Growing International Collaboration
Although most of the ISA/IEC 62443 standards were originally created by the International Society of Automation (ISA), the subsequent collaboration with IEC Technical Committee 65 Working Group 10 has been very effective in extending awareness and interest globally. Adoption in the European Union has received considerable attention, but there has also been similar adoption in other countries and regions. This is the ultimate goal for a truly international standard, since the issues associated with securing automation and control systems are not confined to specific industries or geographies.
Australia’s Recent Announcement
One of the more recent examples of increasingly global adoption was announced by Standards Australia in July. This follows similar adoptions in other Asia-Pacific countries, such as Japan and Singapore.
Key Benefits of Adoption
The Australian announcement cites several specific benefits to adoption, including:
Protection of public health by helping to reduce the risk of system failures caused by cyberattacks,
Support of social stability by safeguarding the essential services communities rely on,
Boosting economic opportunities by allowing consumers to safely participate in energy markets, such as selling power back to the grid, and
Reducing reputational risk by minimizing the chance of prolonged outages and public fallout for organizations managing critical infrastructure.
Evolving Standards and Industry Needs
One of the more significant statements in the Australian announcement begins with “The IEC continues to evolve these standards ...” This shows that Standards Australia recognizes there is still much work required to mature the 62443 standards to meet all existing and developing industry needs. This provides an opening for ISA99 and IEC TC65 WG10 to encourage more participation from this part of the world.
The Need for Wider Global Engagement
Similar outreach in other regions is necessary if the standards are to live up to their reputation as international standards. Examples include South America, the Middle East, and Africa. In many cases, this requires engaging with regulatory and other governmental bodies. The ISA99 committee welcomes participation from any constituency, anywhere in the world.
