    # Add bot
    await tracker.add_bot("bot_001", "192.168.1.100", {
        'version': '2.0',
        'capabilities': ['file_transfer', 'remote_shell']
    })
    
    # Update activity
    await tracker.update_bot_activity("bot_001", "command_completed")
    
    # Get status

🔒 Security Considerations

🛡️ Security Best Practices

Network Isolation: Always run in isolated test environments
Access Control: Use strong admin passwords and rotate regularly
Encryption Keys: Generate unique keys for each deployment
TLS Certificates: Use valid certificates for production testing
Logging: Monitor logs for suspicious activity
Updates: Keep dependencies updated and audit regularly

🚨 Security Warnings

Never deploy on production networks
Do not use default configurations
Always use strong authentication
Monitor all network traffic
Implement proper access controls

🔍 Security Auditing

# Run security scan
bandit -r . -f json -o security-report.json

# Check dependencies
safety check

# Validate configuration
python -c "
from utils import SecureConfig
config = SecureConfig()
assert config.get('ENCRYPTION_KEY') is not None
print('✅ Security configuration validated')
"

🛠️ Troubleshooting

Common Issues

Import Errors

# Issue: Module import failures
# Solution: Check virtual environment and dependencies
source venv/bin/activate
pip install -r requirements.txt
python -c "import utils"

Permission Errors

# Issue: Port binding permission denied
# Solution: Use ports >1024 or run with appropriate permissions
export BOTNET_PORT=9999  # Use high-numbered port

Encryption Key Errors

# Issue: Invalid encryption key format
# Solution: Generate proper base64-encoded key
python -c "import os, base64; print(base64.b64encode(os.urandom(32)).decode())"

Connection Issues

# Issue: Cannot connect to server
# Solution: Check network configuration and firewall
netstat -tlnp | grep 9999  # Check if port is listening
telnet localhost 9999      # Test connection

Debug Mode

# Enable debug logging
export BOTNET_LOG_LEVEL=DEBUG

# Run with verbose output
python botnet_controller.py --verbose

# Check system resources
top -p $(pgrep -f botnet_controller)

Performance Issues

# Check memory usage
python -c "
import gc
from utils import BotTracker
tracker = BotTracker()
print(f'Objects before: {len(gc.get_objects())}')
# ... perform operations ...
gc.collect()
print(f'Objects after: {len(gc.get_objects())}')
"

# Profile performance
python -m cProfile botnet_controller.py
