Phoenix Contact receives IEC 62443 certificate for PLCnext Control by TÜV SÜD

March 14, 2022

Phoenix Contact received a certification for a programmable logic controller (PLC) in accordance with IEC 62443-4-1 ML 3 Full Process Profile in combination with IEC 62443-4-2. This confirms that the secure development life cycle was applied in developing the PLCnext Control devices.

As a result, the PLCnext Control product family of AXC F 1152, AXC F 2152, and AXC 3152 has been certified by TÜV SÜD. By activating the Security Profile, users have access to a more comprehensive scope of Security Level 2 (SL2) functions. This certification emphasizes Phoenix Contact's strategy of offering standardized security in products, industry solutions, and consultation services to ensure the future-proof operation of machines, systems and infrastructures.

"The IEC 62443 standard series defines the security requirements for the development process and the functional product characteristics. Integrating these into an open platform such as PLCnext was a true challenge, which was solved elegantly by introducing the Security Profile," said Enrico Seidel, senior OT security expert at TÜV SÜD.

Heiko Adamczyk from TÜV SÜD added: "Product certification in accordance with IEC 62443-4-1/-4-2 shows users that a product was developed securely and provides information on which technical security requirements were implemented. Our Certificate Report describes which product characteristic achieved which Security Level. Collaboration with TÜV SÜD during development was very goal-oriented, allowing the time requirements of the complex project to be taken into account on an individual basis."

Boris Waldeck, IEC 62443 Certification project manager at Phoenix Contact, said: "Implementation of the development-side 4-1 process requirements, for instance with the definition of the security context, threat analysis, secure-by-design concepts and implementations, vulnerability management, and the establishment of security test methods, were the key building blocks of the certification."

"Implementing the security functions of IEC 62443-4-2 in accordance with the standard required close collaboration with TÜV SÜD, since requirements in 4-2 are often only described in very general terms," added Stefan Hausmann Product Solution & Security Expert (PSSE) at Phoenix Contact.
