A comprehensive guide for deep packet inspection and network forensics using Wireshark and tshark. This skill is critical for incident response, where it allows users to capture, filter, and analyze network packet data to identify malicious command-and-control traffic, diagnose complex protocol issues, extract indicators of compromise (IOCs), and reconstruct data exfiltration paths. Use it for validating security rules and understanding network anomalies.

This tool detects critical anomalies in DNP3 communications used within SCADA and ICS environments. It employs deep packet inspection and machine learning to monitor for unauthorized control commands, protocol violations, firmware update attempts, and deviations from established network baselines. It is essential for securing critical infrastructure, such as energy grids and industrial control networks, and building robust anomaly-based Intrusion Detection Systems (IDS).

This comprehensive guide details the deployment and configuration of Tofino industrial firewalls to secure critical SCADA and PLC systems. It utilizes Deep Packet Inspection (DPI) capabilities for core OT protocols (Modbus, EtherNet/IP, S7comm), ensuring strict access control and enforcing IEC 62443 zone boundaries. Ideal for segmenting control networks and providing compensating controls for unpatchable legacy equipment.

Automates deep packet inspection using tshark and pyshark on PCAP files. This tool is designed for cybersecurity professionals to perform structured network forensics, compute protocol distribution, detect suspicious activity (like port scans, beaconing, and data exfiltration), extract critical IOCs (IPs, domains, URLs), and identify advanced threats such as DNS tunneling patterns. Ideal for incident response and security auditing.

This tool monitors Modbus TCP communication within SCADA and ICS environments to detect security anomalies. It performs deep packet inspection, baselines normal communication patterns (e.g., typical function code distribution, register access), and applies statistical analysis to identify unauthorized register writes, reconnaissance attempts, or denial-of-service attacks targeting industrial control devices.
