A major milestone has been reached towards the aim of making Industrial Control and Automation systems compliant with the required level of Cyber Security, so as to minimize vulnerability to cyber-attacks.
It concerns the completion and publication of the standard IEC 62443-2-4: Security for Industrial Automation and Control systems, Part 2-4: Security program requirements for IACS service providers (Formerly ISA-99). An overview of the IEC 62443-2-4 series of standards can be found here. This IEC standard is now available for sale from the Dutch office for Norms and Standards.
The next step in this process is to set-up compliance testing and certification schemes to provide a solid foundation for enhanced security throughout the process industries.
