CIP Security Moves EtherNet/IP Security Into Hardware Design

EtherNet/IP security is becoming a hardware design issue, with certified SL3-capable requirements pushing trusted boot, identity, and key protection into the product architecture.

Updated

What is this trend?

CIP Security is turning EtherNet/IP security into a hardware design requirement, pushing trusted boot, key protection, and interface lockdown into product architecture.

  • ODVA’s CIP Security now has SL3-capable certification for EtherNet/IP communication security.
  • Vendors still must prove their own implementation in hardware, firmware, and manufacturing.
  • Secure boot, device identity, and protected keys are becoming baseline design elements.
  • Debug ports, physical access, and update paths now need security validation, not just functional testing.
  • Hardware engineers must produce security evidence and traceability earlier in the development cycle.

What’s the latest?

On June 15, 2026, TÜV Rheinland certified ODVA’s CIP Security specification Editions 1.19–1.21 to IEC 62443-4-2 Security Level Capability 3.

How it developed

  1. Autonomous labs, RTL verification agents, and design-time compliance move engineering work upstream
  2. Cadence, Siemens, and New Entrants Turn Agentic EDA Into a Platform Race
