Information systems employed in Operations (including industrial control systems) are often subject to very stringent requirements related to information integrity and performance. Functional needs such as these can lead to the identification of secondary requirements and constraints in areas such as cybersecurity. The challenges associated with securing industrial control and related systems have in turn been topics of considerable discussion, debate, and analysis for the past several years. The ISA99 committee and IEC Technical Committee 65 Working Group 10 have developed the 62443 series of standards that provide requirements and guidance on all aspects of the subject. This information is deliberately expressed in broad terms, allowing it to be applied across a wide range of industries and situations.
