Industrial network security
As the manufacturing sector becomes increasingly digital and new connections are being made between products and machines, the demand for security is no longer limited to protecting people from machines, but to protecting machines from human intrusion and thus avoiding unauthorized influence from outside (cyberattacks).
In Industry 4.0, the standard IEC 62443 (Industrial Communication Networks – Network and System Security) has become an internationally recognized standard in the process and automation industry. The series of standards consists of 11 parts. They address the logical relationships between organizations/processes, systems and components, and process-related functional requirements. IEC 62443 thus represents the standard for the entire industrial sector and meets the requirements of operators, integrators and manufacturers. In the audit of processes and systems, both traditional business structures (TIC testing, inspection, certification) and methods of product testing or component certification are considered.
