• Navigate to the "Devices" tab and click "Add Device".
• Enter the IP address or hostname of the firewall device you want to monitor.
• Provide authentication credentials (e.g., SSH, SNMP) for accessing the firewall device.
• PRTG will automatically discover available sensors for firewall monitoring.

Configuring Firewall Monitoring Sensors:

• Select the appropriate firewall monitoring sensor (e.g., SNMP Traffic Sensor, SNMP Custom Sensor).
• Configure sensor settings such as monitoring intervals, traffic thresholds, and authentication details.
• Define specific firewall parameters to monitor, such as inbound/outbound traffic, connection counts, and security events.

Dashboard Customization:

• Customize the dashboard to display firewall activity and security event metrics.
• Add widgets for real-time and historical data visualization.
• Arrange the layout for easy monitoring of firewall activity and security events.

Setting Up Alerts:

• Configure alerts for firewall security events or abnormal activity.
• Define thresholds for acceptable traffic levels, connection counts, and security event rates.
• Choose notification methods (email, SMS) for alerts to ensure timely awareness of firewall issues.

Historical Data Analysis:

• Analyze historical data to identify trends in firewall activity and security events.
• Generate reports to gain insights into firewall uptime, traffic patterns, and security event trends over time.
• Compare data across different firewall devices or periods for performance evaluation and troubleshooting.

Security Incident Response:

• Use security event data to respond to security incidents promptly.
• Investigate security events to determine the root cause and impact on the network.
• Take appropriate actions to mitigate security risks and prevent further incidents.

Integration and Automation:

• Integrate PRTG with other security tools for enhanced functionality.
• Automate monitoring tasks such as alert acknowledgments and incident response actions.
• Leverage third-party integrations for advanced analysis and reporting of firewall activity and security events.

Maintenance and Updates:

• Keep PRTG updated to access the latest features and security patches.
• Monitor PRTG health for optimal performance.
• Perform routine maintenance tasks like database cleanup and sensor optimization.

By following these steps, you can effectively monitor firewall activity and security events using PRTG Network Monitor, ensuring that your network remains secure and protected against potential threats.
