Direct API integration for real-time event ingestion

# Custom integration via LogRhythm REST API
curl -X POST "https://logrhythm.company.com/lr-admin-api/logs" \
  -H "Authorization: Bearer $LR_TOKEN" \
  -H "Content-Type: application/json" \
  -d @tychon-scan-results.json
