PLC Service - zakharb/labshock GitHub Wiki

Labshock provides multiple PLC services to simulate, test, and analyze Programmable Logic Controllers (PLCs) in an OT environment. These services support industrial automation, cybersecurity research, and integration with monitoring tools like SIEM and IDS.

PLC services in Labshock allow users to:

• Deploy and manage virtual PLCs.
• Simulate industrial control logic.
• Communicate using standard automation protocols.
• Monitor PLC activity and log events for security analysis.

Labshock includes different PLC implementations, each designed for specific use cases, such as testing real-world scenarios, detecting attacks, or integrating with OT security solutions.

OpenPLC is an open-source PLC runtime that supports standard industrial automation protocols. It provides a web-based interface for managing and monitoring PLC logic.

Labshock contains modified version of OpenPLC
