Cybersecurity: Integration of Palo Alto Networks Next Generation Firewall to Secure the Schneider Electric MTZ Circuit Breaker

In this paper, we shall illustrate the integration of Palo Alto Networks firewalls in securing the MTZ circuit breaker by implementing Deep Packet Inspection on the modbus TCP protocol. The MTZ circuit breaker is a key component for the future of power distribution. It must be integrated into TCP/IP networks using a defense-in-depth strategy with guidance provided by the ISA/IEC 62443 Standard.
