ISA99: Developing the ISA/IEC 62443 Series of Standards on Industrial Automation and Control Systems (IACS)

Welcome to the ISA99 Committee Wiki!

NOTICE: The content of this Wiki site is no longer being maintained by the committee. A plan is being developed to move this material to the ISA99 committee web page.

The ISA99 committee provides this site as a means of facilitating collaboration both within the committee ands with interested stakeholders. Anyone can use the links provided on these pages to review recent committee news and monitor committee activities.

The following depicts the status of the various work products in the ISA/IEC 62443 series of IACS standards and technical reports.

ISA-62443 Series

Information is available about the composition and status of the various committee  work groups, as well as a page devoted to the topic of committee participation (including instructions on how to join the committee).

Global IACS Experts - and Close Collaboration with IEC TC65

The ISA99 committee currently includes 500+ members representing organizations and industry sectors from across the globe. Although ISA is an accredited standards developing organization in the US, the ISA99 committee is open to participation at no fee from virtually all interested parties.


In addition to an international membership, ISA99 has a strong collaborative relationship with IEC TC65 WG10 by which the primary responsiblity for developing the documents of the ISA/IEC 62443 series highlighted above is with ISA99, with the exception of  IEC 62443-2-4.



ISA99 Purpose


The purpose of the ISA99 committee is to develop and establish standards, technical reports and related information that will define procedures for implementing electronically secure industrial automation and control systems and security practices and assessing electronic security performance. Guidance is directed towards those responsible for designing, implementing, or managing industrial automation and control systems as defined in the committee scope. This guidance also applies to users, system integrators, security practitioners, and control systems manufacturers and vendors. 


ISA99's focus is the improve the confidentiality, integrity, and availability of components or systems used for industrial automation and control, and provide criteria for procuring and implementing secure control systems. Compliance with ISA99's guidance is intended to improve system electronic security and help identify and address vulnerabilities, reducing the risk of compromising confidential information or causing degradation or failure of the equipment of process under control.


Committee Governance

All work and activities of the ISA99 committee are governed by the general procedures and rules established by the ISA Standards and Practices board. More information is available on the ISA web site. In addition the committee has defined more specific and detailed governance processes and procedures that assist in guiding committee activities.

In the case of a large collection of related standards and reports such as those that form the ISA99 work plan it is critical that there be consistency across the various documents with respect to terminology and the concepts or elements that form the basis for the positions taken in the standards.
