The International Society of Automation (ISA), the professional society for automation, announced the publication of ANSI/ISA-62443-2-1-2024, Security for Industrial Automation and Control Systems. It is the latest update to the ISA/IEC 62443 series of standards, the widely used global automation and control systems cybersecurity standards.
Addressing cybersecurity on an organization-wide basis can be a daunting challenge for companies that rely on industrial automation and control systems (IACS) in their manufacturing, processing, and critical infrastructure operations. While no one-size-fits-all set of security practices can meet the widely varying security needs across global industry, ANSI/ISA-62443-2-1-2024 addresses the complexity by setting forth requirements for establishing, implementing, maintaining, and continually improving a security program intended to reduce IACS security risks to tolerable levels.
The requirements are written to be implementation independent, allowing asset owners to select approaches most suitable to their needs. This update of the 2010 version provides significant technical changes, including a revision of the requirement structure into security program elements and a maturity model for evaluating requirements.
The standards are developed by the ISA99 Standards Committee as American National Standards, with simultaneous review and adoption by the Geneva-based International Electrotechnical Commission. ISA99 draws on the input of cybersecurity experts across the globe in developing the standards, which are applicable to all industry sectors and critical infrastructure in providing a flexible and comprehensive framework to address and mitigate current and future security vulnerabilities in IACS.
