Open Source Software: ICSNPP: Advanced Industrial Control System Protocol Parsing for Zeek

In an era where industrial control systems (ICS) are increasingly targeted by sophisticated threats, ensuring robust network security is paramount. ICSNPP (Industrial Control System Network Protocol Parsers) emerges as a critical solution, providing an advanced protocol parser suite that integrates seamlessly with the Zeek network security monitoring framework.

The evolution of cyber threats targeting industrial environments necessitated the development of specialized tools capable of understanding and monitoring the unique protocols these systems use. DHS/CISA funded ICSNPP to address this gap, enhancing hunt and incident response capabilities within ICS environments. This project aims to bolster the security of CISA's network sensors and democratize access to this advanced technology by making it open-source on GitHub.

ICSNPP is a collection of Zeek plugin protocol parsers tailored for the industrial control sector. It currently supports four major ICS protocols: BACnet, DNP3, Ethernet/IP, and Modbus, with expansion plans. Unlike general Zeek protocol parsers, ICSNPP delves into the intricacies of ICS communications, offering detailed insights into network activities. This enables more effective monitoring, threat detection, and incident response in critical infrastructure networks.

Advantages:

• Detailed Protocol Analysis: Unmatched depth in parsing ICS-specific protocols for comprehensive network visibility.
• Quick and Easy Integration: Installs in less than 5 minutes, immediately enhancing security monitoring capabilities.
• Open-Source Accessibility: Freely available for use and contribution, fostering a community-driven approach to ICS security.
• Proactive Threat Hunting: Facilitates advanced threat detection and response tailored to the unique environments of industrial control systems.
• CISA-Tested Reliability: Undergoing rigorous testing by CISA to ensure effectiveness and reliability in real-world scenarios.

Applications:

• Energy Sector: Optimize renewable energy integration with enhanced network security and monitoring.
• Manufacturing: Secure manufacturing processes by ensuring the integrity and availability of ICS networks.
• Water Treatment Facilities: Protect critical water treatment operations through advanced network threat detection.
• Critical Infrastructure: Enhance the resilience of critical infrastructure by improving visibility into network activities and threats.
