ntopng

ntopng is a network traffic monitoring application that analyzes network traffic and presents it in a human-readable format. It is the next generation version of the original ntop and offers a web-based interface for real-time network monitoring and historical data analysis.

ntopng's core function is to capture network packets and analyze them to identify hosts, protocols, applications, and other relevant network characteristics. It then aggregates this data and provides insights into network performance, security threats, and potential bottlenecks.

Key features of ntopng typically include:

• Real-time Network Monitoring: Allows users to see the current network activity, including active hosts, flows, and protocols.
• Historical Data Analysis: Stores network traffic data for later analysis, enabling trend identification and troubleshooting.
• Web-Based Interface: Provides a user-friendly graphical interface accessible through a web browser.
• Protocol and Application Identification: Recognizes various network protocols and applications, providing detailed information about the traffic generated by each.
• Geolocation: Can map network traffic to geographical locations.
• Flow Analysis: Identifies and tracks individual network flows, providing details such as source and destination addresses, ports, and protocols.
• Reporting and Alerting: Generates reports on network activity and can send alerts based on predefined thresholds or events.
• Security Monitoring: Detects suspicious network behavior and potential security threats.

ntopng is commonly used by network administrators, security professionals, and other IT personnel to monitor network performance, troubleshoot network issues, and identify security threats. It is available in both open-source and professional editions, with the professional edition offering additional features and support.
